NASI – NTEC ELECTRIC SUPPLEMENTAL AIR CONDITIONING SYSTEM

Aircraft with limited or no access to passenger gate cooling systems use NTEC Electric Vapor Cycle Air Conditioning units operating on any available power, aircraft 400Hz GPU (Ground Power Units) or 50Hz/ 60Hz standard utility power.

NTEC Systems are also available in 28 VDC for helicopters, private and corporate aircraft.

SUPPLEMENTAL HEAT CONFIGURATION

HEATING CAPACITY: 15,300 Watts Rated (52.200 Btu)

Supplumental Heat is supplied by thermal heater rods inserted with the evaporators. When selecting supplemental heat, power is supplied through circuit breakers to separate heater relays.

Supplemental heat control is equipped with thermal safety switches, preventing heating operations when the evaporator coil is too hot or when ambient air temperature is above a pre-determined setting.

Supplemental heating systems are also equipped with evaporator/heater fan airflow safety switches preventing the heater relay from energizing without adequate system airflow.
