York S1-025-37421-460 Crankcase Heater 318172-701 How do I interpret theThe York S1 025 37421 460 is a high specification belt type crankcase heater engineered for heavy duty industrial and commercial HVAC applications. Operating at 480 Volts with a 70 Watts power rating, this component is essential for maintaining optimal compressor oil temperature. By keeping the lubricant warmer than the coldest part of the system, it effectively prevents refrigerant migration and subsequent liquid slugging during low ambient startups.
