Description
The Trane HTR10244 Crankcase Heater 40W 575V 32W AT 46 is an electric heating element used to prevent refrigerant migration and oil dilution within compressor units. It operates by maintaining a controlled temperature around the compressor sump, reducing condensation and keeping oil viscosity stable during off cycles. It is mounted externally on the compressor housing and connected to the power supply for continuous or controlled operation. Used in HVAC systems such as air conditioning and refrigeration units, it protects compressor components, supports reliable startup, and contributes to consistent system efficiency.
