York S1-02550545000 Band Heater 70W 600V 7.3 Inch

Product Description

The YORK S1-02550545000 is a crankcase band heater designed to maintain safe oil viscosity in HVAC compressor crankcases during off cycles and cold ambient conditions. Rated at 70 watts and 600 volts, this band-style heating element wraps around the compressor crankcase and delivers consistent low-level heat to prevent refrigerant migration into the compressor oil. It is sized for a 7.3-inch diameter crankcase. Installation is typically performed by licensed HVAC technicians as part of a compressor protection or system startup procedure.

This crankcase heater is suited for commercial and residential HVAC applications where compressor protection during shutdown periods is required. Band heaters of this type are commonly installed on scroll and reciprocating compressors as part of split systems, rooftop units, or packaged equipment. The 600-volt rating makes this unit appropriate for commercial-voltage equipment where higher supply voltages are present.

Key Features

• 70-watt output provides steady low-level heat to protect compressor oil from refrigerant migration
• 600-volt rated for use in commercial-voltage HVAC equipment
• Band-style design fits around 7.3-inch diameter compressor crankcases
• OEM YORK part for direct replacement in compatible YORK systems
• Crankcase heat reduces risk of compressor slugging on startup

Compatibility

Designed as an OEM-style replacement crankcase band heater for YORK HVAC equipment. Consult YORK documentation or cross-reference the model nameplate to confirm fitment before installation.

Installation Notes

Crankcase heaters are installed by licensed HVAC technicians. De-energize the unit and follow lockout/tagout procedures before removing or replacing the heater element. The heater should be energized for a minimum period before compressor startup as specified by the equipment manufacturer to ensure adequate oil temperature. Verify supply voltage matches the heater rating prior to connection.
