Description
Rheem-Ruud 44-17402-47 Belly Band Crankcase Heater Overview
The Rheem-Ruud 44-17402-47 is a belly band style crankcase (CC) heater designed to protect compressors from refrigerant migration during off cycles. By maintaining a consistent heat level around the compressor crankcase, this heater helps prevent liquid refrigerant from accumulating in the compressor oil, reducing the risk of slugging, oil dilution, and premature compressor failure — especially during cold-weather startups.
