The Air System relies upon a refrigeration subsystem that uses R407c refrigerant to chill 50% Ethylene Glycol / water mixture provided to a cooling coil through which the Blower delivers air to be cooled. The Air System has been designed to maintain 650 SCFM air delivery at a temperature between 35degF and 51degF

The diesel-generator also supplies 208 V, 60 Hz, 3 phase power to a Power Supply which produces 28VDC power for the aircraft systems and 115 V, 60 Hz, 1 phase power to the battery charger and utility outlets. A redundant battery system provides 24VDC to the generator and export power cable.
