Packard CH101340 Crankcase Heater 54W 480V

The Packard CH101340 Crankcase Heater 54W is an electric heating component used in commercial equipment to maintain proper compressor temperature during shutdown periods and low ambient conditions. It wraps around the compressor crankcase to keep refrigerant from mixing with compressor oil, which assists in stable startup operation and oil circulation. This heater is commonly placed in commercial air conditioning units, refrigeration equipment, rooftop systems, and heat pump applications operating with 480V electrical configurations. Within the HVAC system, it works as a protective component that assists compressor performance, temperature control, and operational consistency during routine system cycles.
