Testimonials, Airius, UK
Airius units have been installed in many government and public buildings including; schools, museums, recreational and sports centres, swimming pools, theatres, military installations, fire stations, courts and even prisons.
Commercial Installations include; aviation, transportation facilities, distribution centres, electrical and mechanical contractors, energy service companies, engineering and manufacturing facilities, retail outlets, hospitality areas and restaurants and marine facilities.
Our Edinburgh Outdoor Experience store has a single floor store layout opening out into high roofed area with a ground floor café and gallery sales area; this open space had two issues; the gallery space being too hot during the summer months whilst the ground floor café was too cold for customers during the winter months. We originally controlled the temperature with large AC units but the result was never satisfactory at either level. We installed 5 Airius destratification fans moving air from the high level on the gallery and pushing it down to the ground floor level, this brought the temperature on the gallery down to a comfortable level during the summer and resolved the cold customer issue in the café throughout the winter. The Airius system was installed during the summer whilst the AC system was closed down for servicing and we were happy to find the environment now comfortable without the AC running. We were interested in the destratification effect during the winter months, as part of some trials we shut down the AC heating system and tested several thermostatically controlled wall heaters and found the temperature across both levels more than satisfactory with the temperature well balanced. This has now led to the entire AC system being decommissioned with a considerable reduction in electricity consumption. We now consider destratification systems as a key part of our refits and store design for new openings, this helps us achieve improved customer comfort, operating efficiency and contributes towards reducing our carbon emissions.

Since fitting the airius destratification units in our storage warehouse we have been able to keep a constant temperature and are also able to switch one of our heaters off thus giving us a saving in heating costs.
Paul Stewart - Safety Health & Environmental Manager
In September 2008 we installed nine Airius destratification fans in our distribution department. At the same time we also installed two high efficiency space heaters as replacements for existing heaters. Prior to these changes, in winter the difference between temperatures at floor level and roof level was approximately 5/6 degrees C. The difference now is approximately 1/2 degrees C and this has resulted in a reduction of approximately 25% in our gas consumption between October `07 to March `08 and October `08 to March `09.
As you can imagine we are very pleased with the outcome.
We are a very small rural church with an ancient oil-fired heating system. The spiders living in the apex of the roof were very cosy but the congregation was freezing. We had recently had a big fund raising for repairs and thus were looking for a cost effective means to improve the distribution and utilisation of the heat generated by the antiquated system! Airius fans seemed to be a possible solution. We have now gone through our first winter with the fans in place. The temperature in the church with the fans running is more even, the church feels warmer now that we "harvest" all that heat in the roof and the fans are very economical to run. We have kept the congregation from freezing and managed to reduce the boiler burning time by about 25%. We think the Airius product speaks for itself.
In regards to the Airius units fitted, they have proved a great success by balancing the heat profiles in the large office area’s, particularly with the top floor, where the ceilings are very high. The complaints of cold spots have ceased. It has allowed the cut off temperatures to be controlled at a reduced level and may allow a further reduction still for the next heating season. As mentioned, we had an audit by Carbon Trust and whilst the electric heating we have at Fazeley was not classed as efficient, the surveyor carrying out the audit acknowledged we had taken as many practical steps as were possible by the use of start up controls, temperature control and the Airius units to make the best use of the heat the system produced. It is envisaged we will be installing further units where we know we have a need to bring the warm air back down from the high ceilings for the benefit of those sat at floor level!! I am still investigating the electricity use savings, but this will have to be done by unit consumption, rather than cost with the increases we have all sustained in electricity prices, it is difficult to determine by cost. I’ll keep you advised of the outcome.
McLaren Plastics recently installed 8 off Airius model 25 units in their moulding shop which operates 24/7 producing injection mouldings for the engineering and packaging industries. The operators in the area soon appreciated the more pleasant and balanced working environment as the heat that used to build up in the ceiling area was pushed down by the Airius units and re-circulated. As a company operating under the present marketing conditions we welcomed the reduced gas consumption and the consequent reduction in our carbon footprint that resulted from this investment. We would also acknowledge the support we received from Loan Action Scotland with this project.
Here is a comment that we received from one of our tenants who is happy with your product. “The destrat fans are very quiet and have not inhibited our daily work in any way. They have proved to be successful by pushing the warm air down, definitely providing us with a more constant temperature throughout the whole floor area”.
We installed the units throughout the Machine shop, Fabrication Workshop and Mechanical fitting department. The units arrived on schedule and were installed with great ease using a local electrical contractor. Since the installation we have had a warmer more constant temperature in the workshops and many comments form the machinists stating that the air temperature is better for working in. The thermostat fitted to the heaters has also been turned down and thus giving us saving on fuel used. Overall a very good investment.
We would like to thank you for the Airius units that we use in our Printery Reel Store. As in common with all web offset printers we have found a problem with paper being too cold when delivered in winter and causing webouts in the printing process - an expensive waste of time and resource. The Airius units have proved extremely helpful in solving this problem. We are pleased with the quiet running nature of the fans, the fact that they are small, unobtrusive and yet so useful.
We have found the Airius fans to be a great asset to the working environment of our 12,000 square foot factory. Prior to the installation of these units the mezzanine areas were unbearably hot and the ground floor was at best cool. However, since the installation the working environment in both areas has become much improved.
"I confirm my order for a further 4 x model 25's for use in our Tonbridge branch. The staff in Folkstone are very happy with the performance of the units there, the thermostat has been turned down way beyond the point that I thought was humanly possible! I will put pen to paper and write a letter as a satisfied customer."
Since we installed the Airius units in our Grade II listed Bourton Hall this winter we have noticed a significant increase in temperature when we open the building in the morning, requiring fewer inefficient, local space heaters on the ground floor. We also installed a unit in our unheated storage building and it has made a difference there as well, noticeably taking the chill off and providing the necessary ventilation without penetrating the roof structure.
Further to our telephone call I can confirm that we are very pleased with the 2 installations of Airius fan units. * Installation 1: Installation of three Airius fans (Model 35) in main workshop area in November 2008. We have quantified our savings based on last year gas bill and have saved approx £500.00 on the quarterly bill. * Installation 2: Installation of two Airius fans (Model 15) in new canteen area. Units have only been running approx 3 weeks and we hope to generate similar savings. As discussed earlier I am more than happy to show the installations to any new customers.
The Airius destratification units installed on the shop floor of our Bath site are very effective. The units have been instrumental in bringing down hot air trapped in the ceilings and high roof areas of the shop floor. Heat generated is better circulated around the building and the staff on the shop floor are of the opinion that the overall warmth inside the building has increased. Airius have made it possible to provide better heating without installing new heaters and without increasing temperature levels on existing heaters.
We installed 34 Airius number 35 free hanging units into the can assembly plant at our manufacturing site and I am very pleased with the results so far. The heating system in the building now comes on far less than it used to and the employees who work in this building are now much warmer. I am currently collating data as to exactly how much heating oil we are saving which even at this early stage I am sure will be substantial. Once I have this data I will be looking at other buildings on our site and also recommending Airius fans to other companies within the group who operate from many large buildings throughout Europe.
"We installed an Airius Destratification System in our PVC Window Manufacturing Unit over 12 months ago. The unit has 6m eaves with a ground floor area of 12500 ft2. Prior to its installation the gas powered space heaters were running throughout the working day in the winter months to maintain the air temperatures required by the production unit. Ground Floor Temperatures were cool but temperatures at mezzanine level to which the warm air had risen were warm. Hence the continuing output requirement from the heaters. In the period following the installation, the air temperature zones were reversed with warm ground floor temperatures and cool mezzanine level temperatures. The heaters therefore were running less frequently as they are linked to a thermostat 2m from ground level. The result is lower heating consumption, a warmer working environment and a happier workforce. "The Airius system does what it says on the tin."
VW Showroom - Newmarket Motors Ltd We surveyed the VW Showroom as the owner had expressed that he was having problems with the 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 A/c units with the temperature set at between 30 – 33o with 4 blowers on to maximum. We recommended that 3 Airius Model 25 units be fitted throughout the showroom, directly facing the floor and away from Air Conditioning Units. These have since been fitted and we are awaiting the Electricity bills to show definite reductions. In the meantime, the temperature on the A/C units have been reset at between 18 – 22o 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 heat in comparison to before these were fitted. These have been monitored during cold spell of weather that we are experiencing at the moment.
The installation went well and all parts required to do the work had been delivered." "The installation went well and all parts required to do the work had been delivered. As soon as the units had been installed the workforce commented on the difference in workshop temperature. The heating system we have in place was then turned down and used less often. The Airius units circulated the air and kept a more even temperature in the workshop. We have the units fitted in the Machine Shop / Fabrication Shop and Mechanical Fitting Area. It has been a good investment and works well.
We purchased 10 Airius number 35 free hanging units to install into a sports hall and swimming pool at the Sixmile Leisure Centre, Newtownabbey. These units have made a vast improvement to the internal atmosphere within the building and the public who use the facilities find the air quality greatly improved for sporting activities. We have also found that the Airius units have reduced our heating costs by an impressive amount.
Thermal Imagery of Controlled Temp Warehouse The accompanying thermal images were developed from the temperature controlled warehouse of a major pharmaceutical company. The company’s new 50,000 sq ft warehouse facility in Louisville, KY did not pass the Food and Drug Administration’s required Temperature Validation Tests with the originally designed HVAC system. As can be seen in the ‘Base Case’ image without AIRIUS® fans, the top levels of the pallet racking were exposed to 73°F 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 starting over with a re-designed system. A senior facility engineer had been told of the AIRIUS Thermal Equalizers® by an AIRIUS sale agent and suggested the use of them for this application. The HVAC Contractor was very skeptical that 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 25-120V Thermal Equalizers® 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 Thermal Equalizers were originally developed to de-stratify heated air, and the fact that cold air naturally sinks, it can be seen by comparing the ‘Base Case’ image to the ‘Base Case With 50 AIRIUS Fans Installed’ 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 Equalization! The elevation graphic shows a complete equalization of temperature around the pallet racks supporting literally billions of dollars of inventory from floor to ceiling meeting FDA regulations and approval. This AIRIUS installation allowed the warehouse to pass FDA Validation Testing and helps ensure the safety of the products for the manufacturer and the consumer. It has been reported to Ray Avedon of AIRIUS, LLC that the temperature variance from the bottom of the 18’ racks to the top with the fans running over the last year is only ½ to 1°F This case is a graphic example of how the AIRIUS Thermal Equalizers can work in air conditioned environments as well as heated environments and testifies as to how well they truly do equalize nearly 100% of the air temperature in a given space. The results of this original installation; AIRIUS is now specified in the next two warehouse projects, one in 2007 and another in 2008, for this same pharmaceutical company.
We are very happy with the performance of the AIRIUS units. The space within the county jail stays very comfortable and it is easier to control the temperature…. we have requested funding, to install the AIRIUS System throughout the entire jail, for a 2007 installation. We installed the AIRIUS units in our 30,000 sq ft exhibition building. Again the space seems very comfortable…. There is no difference in the temperature between the ceiling and the floor. I work for local government and it is in my best interest to only use products that represent a rock solid investment….
The AIRIUS product has worked extremely well for us – it has exceeded our expectations. Our main hanger is approximately 32,000 sq ft with 40ft high ceilings. Before adding the AIRIUS products the heat would rise to the ceilings in winter leaving the floor cold. With the AIRIUS products installed the temperature remains constant from ceiling to floor. This has allowed us to reduce our thermostat settings while increasing the comfort level on the floor…. Our employees love it – where they were wearing coats they are now working in t-shirts.
“The model that we purchased was installed by us in house. All we did was replace the existing destratification fans located at the ceiling on one of our large hangars, and replace them with the Airius thermal equalizers. Fiscal Year 2005 (Oct 2004 - Sep 2005) we used 119,033 CCF of Natural Gas for heating that hangar. Fiscal Year 2006 (Oct 2005 - Sep 2006) we used only 77,146 CCF of gas to heat the same hangar, for a savings of 41,887 CCF. If we factor in the average cost of gas for that same time frame ($1.47/CCF), that leaves us with a savings of approximately $61,574 from the previous fiscal year........ there were other factors but without a doubt these thermal equalizers paid for themselves that first year. We didn't get them installed until January 2006 to boot!”
I am the manager-in-charge of the energy service side of Bitter Creek Pipelines. We are the ESCO currently engaged in revamping the energy usage requirements for both Ellsworth and Minot Air Force bases (located in South and North Dakota). Our task and main objective is to reduce energy costs at these facilities. Recently we identified that heat stratification in the hangers at both of these facilities was a main contributor to excess energy consumption. In response, our project team looked at and tested several currently available devices that claim to address and resolve this issue. We found all but one to be inadequate and unable to meet their claims. One such product was the Strato Jet which, when tested, produced not only an excessive level of noise, but also essentially a non-delivery of air.flow. On the other hand, when we tested the Airius product we found that it did everything that it claimed it would do. Basically the Airius product proved to be vastly superior to any other product tested. To date, our company has installed over 900 Airius units at Ellsworth and Minot. In the near future we will be installing several hundred additional units and expand our installation program to other like kind facilities.
The AIRIUS System reduced our energy costs by 26% and paid for itself in one winter season. The units increased the air circulation throughout the planting benches, eliminated non-productive cold corners and increased our winter plant growth. As you predicted, our concrete floors and walkways became a heat storage bank, supplying free heat during the night. As a result of installing your system, the consistent temperature increased our winter plant growth in ways we had never seen before. Calla Lilies bloomed 25% more than in previous winter months and our philodendron showed exceptional growth…. The AIRIUS System helped us grow healthier plants. We’ve now installed the system throughout our greenhouses….
I would like to compliment your company on a fine product. We use your AIRIUS System in our 6,000 sq ft rock climbing gym. Rock climbing gyms present a unique challenge when thinking about ventilation. The climbers do not want to climb in to a hot area whilst their partners at the bottom of the “rock” need to be kept warm…. the opposite to the laws of physics….. we need warm air at ground level with no increase in temperature as the climber ascends the wall. The AIRIUS System is perfect in this application…. they are safe, quiet and very energy efficient and allow us to save on our air conditioning costs.
" Churches are always a problem to heat effectively and economically but on several recent schemes I have found that the Arius range of destratification fans have proved most advantageous in achieving our objective to provide heating schemes for our clients which maintain a uniform temperature within the buildings and prevent unnecessary heat loss through the upper structure. Our designs are based on maintaining a minimum background temperature at all times which can be boosted to normal comfort levels before services and events and then maintained to a major extent during occupation. In our schemes the Arius destratification fans are normally used during the non occupied periods (when the small amount of sound generated by the fans is less of an issue) to evenly distribute the heat delivered from a variety of heat sources thereby maximising their effectiveness. This is particularly useful where there are limitations on the locations for heating terminals which is often the case in church buildings. The Arius units which we have specified have been the 25 suspended range and the 35 range with ceiling kits. The units have been found by our clients to be compact and therefore comparatively unobstrusive when mounted at high level as recommended. Every project is different and requires careful consideration particularly when dealing important and historic buildings, but we have found the Arius equipment to be sufficently versatile to be able to achieve acceptable solutions on several projects. David Gadsdon - Director - Environmental Engineering Partnership - Consulting Engineers"
We installed 4 x Airius destratification fans to balance the temperature in our hot room. Prior to installation we had a 20 degree C temperature differential over the 11 meter high hot room, since installation of the fans the temperature differential has dropped to 4 degree C. The fans are very quiet and have very low power consumption and I would recommend them highly.

Further to our recent telephone conversation, I confirm that it would be in order to use my name as a testimonial in relation to recent church schemes which which I have been involved. Quote as follows :--
