Carrier HT32CH245 Crankcase Heater

The Carrier HT32CH245 Crankcase Heater is an electrical component used to warm compressor oil when the system is off. It is mounted around or inside the compressor housing, where it maintains oil temperature above refrigerant saturation levels in HVAC systems. It prevent refrigerant migration into the compressor during idle, reducing the amount of oil dilution and liquid slugging during startup. This supports compressor starting, improved lubrication at startup, and reduced mechanical load on internal components. It is commonly used in outdoor condensing units, operating in variable ambient conditions to improve and extend compressor operating stability.
