By installing Airius destratification fan systems, financed through energy efficiency funding, La Plateforme du Bâtiment achieved outstanding results:
Operating from six sites within the UK, Norco has established itself as a leading developer of innovative plastic mouldings and lightweight composite structures, working alongside major construction companies, the defence sector and marine industry, including serving as chief mould maker for Sunseeker luxury yachts.
The high ceilings across all of Norco’s 80,000 ft2 production facilities in Poole, Dorset, led to severe stratification issues, as the heat from the HVAC system was immediately rising to the ceiling and being lost through the roof.
Despite the heating system running continuously, which incurred high energy costs, it was still unable to reach comfortable conditions at floor level. The imbalance in temperatures was also resulting in condensation issues, hot and cold spots and a high carbon footprint.
After carrying out a free site survey a series of Airius model 25 Standard Series destratification fans were specified to recirculate the heated air from the ceiling back to the floor.
Taking advantage of Airius’ full turn-key solution, which provides a completely managed, stress free, design, supply and installation service, the system was fitted within a week with minimal disruption to Norco’s operations.
Following installation a balance of temperature was achieved, optimising comfort while significantly reducing heating costs. Air flow circulation was improved and condensation was virtually eliminated. In addition, the Airius system efficiently recycles heat from manufacturing processes, further decreasing the load on the HVAC system.
These energy savings contributed to Norco’s environmental initiatives, solidifying their position as leaders in the ‘Green Pea Positive Environmental Action Scheme’.
“We now have Airius destratification fans in all of our main production facilities totalling 80,000 sq ft. Each installation was carried out professionally and to an excellent standard, with the minimum of interruption to our very busy manufacturing facilities. The main benefits for us are the vastly improved air circulation, balance of temperature throughout the buildings, low running costs, silent and stress free operation and of course a fantastic saving on our gas utility bill per annum. I would highly recommend Airius systems for all factory and warehouse environments.” Mark NorthyDirector

Freedom Leisure is one of the UK’s leading not-for-profit charitable leisure and cultural trusts, operating over 100 leisure, cultural and entertainment venues across the UK.
Maintaining comfortable environments in leisure centres can be notoriously difficult and expensive, especially in swimming pool spaces. To address these challenges Environmental and Sustainability Manager Angela Brown from Freedom Leisure sought a solution that would help reduce swimming pool space heating costs at their Hailsham Leisure Centre and Malvern Splash Leisure Centres without compromising poolside temperatures and comfort, while also cutting carbon emissions in line with their strategy to become net zero by 2030.
Following a free site survey the Airius Standard and Onyx Series was installed to recirculate high level heat accumulated at the ceiling back to the floor. This immediately improved heating efficiency, with some areas even overheating at existing set points, leading to a reduction on the thermostat. Poolside comfort complaints from spectators also ceased. Heating costs were then monitored following installation, recording a 62% saving at the Hailsham Centre and a 41% saving at the Malvern Splash Centre.
“The success at these initial sites have now allowed Freedom Leisure to apply for funding and grants across England and Wales with the acceptance of multiple councils, including being invited to Stage 2 Application by Sport Wales.” Angela Brown Environmental and Sustainability Manager

“Following install Initially poolside at Malvern Splash became too hot, with the poolside temperature increasing by 7°C. The setpoint was adjusted from 29.5°C to 26°C immediately. This resulted in a 41% reduction in gas consumption for space heating the pool area in the first week of measuring results.” Chris Wedgbury Area Technical Manager

The London Aquatics Centre is a world-class swimming and diving venue based at Queen Elizabeth Park, host to the 2012 Olympic Games. The Centre features a 50 metre competition pool, 50 metre training pool and 10 metre high diving pool with the capacity to hold up to 2,800 spectators.
As with most pools and sports buildings, heat supplied from HVAC systems was rising up to the high ceilings, away from swimmers and spectators in the zone of occupancy at floor level. This not only meant that it was near impossible to maintain comfortable temperatures at the floor, despite the high heating costs, but the increased temperature at the ceiling accelerated heat loss to the outside, further compounding the problem and pushing energy costs even higher.
To resolve the issues of uncomfortable temperatures and poor heating efficiency 25 x Airius Model 60 Standard Series fans were specified to be installed throughout the space. This allowed for the heat at the ceiling to be continuously recirculated back to floor level, balancing temperatures, improving comfort and reducing the load on the HVAC system substantially. In the 14 months following installation the centre saved over £150,000 on heating costs, reduced their CO2 emissions significantly and benefited from an ROI of only 5 months.
Formed in 2004, we have revolutionised the industry with our market leading thermal destratification systems, which have helped improve airflow circulation and balance the internal temperatures in public and commercial buildings all around the globe. As testament to the efficiency of the Airius system, we have built up an extensive and prestigious global client base including well-known brands like Boots, British Airways, Mercedes, Morrisons and many more.
We can help you cut your costs with our thermal destratification systems, which recirculates accumulated warm air collected at the top of a building back down to the ground through an invisible column of air. This is then redistributed at floor level, recycling the heat which you have already supplied to the space, reducing the output and workload on your heating system. It also works with cooling. By continuously circulating the heavier and denser cooled air evenly throughout the space in its entirety, it eliminates hot and cold spots and ensures conditions are balanced for all.
When you choose Airius, you will be investing in the most effective thermal destratification system available on the market with an average ROI of between 6 – 24 months. Airius are also the only destratification fan supplier in the world to offer an unrivalled 120 day money back guarantee (terms and conditions apply).
Virgin Active Gyms are opening new facilities across Australia and Asia and they are keen to provide an energy efficient and unobtrusive gym cooling solution for the users of their gymnasiums and exercise centres.
Their flagship facility is located at Barangaroo, by the Sydney waterfront, and provides a range of exercise opportunities including cycling, yoga, boxing, weight rooms, and numerous other exercise configurations.
David Shreeve from DSA and Associates, director and mechanical engineer and long a supporter of the Airius products, recommended the use of the fans to Virgin Active as a methodology to reduce air conditioning ductwork and running costs, while at the same time providing an unobtrusive solution. Typical ceiling fans weren’t suitable due to low ceiling heights and their distraction and interruption to activities, while they also were limited in their mounting locations.
Primarily though, the Airius fans offered an unmatched ability to move the conditioned air around the space and over distance that no ceiling fan can match.
The Airius gym cooling solution offers both ceiling and roof mounted options and the request from Virgin for the fans to be black was easily fulfilled by Airius.
Virgin Active and DSA are so thrilled by the results that they have subsequently installed the Airius fans into two more Virgin Active facilities; Market St. and Bridge St. in the Sydney CBD.
Their unique look, small size, large amount of air movement, full BMS control capability and very low 30 Watt power consumption has worked in perfectly with the Virgin Active design brief.

The Kingdom Shopping Centre is one of the largest single-level indoor shopping centres in Scotland with around 40,000m2 of floorspace.
The centre contains over 100 retail units, featuring brands including Argos, Boots, Sports Direct, Iceland, JD Sports and New Look, as well as a variety of cafés, the town’s central library and theatre/civic centre.
Retailers made requests to the shopping centre to improve heating levels, as units were uncomfortably cold despite the high heating bills. The centre is heated by 20 gas fired air handling units, set to run daily from 8am to 5pm. So, Kingdom set out to find a solution that would not only improve heating comfort, but also conserve energy.
Airius worked with Kingdom Shopping Centre to design and install a series of 26 Airius Destratification fans throughout the Centre, including its 2 squares, central walkway, theatre and library. Installation was completed out of hours to avoid any disruption to normal opening hours. The results exceeded expectations and improved the comfort of shoppers and workers in the Centre, whilst reducing the amount of energy used by 15%. This reduction in gas usage over a four month period enabled significant reductions in the cost and carbon emissions. The project was such a success that it was awarded ‘The Green Apple – Gold Award’ for environmental best practice.
“I would recommend Airius Destratification Fans to other organisations and communities, especially if they have high roofs, ceilings or atriums, where the warm air rises, is trapped and wastes precious fossil fuels.” John Bell – Kingdom Shopping CentreOperations Manager
“I would recommend Airius Destratification Fans to other organisations and communities, especially if they have high roofs, ceilings or atriums, where the warm air rises, is trapped and wastes precious fossil fuels.”
Gym environments, where groups of people are in close proximity, equipment is shared between numerous people and heavy breathing takes place as a result of aerobic exercise, present a high-risk environment for the transmission of COVID19. In order to ensure the safety of their members and staff Energie Fitness turned to Airius and the PureAir air and surface purification solution.
After an initial consultation with the Airius design team a series of PureAir units were specified for the facility, accompanied by a series of standard Airius destratification fans. This widened the stand-alone coverage of the PureAir units by using additional fans to circulate the PureAir’s active cleaning agents throughout the Gym space. Speed controllers were also included to control airflow speed.
Energie Fitness have been extremely impressed with the results from their new PureAir system:
Following the reopening of fitness facilities in April, 2021, members have been able to return to the Gym at Energie Fitness reassured in the protection provided by the Airius PureAir system, not only from COVID19, but from all types of communicable pathogens and viruses. Previous problem odours commonly associated with training and fitness facilities have also now been removed, replaced by clean, fresh, odour free air. In addition, the improved airflow and destratification benefits of the Airius system works to optimise existing heating and cooling systems, ensuring balanced conditions throughout without hot and cold spots, whilst reducing HVAC energy consumption by up to 50%.
“Energie Fitness Wokingham opened it’s doors this year in a climate where cleanliness and hygiene was paramount. Since then, members have been highly impressed with the additional care that has gone into ensuring our gym puts their safety first. We believe this is, in large part, down to the installation of the Airus PureAir system. This feature is a unique selling point in attracting members and a key driver in retaining those we have. Our satisfied and loyal customers frequently comment on how fresh the air is inside the gym and how safe they feel during each visit.” Anthony Cromack (Owner)Energie Fitness Wokingham

Oil prices dropped by an average of 9.5% in 08/09 compared to the previous winter period 07/08. This will enhance the actual savings.
The mean temperature for East Anglia during winter 07/08 was 5.7°C. The mean temperature for East Anglia during winter 08/09 was much cooler at 3.4°C.
The heating system thermostats are set to 16°C, resulting in an increase in the requirement for heating in East Anglia of 22%.
This analysis excludes the purchase and installation costs of £21,268 in the first year.
YMCA Warwick located in southwest QLD and provides a facility for a range of indoor sports.
Their facility covers two basketball courts and surrounds and is 10 metres high and approximately 1,100 sq. metres in overall size.
It is used by both the YMCA and assorted associations and groups for a range of sports.
YMCA had considered the use of large bladed fans however the Airius option offered the best price without the expense of running three phase power or relocating the lighting. Plus, the client was concerned at the damage balls etc. can make to large bladed fans, as well as the required annual maintenance costs HVLS large bladed fans require.
As assorted other YMCA facilities around Australia use Airius fans for cooling, David Jordan, the facility manager, approached Airius for a cooling solution in his facility using their unique fans.
After a review of the supplied floor plans and photos, Airius recommended the installation of 8 x Airius Sapphire Series fans, suspended just off the ceiling and evenly spaced around the facility.
These fans work together as a system and push out massive volumes of air. They have a thrust rating of 14.32 Newtons and a C/L velocity at 10 metres of 2.89 m/s.
YMCA accepted the Airius proposal adding to the scores of facilities around Australasia and Asia now using the Airius Sapphire Series fans for cooling their large spaces. Their ease of install, and unobtrusiveness, coupled with all their other benefits (compared to every alternative fan type) made the decision easy.
The German EBM Papst EC motor (regarded as the world’s best fan motors) which powers the fans, is controlled by either a BMS or by an infinite speed potentiometer controller. Airius supplied two of these controllers -one per four fans per court.
The client was extremely happy with the results and David Jordan, Facility Manager for YMCA Brisbane, said “Airius fans in our stadium have made a massive difference to the air flow, comfort levels and PR at the Warwick Indoor Recreation and Aquatic Centre (WIRAC). They were very easy to install and won’t have the same maintenance nor programming issues as the HVLS fans, which wouldn’t have coped with the futsal balls bouncing off the rotating blades!”
The Farnborough Exhibition and Conference Centre is a 20,000m2 exhibition hall based at Farnborough Airport in Hampshire. Owned and operated by the ADS Group, a premier trade organisation for over 1,000 Aerospace, Defense and Space Sector businesses, the Farnborough Exhibition Centre boasts international acclaim as the home of the world famous Farnborough Airshow.
As with many exhibition hall spaces, maintaining comfortable temperatures, especially during winter months, proved extremely difficult as the heat supplied to the space was rising to the ceiling and escaping through the roof. This resulted in exorbitant heating costs, despite the fact that the hall still couldn’t achieve desired, comfortable temperatures at floor level. It also resulted in high CO2 emissions, which was working against the clients CSR and climate change reduction strategy.
To reduce the negative impacts of rising heat being lost through the roof, the client installed 94 Standard Series destratification fans throughout the hall. This continuously recirculated all the warm air supplied by their HVAC system, down away from the ceiling back to the floor where it was needed. This balanced temperatures to within 2ºC between the floor and ceiling and reduced heating costs so much that they benefitted from an ROI of under 12 months.
As one of the leading Hospitals not only in Ireland but also across the wider continent of Europe, the Beacon Hospital set out to source an air and surface purification solution that would not only provide the highest level of protection for its patients and staff, but one that also incorporated the latest in cutting edge technology, reinforcing its title of a leading advanced healthcare provider.
After carrying out some extensive research on the wide array of purification systems available, the Beacon Hospital selected the Airius PureAir system to be installed within its clinics and workshop facilities.
Installation was carried out by their own contractor, Ermen Systems and was completed with minimal disruption to the Hospital.
The effect of Airius PureAir Series may be invisible, but the results are unmissable:
Both patients and staff at Beacon Hospital feel more reassured and protected against communicable diseases, including COVID19 and the PureAir System has now become a core component of the Hospital’s Infection Prevention Control strategy, with plans to install more units throughout their facility.
“We have installed a number of Airius fans over the last couple of months and intend to continue to do so. We have installed these in workshops and clinics and have found the air to be fresher, more comfortable and all odours and smells have been eradicated.
It has created an area of confidence among staff and patients that they are being protected. We have also noticed we have reduced our heating settings with the benefit of savings on energy costs.The resident facility management company who look after the Beacon Mall have also committed to rolling these units out in September.”
Sean Penston – Director of Facilities, Beacon Hospital
Lush Retail Ltd needed to improve internal conditions at their Hatch Pond Road factory facility in Poole, Dorset. Temperatures at floor level were uncomfortably cold as their heating system was unable to reach acceptable conditions. This also incurred high energy costs as the heating system was running constantly in an attempt to reach set parameters.
Following installation of the Airius system heating costs for the site were reduced by over 60%. Lush are now installing the Airius system throughout the rest of their factory facilities.
Usagefor November and December 2012 calculated by dividing the COST by the average amount per unit throughout the year. COST for March 2013 calculated by multiplying units used by average amount per unit throughout the year. 20% of consumption allowed for heating the offices and hot water.
Gas used for production processes approx. £220 per month. Calculated from average amount used throughout June, July & August when the heating is off. This has been subtracted to leave only heating gas.
A drop in temperature of one 1ºC increases a buildings heat load by 8% to 12%, mainly depending on the base temperature and the building fabric. With the low level of insulation at the Lush Hatchpond Road facility calculations are based on a very conservative 11% per 1ºC. The overall adjustment for the temperature difference works out as a 16.33% increase to the pre Airius figures.
All the final outcomes are shown in the data above including; WITHOUT weather effects taken into account, WITH weather effects taken into account and an AVERAGE of the both.
The Airius units in the Hatchpond road site have far exceeded predicted savings. This is mainly due to the buildings extremely low level of insulation and the high level of process heat within the environment, which when recirculated provides a free source of space heating.
The accompanying thermal images were developed from the temperature controlled warehouse of a major pharmaceuical company. The company’s new 50,000 sq t. warehouse facility in Louisville, KY did not pass the Food and Drug Administraion’s required Temperature Validaion Tests with the originally designed HVAC system.
As can be seen in the ‘Before Airius’ image without Airius fans, the top levels of the pallet racking were exposed to 22.5°C air, too high a temperature for the inventory.
This was a major problem; the facility was due to open and the space was badly needed. The HVAC contractor had tried everything they could think of and had no answers for the problem, short of staring over with a re-designed system. A senior facility engineer suggested the use of Airius for this application. The HVAC Contractor was very sceptical the devices could raise the cold air levels and maintain them. Airius personnel were called in to review the situation and it was determined for this large application that 50 Airius model 25 destratificaion fans would be required and were air freighted at the customer’s request within 2 days.
The facility quickly agreed and the installation was a success. In spite of the fact that the destratificaion fans were originally developed to de-straify heated air, and the fact that cold air naturally sinks, it can be seen by comparing the ‘Before Airius’ image to the ‘After Airius’ image that the use of the Airius fans has balanced the level of cooler air in the room to the point where the upper rack levels are no longer in jeopardy – Thermal Equalisation!
The elevation graphic shows a complete equalisation of temperature around the pallet racks supporting literally billions of dollars of inventory from floor to ceiling meeting FDA regulations and approval.
Timberline Gardens was an independent, 10 acre garden centre supplying over 2,400 species of plants and perennials. Including both indoor and outdoor growing facilities, award winning Timberline Gardens operated for nearly 20 years, helping owner and Director Kelly Grummons achieve ‘Nursery & Greenhouse Association Person of the Year’ in both 1992 and 2002.
During the cold winter season heat was rising and being lost through the greenhouse rooves, resulting in excessively high heating costs. Plant growth was stunted due to the difficulty in maintaining optimal growing conditions at plant level. Customers and staff also found conditions uncomfortably cold, negatively impacting browsing time and productivity.
In order to prevent the rising warm air from being lost, the centre installed Airius’ Standard Series destratification fans throughout their greenhouses. The results were immediate, improving thermal comfort significantly the moment the units were turned on. Airflow circulation was improved, eliminating previously unproductive planting areas and increasing winter plant growth. The ability to maintain consistent thermal conditions also improved blooming by 25%, whilst reducing energy costs for heating by 26%, resulting in an ROI of only 6 months.
In response to the COVID19 Pandemic Harewood Dental Surgery needed to find a solution to help provide protection and reassurance for their staff and patients against the threat of infection from Coronavirus and other harmful pathogens.
They had researched other air purification systems, but they did not clean surfaces or offer continuous instant protection against contaminants brought in to the Surgery.
Our Sales and Support Team worked closely with the Surgery to design an Air Purification Solution that met their needs. Incorporating the latest technology, the Airius PureAir Series was specified for installation in each of their Dental Theatres and patient waiting room.
The units were simple to install over the course of 1 day and now provide the client with safe, clean air, eliminating up to 99.99% of all harmful Viruses, Germs & Bacteria.
Since installation Harewood Dental Surgery have reopened and the results have been fantastic. Not only are the staff happy that they are protected with the latest in air purification technology, but patients are also reassured by the fresh purifying aroma from the PureAir system’s active cleaning agents in the air:
How does the PureAir Series PHI Cell kill bacteria and viruses in the air and on surfaces?
The PureAir Photohydroionisation (PHI) Cell, manufactured by RGF Environmental, one of the worlds leading specialists in air, water and food purification, is a kind of UV light that emits advanced oxidation plasma. Included as part of a fan system, the PHI cell distributes hydro-peroxides, superoxide ions and hydroxide ions throughout the space, neutralising 99% of micro-organisms in the air and on surfaces.
PHI cells produce a group of oxidants known as hydroperoxides. Far from new to our world, hydroperoxides have been around for 3.5 billion years – and today they are commonly used in food processing environments, where they offer an anti-microbial treatment without leaving chemical residues.
Choosing an Airius PureAir Series destratification fan with its integrated PHI Cell is a simple way to reduce bacteria, viruses and odours in your environment.
Multiple studies have been conducted on RGF PHI Cell technology and they are widely approved for use to control airborne and surface-based bacteria, viruses, smoke and odours.

British Airways Engineering is the aircraft maintenance subsidiary of British Airways, which provides support services to British Airways and many other airlines. It is responsible for the entire BA Boeing 747-400 fleet maintenance, cabin interior conversions and general ramp maintenance work for both their own fleet and other airlines.
With the typical high ceiling in British Airway’s East Penn maintenance hangar at Heathrow Airport, the expensively heated air was immediately rising to the ceiling and gathering where it was not required. This in turn increased the temperature difference from inside to outside, resulting in accelerated heat loss, increasing heating costs and an uncomfortably cold environment for employees.
To create as much air movement as possible and working with the leading contractor Gratte Brothers Group Ltd, BA invested in the uniquely patented Airius technology to balance temperatures, improve comfort and reduce costs within the hangar. The 27 destratification fans installed immediately improved the environment even before the heating/cooling system had been upgraded, simply by circulating the heated air supplied from the existing HVAC system more efficiently, reducing load, run time, costs and energy.
“Following severe temperature problems being experienced in a British Airways maintenance hangar at Heathrow, we (Gratte Brothers) were awarded the contract to upgrade the heating and ventilation system along with other M & E works. The temperatures problems were severe with staff threatening to walk out. After exhaustive research, it was decided to install 12 x Airius Model 100 units and 15 x Airius Model 60 units to improve internal air circulation and reduce the extremely high heating and cooling costs. The Airius fans made an immediate and significant improvement even before the heating/cooling system upgrades had been completed, so much so that all complaints from staff ceased immediately and they were now comfortable enough to work in their t-shirts. The team at Airius were really helpful and a pleasure to work with. We will be tendering for further British Airways projects of this type and fully expect to purchase more Airius units.” Joe Forge – Contract ManagerGratte Brothers Group Ltd

Trinity Grammar in Sydney wanted to fix the overheating in their sport hall across the summer period. Viewing crowds and players suffered from overheating in the thirty-year-old hall.
The hall contains two basketball courts and as well as rows of upper level bleachers.
Trinity had considered air conditioning but the extremely high purchase and running cost was out of reach. Then they considered large bladed fans but found them too imposing and also very expensive. The layout of the roof structure also meant that large bladed HVLS fans would have to project significantly down into the playing area, creating a range of other issues.
After hearing about the efficiency and simplicity of the Airius fan solution, the school’s Facility Manager, Ben Morrisey, contacted Airius to provide a simple cooling solution.
He advised that ‘the heat in the gym was very unbearable in summer for students PE, volleyball, basketball and the other indoor sports we play.’ They really wanted air movement and the cooling effect that will bring.
The building is approximately 9.5 metres high and is around 1,000 sq. metres in size. On the upper floor five rows of bleachers are located to look down upon the courts. The school received regular complaints from the viewers seated on the bleachers, that is was also overly warm and uncomfortable up there too.
The School installed 8 x Airius model 60 EC fans in the sports hall, suspended off the roof, (controlled by two Airius potentiometer speed controllers) hidden away above the roof beams and 5 x Airius 20EC Standard Retail Series fans (controlled by one Airius potentiometer speed controller) laterally located above the bleachers to push the air along the seating zone.
This install took place in June 2018 and right across the extremely hot 2018-19 summer period, the school found the Airius Fans very effective in providing air movement and the related cooling impact that brings.
Ben advised after the install he found ‘the Airius fans are small and compact and made a massive difference to their boys in their play in these hot conditions.’
Gama Aviation approached Airius to help reduce the energy consumption in their main engineering hangar at Farnborough Airport, which resulted in a saving of over 48% on their heating costs after installation of the Airius system.
“Gama Aviation are always looking for new initiatives and technologies to help reduce their energy consumption. Not only to reduce costs but also to adhere to new legislation and contribute towards creating a sustainable future for all, and the Airius system has been an effective solution towards helping Gama Aviation achieve those goals.” Sean Hull (Engineering Operations Manager)

As a leader in the retail industry the Parquesur Shopping Centre already had strict safety and hygiene measures in place to protect their occupants and provide the highest quality retail experience.
But in response to the COVID19 pandemic the Shopping Centre wanted to take another step forward in ensuring the health and well-being of its staff and customers and turned to the Airius PureAir System for the solution.
For this application the PureAir PHI Series was specified, with units being installed near entrances and exits, as well as within the high traffic spaces. This offered protection at areas where new contaminents would be brought into the building, as well as providing air and surface decontamination in spaces where there are usually high numbers of people. Following installation the Centre was awarded Global Safe Site certification granted by Bureau Veritas for compliance with good prevention practices.
“Parquesur’s main commitment has always been to take care of our staff and clients. Today, thanks to our solid commitment to innovation, we have cutting -edge technological solutions, such as the new PureAir system to guarantee the highest levels of safety and hygiene in our centre.
Thanks to everyone’s efforts, today we can tell our customers that we are the safest center in which to make their purchases.”

Siemens Transportation Systems Ltd. contacted Airius to address the high energy costs in their Acton Rail Maintenance Shed, which was unable to reach acceptable comfort levels for staff despite the heating running continuously.
Following installation of the Airius system desired conditions were easily achieved and maintained, yet the workload from the HVAC system was also reduced, so much so that the system paid for itself in under 18 months.
Warehouses are large spaces and often have issues with overheating in summer.

The use of air movement for cooling by moving the air across the skin and causing evaporation has been used for centuries in all sorts of tropical and temperate climates. It is a cost-effective solution to the overheating problem experienced in many building types.
“At 35 Deg. C and humid it was really good. We had the fans at speed level 3 in the morning but at 1pm it was too hot so we turned them up to 5 and it was really good – even though it was humid.” Heather, Line Worker – Lush Cosmetics.

“We were pretty surprised by how good they have been…the biggest success is in shooting down the picking aisles.” Alex, Digital Fulfilment Manager – Lush Cosmetics
“We were pretty surprised by how good they have been…the biggest success is in shooting down the picking aisles.”
For the aisles, the units were mounted horizontally just above head height and pointed to blow directly down between the product storage racks.
As a bonus, the units are adjustable in any direction to enable the customer to direct the air flow to where it may be required.
At 7-10 metres high these unobtrusive and quiet units provide a large amount of air flow all across the space with full controllability offered in five settings from 0-100%.
The air movement offered cooling of the inhabitants and made the space much more comfortable and usable. There was an instant improvement in comfort inside the space, which was very well received by the employees and management alike.
BT installed 64 Airius model 45 fan units into their Doncaster call centre to improve comfort levels, increase staff productivity and save on energy costs. This performance report shows that with the Airius destratificaion system temperatures are an average of 2.9°C higher at floor level, compared to the HVAC system working alone.
This is achieved by recirculating the warm air that accumulates at ceiling level above the HVAC air intake. This will also reduce the buildings overall heat ol ss.
The results of this tell us that the thermostat can now be reduced by approximately 3°C to achieve the originally set conditions, thus reducing overall energy consumption and carbon emissions.
With the news of the COVID19 outbreak in March 2020, Mahou San Miguel (MSM) anticipated the impact the pandemic would have on the hotel and restaurant sector and began investigating innovative solutions to purify their spaces.
Thier aim was to provide protection for staff and customers against viruses, as well as reduce mould and odour levels in thier bars.
After researching the wide range of air purification systems available, Mahou San Miguel selected the PureAir PHI system because it provided both air and surface disinfection and had been tested and certified to neutalise the SARS-CoV-2 (COVID19) virus.
The system also significantly improved airflow circulation, drying spills quickly and balancing temperatues, reducing HVAC costs.
The effect of Airius PureAir Home Series may be invisible, but the results are unmissable:
The PureAir PhotoHydroIonisation (PHI) Cell is a kind of UV light that emits advanced oxidation plasma. Included as part of a fan system, the PHI cell distributes hydro-peroxides, superoxide ions and hydroxide ions throughout the space, neutralising 99% of micro-organisms in the air and on surfaces.
Choosing an Airius PureAir Series system is a simple, cost effective way to reduce bacteria, viruses and odours in your environment.
Adding an Airius PureAir Home Series air purification, infection and odour control ventilation fan is a simple way to continually clean the air, creating a safer and healthier environment for you, your family and your home.
Supermarket operators and HVAC consultants have been trying to resolve the problem of customer discomfort in cold chiller and freezer aisles for many years. This problem is compounded when temperatures throughout the rest of the store can be uncomfortably warm in comparison. Costly and inefficient ducting systems, under cabinet heaters and heat retrieval systems have failed to solve the problem to date.
Mitton Mechanical, a Morrisons contractor, approached Airius to conduct a trial in the Morrisons Knottingley store in Wakefield. Airius units were placed at 4 metre intervals in three chiller aisles, reducing stratification from 6-8ºC to 1-2ºC, thus making the chiller aisles more comfortable (without affecting the chiller units). This increased customer browse time and aisle spend, as comfortable shoppers browse for longer and spend more. The system also helps dry spills quickly through evaporation and eliminates glass “fogging”, keeping cabinet products clearly on display.
The trial was hugely successful and over 400 Morrisons stores have now been retrofitted with the Airius units. The Airius system is now on the standard specification list for all new Morrisons stores and will be retrofitted as part of the normal refurbishment program.
Morrisons and Mitton Mechanical are a pleasure to work with. Their eagerness to reduce energy consumption and improve comfort levels for their customers puts them at the very top of the Green supermarket list, which is why they were the first supermarket in the UK to be awarded the prestigious Carbon Trust Standard for making real reductions in their carbon emissions and energy usage.
During the summer months temperatures in Northern Queensland can hit highs of 35°C and humidity can rise to as much as 80%. This can have negative consequences on most building environments, especially those with little or no airflow circulation. Even those with a designed or ad hoc cooling solution can fail to achieve sufficient levels of cooling in these conditions.
This was the situation the Management at The Ramada Hotel Port Douglas found themselves in. In an attempt to resolve the severe over-heating issue the hotel was experiencing in its Reception area the Hotel had installed paddle fans above the counters.
Not only did the paddle fans prove ineffective at providing cooling or circulating sufficient airflow during extreme temperatures, but even during average conditions they were not providing any benefit.
Following discussion with the team at Airius the Hotel Management agreed to trial a single Airius Narrow Aisle unit behind the counter to see if Airius could resolve their over-heating problem.
Not only did the paddle fans prove ineffective at providing cooling or circulating sufficient airflow during extreme temperatures, but even during average conditions they were not providing any benefit. Not only did the paddle fans prove ineffective at providing cooling or circulating sufficient airflow during extreme temperatures, but even during average conditions they were not providing any benefit.
The trial was such a success that within a week the Hotel had ordered another 4 Narrow Aisle units to install in their Reception area.
The units were installed within only a few hours, positioned above each work station along the counter. Each unit was then angled to supply airflow and cooling direct to both staff and customer when at the Reception Counter, providing the much needed and long awaited relief the Hotel has been looking for.
Howard Gumbley, General Manager at Hilton Brown’s Pools contacted Airius to address severe condensation problems in two of their swimming pool facilities in Albany and Havelock North.
At their Havelock North site condensation was impacting on the main pool area, whereas at their Albany pool condensation was causing problems in the main pool and changing rooms.
Both building interiors were constantly damp, benches were wet and water would drip on spectators, especially on cold days. Anything metal or mechanical was particularly affected; locks and automatic doors were jamming and rust was uncontrollable, even on galvanised metal. Being constantly damp, the concrete walls became discoloured and paint deteriorated rapidly. Mould and unpleasant odours were also large problem.
For the Albany pool, which measured approximately 20 metres by 12 metres, the Airius Standard Series model 60 was specified. In the changing room the smaller Standard Series model 15 was recommended.
“Within hours we noticed a difference. Two days later the entire space was a lot drier, with less damp odour. We had spent vast sums of money installing mechanical air handling units and ducting systems in this space, but there were still areas where instructors and customers found it very humid.
“Air quality dramatically improved. The glass viewing wall was constantly fogged up prior to installation. Within a day there was virtually no condensation on the glass and the concrete area around the pool dries out much faster than it did before the units were installed. The units are simple to install and very economical to run, but above all they deliver results.” Howard Gumbley – General Manager (Albany)

“The Airius system not only alleviated this issue, but helped dry out an end wall that was often wet with condensation.
We have since installed other Airius units in more of our facilities.”
The Havelock North pool, due to its sloped roof, required Standard Series model 25 and 15 units, to account for the variation in height. At its highest point the ceiling was 4.8 metres and the pool measured 24 metres long by 14 metres wide.
After installation both sites virtually eliminated all condensation. Any signs of damp quickly subsided and surfaces dried much faster. Even the concrete, which had become saturated and discoloured, dried out. Comfort levels vastly improved and within only two days the unpleasant odours were almost non-existent.
In addition to resolving the main problems with condensation, Hilton Brown Pools also achieved significant pool heating energy savings at both their Albany and Havelock North pools, benefiting from Airius’ world-leading thermal balancing technology.
In the REMA 1000 store on Skovvej in Korsør, new solutions were being investigated to cut food waste and reduce the amount of fruit and vegetables being discard to optimise earnings.
Staff and customer protection was also of paramount importance amidst the SARS-CoV-2 pandemic.
In October 2020, the REMA Skovvej store installed two Airius PureAir fans in their fresh produce, bakery and florist department in order to protect their fruit and vegetable stock.
The PureAir fans are equipped with cutting edge ionisation technology, which neutralises up to 99% of all bacteria, viruses and moulds.
“The result is surprisingly good! Fruits and vegetables stay fresh for 1-2 days longer than before”, says grocer Jørgen Nordtorp, who runs the REMA 1000 store in Skovvej. “In this way, the fans contribute to both reducing food waste and making the store more green.” REMA 1000 are now in discussions regarding installation of the PureAir system throughout the rest of their stores.
Usually fruit and vegetables are stored in cold rooms overnight and replaced the next morning in Danish grocery stores, due to poor air quality in the store rooms. But, with Airius PureAir fans this is no longer necessary. Easily installed in the ceiling the PureAir system also provides constant air circulation, balancing temperatures and improving comfort significantly.
“The air has simply become fresher, so now we do not have to drive most of the fruit and vegetables in and out of the cold storage every day, and thus we save a lot of time”, says REMA grocer Jørgen Nordtorp.
“Especially for sensitive vegetables such as cauliflower and broccoli, we are experiencing a doubling in shelf life. But even for coarse vegetables, there is a clearly longer shelf life”, he explains.
Jørgen Nordtorp is also looking forward to the upcoming strawberry season with fresher products and better shelf life. The strawberries can withstand poorly changing temperatures and storage in a cold room overnight. This often results in a very large discard of the red berries.
With the Airius fan installed, Jørgen and his team of staff no longer have to handle goods in and out of overnight storage and as a result have saved at least 20-30 minutes of labour time on a daily basis.
“We save a small hour a day, because most fruits and vegetables are no longer refrigerated overnight. It is a relief, especially because it is typically inexperienced employees who would otherwise have to carry out the work during the evening”
Jørgen Nordtorp – Store Manager
Under normal winter heating conditions the temperature in the Volkswagen showroom at high level was measured at 32ºC and at low level 18ºC.
This stratification effect can be seen in this illustration and is very common in buildings of this nature.
The Airius destratification fan system was installed giving a much more comfortable even temperature throughout the area.
Following installation it was also noted that the heating, which normally ran all day trying to reach it’s set temperature, would switch off by midday and not start again until after 4pm.
Celtic Manor contacted Airius to provide a solution to improve comfort for occupants in their glazed Cen Restaurant and Bar. In summer it would act like a greenhouse and result in uncomfortably high temperatures, whilst in winter the heat would escape before it reached comfortable levels.
They also needed to reduce the exorbitant heating and cooling costs from a continuously struggling HVAC system.
Each area was also fitted with its own variable speed controller to manage fan speeds from season to season.
Following a free survey and detailed floor plan review a system comprising of Airius Standard and Designer Series fan units were specified throughout the Cen Restaurant and Bar area. Units were positioned in line with the clients floor plan and a selection of units were custom painted to blend in with their surroundings.
Celtic Manor were very satisfied with the results of their installation and found conditions in both the Restaurant and Bar areas vastly improved within only a few hours of the system being turned on. They have also since noticed a significant annual reduction in their energy costs.:
Newmarket Motors needed to resolve the uncomfortably high temperatures experienced on their first floor and the uncomfortably low temperatures found on their ground floor, which were creating unsuitable conditions for their staff to work in.
The Airius destratificaion system was simple and quick to install and not only resolved the temperature imbalance, but also highly reduced the output, workload and operating times required from the A/C system offering significant savings on their energy costs.
“The owner had expressed he was having problems with uneven temperatures between the upstairs offices and downstairs offices and showroom. Staff upstairs were too hot and the staff downstairs were working with their coats on at times. The Showroom has 3 sides of glass, floor to roof. They have 4 combined heating/cooling units with the temperature set at between 30 – 33°C with 4 blowers set to maximum. We installed 3 Airius Model 25’s. The temperature on the A/C units have now been reset at between 18–22°C with the 4 blowers on the low setting and 2 of these are turned off intermittently for approx. 2–4 hours per day. Staff on both floors commented on the lovely comfortable temperature in comparison to before the system was fitted. These have been monitored during the cold spell of weather that we are experiencing at the moment.” Sean Browne – Dealer Principal

Maintaining a clean, safe environment for patients and staff during the COVID19 pandemic was a top priority for Dobrich hospital. Patient to patient transmission needed to be controlled, whilst medical staff were in desperate need of protection when performing emergency surgeries on COVID positive patients. Due to budget restraints and no HVAC system within the building sourcing an easily adaptable solution was critical.
After conducting their own in-house tests, the Hospital was so impressed with the results of the PureAir PHI system they immediately installed units within their Orthopaedic department. As units can be installed within a matter of hours this caused minimal disruption to the normal operation of the building. The system was later extended to include their Surgical and ER departments, as well as other high traffic areas.
Directors, staff and patients have been extremely impressed with the results of the PureAir PHI system:
Foodie’s first installed 8 Model 15 Airius fans in its 745m² store in South Boston. Managers were so pleased with how the destratification fans warmed up the store for both employees and customers that they installed another system of 7 Model 15 fans at their store in Duxbury.
“Before the Airius fans were installed at the Boston store, employees, especially checkout clerks near the store entrance, complained about being cold,” said Michael Stameris, Facilities & Operations Manager for Foodie’s.
“After the fans were installed on each side of the checkout lane and throughout the store, clerks told managers they now were too warm!” Stameris explained. “I lowered the temperature in the store. But on the next day, they said they were still hot, so I lowered the temperature a second time.”
Another factor that led Foodie’s to the Airius system was the fan’s low use of electricity and easy plug-and-play installation. “These fans really use a small amount of current,” Stameris said.
Store managers, using a thermal scanner, could easily see the temperature difference between the hotter ceiling area and the store’s cooler floor. “With the recent cold winters some customers also complain about being chilly,” Stameris said.
With ceilings of about 4 metres in South Boston and a range from 3.5 to 5 metres at the Duxbury location, the Airius Model 15 has worked well at circulating hotter air to the floor.
Foodie’s also installed fans above its open case frozen food aisles, where managers believed that cold air was spilling out.
“We were pleased to find that the column of air is so pinpoint to the floor that we could install the fans less than a metre off the centre of the open cases,” Stameris said. “It’s very precise.”
At Foodie’s Duxbury store, one manager’s office is located on an elevated mezzanine area. “That office area was often too warm, while employees on the floor below the mezzanine were too cold”, Stameris said.
Three fans were installed along the ceiling in the elevated area, to draw the excess heat from the high level office area and recirculate it down to the floor below to solve the problem.
“Groceries, with frozen food aisles, open refrigerated cases and entrances frequently opening and closing for shoppers, make it tough for managers to keep thermostats at their set points and are an anomaly when it comes to keeping temperatures balanced. But the Airius system has helped us do just that, saving a lot of money” Stameris said.
“I’m a believer in the Airius system,” he adds, “I’ve seen first-hand how it has helped.”
Springfield Central State High School is an Independent Public School (IPS) with students from years 7 to 12. It is located out towards Ipswich, west of Brisbane.
It is a relatively new school with the library around 3 years old. The library staff and students complained about the overheating in the space during summer. There were large extraction fans installed that proved very ineffective and noisy.
The school had looked at the typical solutions including air conditioning and HVLS fans. Neither of these options were either cost effective or visually suitable. They required a low cost, unobtrusive, aesthetic and quiet solution.
Airius provided a complete design, supply and install solution.
After much consideration, the school proceeded with the Airius solution. The results speak for themselves.
The installation looks great, offers excellent, controllable and cooling air movement throughout the space and is very quiet.
The units use between 30 watts each at full speed and when run at half speed use around 12 watts. At low speed, just ticking over, they use around 5-6 watts each.
Their non-turbulent, laminar flow directional and controllable, low noise and patented air delivery design is perfect for the library environment.
St. Thomas Aquinas School in Bowral has installed 8 Airius thermal equalisers to serve a newly constructed school hall with a ceiling peak of 6.7m.
As part of the BER schools project, Martin O’Toole Architects chose the Airius system as advised by sustainable consultants from Vento and Vim Sustainability.
The technology was chosen as a cost-effective solution to ensure that the building reduced its heating bills and carbon emissions.
Andrew Lowden, the project architect said, “The Airius thermal equalisers are a great asset to the school hall. The main benefits for the client include improved air circulation, a balance of temperature throughout the building, low running costs, silent operation and easy installation – all at a highly affordable price.”
Andrew underwent a site visit to test the units in 2011, when outdoor temperatures in Bowral did not exceed 12⁰C.
“The hall’s gas heating system warms the hall effectively within 15 minutes. However, to maintain this temperature for long periods of time would be cost prohibitive to the school. This is where the Airius units come into play. Once the hall is occupied, the gas heaters are turned off, leaving the Airius units running to circulate the warm air. When the Airius system was turned on, a constant temperature between 18-20⁰C was maintained for a period of time” he says.
James Idle, the Senior Design Engineer at Vento had designed the destratification solution to ensure that the warm air generated by the gas heaters would be distributed evenly throughout the building. “The aim of the Airius system design was to reduce the workload on the existing HVAC system, allowing the end user to save on their gas bill”.
Andrew confirms that his client was on a tight design budget, however the Airius units were highly affordable, and gave an attractive payback period and cost savings against the school’s existing gas and heating bills. “I would highly recommend the Airius solution for my future projects.”
In preparation for reopening after the COVID19 pandemic lockdown and to be among the first to provide their guests with the new standard in building air quality systems, the management team at Casa Salegueiro made plans to invest in an air purification solution. They also wanted to find a solution that would improve air circulation and provide cooling benefits in the Portuguese climate.
After reaching out to the management team, Airius visited the clients venue to carry out a free site survey and system specification. PureAir units were specified for installation in each of the function rooms, which were fitted by the clients contractor within a day. Units were positioned to provide optimum purification coverage and airflow movement, but without causing uncomfortable draughts.
The management team at Casa Salgueiro have been extremely impressed with the results from their new PureAir system:
Not only are the management team confident that staff and visitors are now protected from COVID19 by the Airius PureAir System, but customers have been amazed and overjoyed that they can provide a virus-free space for their guests, adding significant value to the venue’s service and the customer experience.
In addition, the airflow movement supplied by the PureAir fans, which can be increased or decreased to suit the season, ensures guests are kept cool in Summer and warm in Winter. This avoids the expensive capital costs of using an equivalent air conditioning system.
Casa Salgueiro’s PureAir installation even gained the attention of nationwide news program, ‘Jornal da Tarde’, who supported the use of the Airius PureAir system in the battle against COVID19.
Toyota Kilmore is a new architecturally designed car showroom located in the region just north of Melbourne. The area suffers from very hot summers and very cold winters.
After seeing the units in operation at a large retailer in Melbourne, Graeme approached Airius to provide an air circulation and destratification fan solution for his Showroom facility, to improve the efficiency of his air conditioning system in both summer and winter, while also optimising the thermal comfort of his customers.
The facility is around 500 sq. metres in size and approximately 6.5 metres high.
Graeme wanted the unique look of the latest Airius units and he opted for the recently released Retail Series to be installed at his Showroom in Kilmore in late 2015.
These aesthetic, high performing, very quiet units, primarily designed for a broad range of retail applications, offer a unique solution without the constraints of other types of fans and suit the facility very well.
Airius satisfied the customer’s every concern.
In summer, the higher speed circulation capability offers cooling on its own or optimises the performance of the air conditioning system.
In winter, the penetrating ‘Torus’ air flow shape of the patented Airius units, ensures rising heat is not wasted and is efficiently pushed back down to the floor.
Graeme purchased 12 Airius Retail Series units with speed control capability and installed them under the ceiling in his showroom.
The units are simply suspended off the ceiling structure above and work silently to maximise the circulation of cooled air in summer, as well as provide cooling with the air conditioning turned off, and save heating energy in winter while.
Graeme is thrilled with the look and the performance of the units and excitingly for him, this was the first commercial installation of the new Airius Retail Series units in Australia.
After a number of consecutive hot Summer seasons, The Boathouse Tavern reached out to Airius to advise on a cost effective cooling solution to keep their customers cool in high Summer temperatures. In the Winter the tall ceiling above their internal boat attraction would also act like a heat sink, drawing warm temperatures away from the floor.
The Boathouse Tavern needed a solution to address this, without causing noise disturbance.
After visiting the space and plotting airflow circulation patterns, the Airius Retail Series was specified to provide evaporative and airflow cooling in the low ceilinged bar area.
For the high ceilinged Bar area the ultra quiet Airius Q Series was specified, installed with a variable speed controller, providing high velocity airflow cooling during the Summer, in addition to gently recirculating high level heat during the winter, via use of the speed controller.
The Airius system provided an immediate effect, providing the client and customers with an instant cooling and refreshing breeze in the Summer heat after installation. This equated to a 32% saving on their cooling bills. They also benefited from heating savings in the Winter, reducing annual costs by 25%:
School and community sports centres are large spaces and in the Australian climate often have issues with overheating in summer.
The use of air movement for cooling by moving the air across the skin and causing evaporation has been used for centuries in all sorts of tropical and temperate climates. It is a cost-effective solution to the overheating problem.
In 2015, St. Stephen’s College’s Director of Sport, Rob Seib, approached Airius to provide a proposal to supply an Airius cooling solution as an alternative to large bladed fans.
The two basketball courts were in a relatively new building with high roofs around 10 metres high and around 1400 sq metres in size. Located in a sub-tropical climate, high summer and moderate winter temperatures combined with high humidity are typical for the area.
The building design has limited capacity for cross flow ventilation and suffered from severe overheating in spring and summer. The building is used for both sports and classes and the overheating impacted negatively on both sports performance and learning outcomes.
Airius supplied 12 x Model 60 Airius Standard Series units with two 5 Amp speed controllers, for an installed cost of around 15% cheaper and with greater floor coverage than the alternative large bladed fans.
As a bonus the units are very quiet and are adjustable in any direction to enable the customer to direct the air flow to where it may be required.
At 10 metres high these unobtrusive and quiet units provide a large amount of air flow all across the space. Full speed control capability is offered in five steps from 0-100%.
The improvement in comfort inside the space was instant and the customer indicated that even in the warmest days in the Gold Coast summer the air movement offers cooling and has made the space much more comfortable and usable.
Eden Gardens was struggling to maintain a fresh and healthy environment in their assisted living community.
In particular, their Alzheimer’s unit was losing an average of three residents per month due to dissatisfaction over the air quality or illness, such as pneumonia. This represented a £60,500 loss, or more than 100% annual turnover in residents each year.
The PureAir Series from Airius is a brilliantly simple system.
By adding air purification cells to our patented destratification fans, our customers can reduce airborne contaminants and also bacteria and viruses on surfaces. The fans also eliminate many volatile organic compounds, which creates a fresh-smelling environment without the need for chemical cover-ups.
Eden Gardens were delighted at the results the PureAir delivered:
Choosing an Airius PureAir Series destratification fan is a simple way to reduce bacteria, viruses and odours in your environment.
In the case of poultry rearing sheds, particularly those using gas heating, thermal stratification has a very costly impact.
As hot air rises the roof accumulates the heat first, followed by the main cavity of the building before finally reaching the floor.
As the birds are grown at floor level most this heat is wasted, heating the higher levels of the building before finally reaching the area where the birds reside.
Through the implementation of a destratification system, hot air in the roof is recirculated down to the floor continuously. In this manner, the cleaner, hotter air in the roof is recovered and redistributed to where it is needed at floor level.
This leads to a significant reduction in gas consumption, the greatest non feed expense in rearing birds.
Operational & Environmental Savings
A significant reduction in running costs was recorded for the gas consumption, measuring 35% on average savings. An additional benefit is the savings in Carbon Emissions. It is estimated that implementing the Airius solution in poultry shed saves up to 21.8 tonne of C0₂ annually.
Energy Consumption
All Airius systems are manufactured with energy efficient motors designed to offer significant savings, with negligible running costs. The units specified for this project operate at only 17.4 Watts each.
The unit’s motor housings are sealed preventing dust and other contaminants from damaging the inner components, ensuring their ability to operate smoothly in the harshest conditions of the Poultry shed environment. This unit is also specifically designed to mitigate any bio-security concerns and meet the highest industry standards as defined through consultation with leading industry vets.
The solution is perfect as both a retrofit option, as well as for new sheds and can be installed by any local electrician with minimal disruption.
