Carrier HT32CH220 Belt Type Crankcase Heater Overview
The Carrier HT32CH220 is a belt-type crankcase heater engineered to protect compressors from refrigerant migration and liquid slugging during off-cycle periods. Designed to wrap securely around compressor crankcases with a 6 to 7-inch diameter, this heater keeps compressor oil at the proper temperature, ensuring reliable startup and extended compressor life in residential and light commercial HVAC systems.
Key Features
- Belt-type design for secure, uniform contact around the compressor crankcase
- Compatible with 6 to 7-inch compressor body diameters
- 60-inch leads for flexible wiring and easy installation
- Prevents refrigerant migration into compressor oil during off cycles
- Reduces risk of liquid slugging and compressor damage at startup
- Genuine Carrier OEM replacement part
- Designed for long-term, continuous-duty operation
Why Crankcase Heaters Matter
During extended off cycles — especially in cold ambient conditions — refrigerant can migrate into the compressor oil sump, diluting the lubricant and causing damaging liquid slugging when the compressor restarts. The HT32CH220 crankcase heater maintains sump temperature to keep oil viscosity stable, protecting the compressor and maximizing system reliability.
Application
- Residential and light commercial air conditioning and heat pump systems
- Replacement for worn or failed OEM crankcase heaters on compatible Carrier compressors
- Suitable for compressors with 6 to 7-inch diameter crankcases
