Air conditioning and heating units

The ACU-2000 Series trailer-mounted Aircraft Heating Unit offers a range of models that deliver from 500,000 up to 750,000 Btu/Hr of clean pressurized, heated air to all aircraft or facilities equipped with a standard 8-inch (203mm) connector. The unit provides filtered air to maintain passenger comfort during aircraft turnover or to maintain cabin temperature during layovers to prevent damage to onboard plumbing systems. The gasoline engine supplies the thermal and mechanical energy required to operate the heating system. In the 500 KBtu/Hr model, the inlet air is heated by the blower heat of compression and then passes through a heat exchanger that recovers energy from the engine coolant circuit. In the 750 KBtu/Hr models an additional heat exchanger recovers energy from the engine exhaust. The recovery and use of engine waste heat make the ACU-2000 a very energy-efficient unit. The design is inherently safe thru its avoidance of an open flame and its use of the exhaust gas to water heat exchanger which ensures no combustion by-products are introduced into the delivered air stream and eliminates the possibility of an over-temperature condition in the aircraft ductwork.

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 is environmentally safe causing no damage to the atmospheric ozone. Folosind agent frigorific R-134a, seria ACU-802 este sigură pentru mediu și nu provoacă daune ozonului din atmosfera. 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.

The CF40 is a mobile electric air conditioning unit designed to cool or, when equipped, heat an aircraft to obtain the adequate temperature in the cockpit and cabin during pre-flight operations, boarding, and maintenance. It has sufficient cooling power for narrow and wide-body aircraft (C to E types) and meets the needs and requirements of civil aircraft in all climates. It can be specifically configured for continental, tropical, or desert conditions. The CF40 is built with top-of-the-line material, resulting in extremely low maintenance requirements during its lifetime. The cooling circuit does not need to be opened and maintained before 100,000 hours of operation. The CF40 utilizes the R134a refrigerant which has zero ozone depletion potential.
