Description
The York S1-02550545000 Crankcase Heater Band delivers 70W of heat and fits compressors with a 7.3-inch diameter, operating on 400V power to keep the compressor crankcase at the proper temperature during shutdown periods. It wraps around the compressor housing, providing continuous warmth that limits refrigerant migration into the compressor oil before startup. Installed around compatible compressors in HVAC systems, it forms part of the compressor protection assembly during idle and startup cycles. Controlled heating supports proper compressor operation, promotes stable startup performance, and maintains consistent system operation.
