York S1-025-41100-000 Crankcase Heater

As a service tech, you know that keeping the compressor oil at the correct temperature during the off-cycle is critical for system longevity. The York S1-025-41100-000 Crankcase Heater is a rugged belt type crankcase heater designed to prevent refrigerant migration and oil foaming. Operating at 240 volts with a 70-watt output, this heater provides consistent thermal energy to ensure the HVAC compressor remains protected in cold ambient conditions. This specific compressor heater band features a flexible diameter range of 19.6-27.1", allowing it to wrap securely around a variety of large commercial and residential scroll compressors. With 16-inch leads for straightforward field wiring, it serves as a reliable OEM replacement part for York and Johnson Controls units. By maintaining the crankcase temperature above the system's dew point, this 240V 70W heater eliminates the risk of liquid slugging, protecting internal bearings from premature wear during startup.

• Prevents Refrigerant Migration: Stops refrigerant from condensing into the oil during the off-cycle, preventing lubrication failure.
• Adjustable Tension: The belt-style design accommodates diameters from 19.6" to 27.1", ensuring a tight fit for optimal heat transfer.
• Rugged Lead Construction: Includes 16" high-temperature leads suitable for standard control box terminations.
• Specific Voltage Compatibility: Rated for 240V AC operation, matching standard commercial voltage requirements.

Is this heater compatible with multi-stage scroll compressors?
Yes, as long as the compressor belly diameter falls within the 19.6" to 27.1" range and the supply voltage is 240V.

How tight should the heater band be installed?
The band should be snug against the bottom of the compressor shell to ensure maximum conduction without over-stretching the tensioning spring.

Can I use this on a 208V circuit?
While it will function, the wattage output will be reduced below the 70W rating, which may decrease its effectiveness in extreme cold.
