The introduction of Air Comm’s "mini-ejector" bleed air heater in 1987 revolutionized helicopter cabin heating systems. For the first time, operators could rely on a single light-weight, low-cost, maintenance-free system to provide ample heat regardless of the operating environment. ACC heaters have been field proven to -40°F and today are found on more than a dozen different types of turbine helicopters operating from Yukon, Canada to Antarctica.

“We have flown in temperatures as low as –30°C (-22°F) for a week. Very cold and very damp conditions. Your heater (Arctic option) performed well, supplying lots of heat with noise levels well below those of the previously installed bleed air heater. Our customers only comment was that at times there was too much heat!” – Universal Helicopters Newfoundland

Mini-Ejector Heater

This advanced-technology system is engineered to provide optimal output at less than cabin ambient noise levels. It consists of a series of miniature heater ejector assemblies strategically located to provide comprehensive heat and defog coverage throughout the aircraft. Simple and elegant, the system delivers warm air where needed without the use of blowers and air distribution ducting.
