Carrier HT32BH943 Crankcase Heater Belt 8-1/2" To 10-1/2" DIA 480V

The Carrier HT32BH943 Crankcase Heater Belt 480V 8-1/2" To 10-1/2" DIA is an electrical heating component designed to maintain compressor crankcase temperature and control refrigerant migration during off cycles. It transfers heat through a resistance element wrapped around the compressor shell, allowing HVAC systems such as split systems, heat pump units, and packaged equipment to maintain suitable compressor conditions. The belt is secured around the outer surface of the crankcase with proper contact for effective heat transfer during operation. It reduce refrigerant accumulation in compressor oil, supports smoother startup conditions, and assists in protecting compressor performance by maintaining the required temperature range within the system.
