The ACU-802 Series Air Conditioning/Heating units provide maximum passenger comfort in all types of aircraft. Available in a wide variety of configurations, these units meet the requirements of all aircraft operators regardless of fleet size or local ambient conditions. Using R-134a refrigerant, the ACU-802 Series are environmentally safe causing no damage to the atmospheric ozone.

The units employ an efficient vapor cycle refrigeration system, and for operators requiring heat, can be supplied with an optional reverse-cycle "heat pump" system. The "change-over" from one mode to another is accomplished by a simple toggle switch.
