British Airways Reduce Heating Costs with Airius Destratification

Improving Comfort while Reducing Costs & Carbon

Key Points:
  • Significant heating savings
  • Immediate comfort improvement
  • Reduced load on HVAC system
  • Reduced hangar heat-up time
  • Desired conditions achieved without upgrades


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.

British Airways Improve Comfort with Airius Destratification


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.

Airius Destratification Fans Installed at British Airways East Penn Maintenance Hangar


“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.

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).
