Description
The York S1-02538925000 Crankcase Heater Band supplies controlled heat around a compatible compressor crankcase to reduce refrigerant migration into the compressor oil during shutdown. Its 70W rating provides the specified heating output, while the 480V requirement corresponds to compatible electrical circuits. The 21.8″-29.0″ circumference range allows the band to fit around compatible compressor crankcases and maintain thermal contact with the housing. The heater installs around the compressor in HVAC systems with the electrical leads connected to the proper circuit. Its heating action maintains warmer crankcase conditions, supporting proper oil condition, controlled compressor startup, and stable refrigeration operation after extended shutdown times.
