Whether it be a private or commercial aircraft hangar, maintenance hangar or even airport terminal, Airius destratification fans balance internal temperatures to significantly improve occupant comfort and reduce heating and cooling costs by up to 40%.

By equalising temperatures and recirculating rising heat back to the floor, Airius fans reduce turnaround times, speed up daily processes and reduce maintenance downtime. Most importantly, your employees and visitors will be consistently comfortable all year-round.

We all know heat rises and the higher the ceiling the more heat is wasted, filling the unoccupied space above occupant’s heads. Hangar and terminal HVAC systems try to overcome this by constantly pumping warm or cool air into the space in an attempt to achieve thermostat setpoints at floor level. In aircraft hangars, terminals and aviation buildings, which can reach 40+ metres high, this heating of the void can represent tens, if not hundreds of thousands of pounds in heading costs.

Airius destratification fans resolve this problem by slowly recirculating rising warm air back down to the floor in a slow moving, invisible column of air without creating drafts. This continuous air recirculation creates a uniform and even temperature throughout the space from floor to ceiling. This enables thermostat setpoint to remain the same, but heating and cooling system do not have to work as hard to maintain it, significantly reducing both running costs and energy consumption.

baBritish Airways – East Pen Hanger (Heathrow)

“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.”

We have installed Airius destratification fans into hangers at our Blackbushe Airport, Surrey and Oxford Airport sites with great success. At both facilities Airius fans units have made the working area much warmer for our aircraft technicians and the heaters are switching off a lot more often which has never happened before.”

Gama Aviation

“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.”

Avalon Aero

Having recently installed the Airius destratification fans into our aircraft maintenance hangar facility at Biggin Hill Airport, Kent, UK the increase in temperature to the working area on the hangar floor area was noticed immediately. The units were simple to install and the team at Airius were supportive throughout. I would have no hesitation in recommending their system to operators of similar facilities.”
