York S1-025-49273-000 Heater 320074-702 Superior Safe Start: Integrated 15-secondThe York S1 025 49273 000 Crankcase Heater is a heavy duty compressor band heater engineered specifically for high voltage industrial HVAC systems. Operating at 460V and delivering a steady 40W output, this 50 inch heater band is essential for maintaining optimal oil viscosity in large frame compressors during the off cycle. By keeping the crankcase temperature above the refrigerant saturation point, it effectively eliminates refrigerant migration and
