Description
The York S1-02550544000 Crankcase Band Heater is a compressor heating component designed to prevent refrigerant migration and oil dilution during equipment shutdown periods. With a 7.3-inch diameter band configuration, 204-inch lead length, 70-watt output, and 480-volt rating, it is used in HVAC systems to maintain proper compressor crankcase temperature before startup. Wrapped around the compressor housing and secured in position during installation, the heater warms the oil reservoir to reduce liquid refrigerant accumulation inside the compressor. Its controlled heating operation supports smoother startup conditions, reduces internal damage and maintains stable compressor performance in commercial cooling equipment.
