Description
The Rheem-Ruud 44-17402-47 Belly Band Crankcase Heater 70W 230V is a heating element used to cover around a compressor in HVAC systems. It provides controlled heat to the compressor shell when the system is off, preventing refrigerant migration into the oil and reducing the oil dilution. It is installed on the outdoor condensing unit as part of compressor protection. It helps ensure proper oiling at startup and supports reliable compressor operation under varying ambient conditions of the unit in the system.
