The problem

Aeroplanes with a pressurized cabin need pressurized air as carrier of cooling/heating for the HVAC-system and in the ice defrost system. The only available pressurized air is from the turbines. The pressure is up to 10 bar/150 psi and the temperature is up to 350°C/660°F. The problem requires not only an efficiency of up to 99% with limited air as cooling medium, but also that the heat exchanger must be compact, mechanically strong and most important: have a low weight.

The solution

As AirCross 21 offers dramatic advantages, our heat exchanger is a key component in many projects for small and medium jet turbine planes. Size and weight is reduced up to 80% and efficiency is increased from typically 60% up to 99%. In our most prestigious project, Eclipse 500, several tests were required as they did not belief the excellent performance with AirCross 21. In another project the test pilots refused to fly until the planes were equipped with AirCross 21. AirCross 21 is FAA-approved.
