Description
The York S1-02541101000 Crankcase Heater Band supplies controlled heat around a compatible compressor crankcase during shutdown intervals. Its 70W rating provides the specified heating output, while the 480V electrical requirement matches compatible power circuits. The 19.6″-27.1″ circumference range allows the band to fit around the specified compressor housing and maintain close thermal contact in HVAC systems. The heater installs around the compressor with the band secured to the crankcase, and the electrical connection routed to the proper circuit. This heating action keep compressor oil warmer, reducing refrigerant migration into the crankcase and supporting proper lubrication and smoother compressor startup when cooling operation resumes.
