Aircraft Air Conditioning Systems
Our all-electric HVAC systems provide total climate control for aircraft, featuring Motor-Compressor-Condenser assemblies that deliver 15,00036,000 BTU/hr cooling. These systems use HFC-134a refrigerant for environmental compliance and can retrofit older R-12 units. The modular design allows installation in diverse aircraft, from single-seat crop dusters to 50-passenger airliners, ensuring optimal cabin comfort and equipment reliability.
Motor-Compressor Assemblies
Our motor-compressor assemblies offer robust refrigerant pumping for split air conditioning systems. Models like the Z99-800 Series feature cog drive belts for consistent performance under extreme conditions. These units integrate with condenser modules to form efficient MCC systems, suitable for turbine-powered aircraft worldwide. They are FAA-PMA certified and compatible with R-134a refrigerant standards.
Evaporator-Heater Systems
Evaporator-heater combinations provide dual cooling and heating capabilities in a single installation. Units like the SZ63H002 series deliver 300700 SCFM airflow for rapid cabin temperature control. They are designed for seamless integration with existing aircraft electrical systems and include heat strips for supplemental warmth, making them ideal for varying operational environments.
STC Upgrades
We provide FAA-approved STC upgrades for legacy aircraft, including the Falcon 10 R-134a conversion kit. These modifications replace outdated compressors and pulleys with modern, efficient components while maintaining structural integrity. Our STC portfolio covers models like the Twin Otter, Citation 500, and DC-3 Basler conversions, ensuring compliance with current aviation standards.
