Description
The Carrier HT32TC943 Crankcase Heater warms the compressor sump to prevent refrigerant migration and oil dilution during off cycles. It is used in HVAC systems within compressor assemblies of air conditioning and refrigeration units, where temperature drops can cause coolant to condense in the motor case. The heater operates by maintaining localized heat around the motor’s body, keeping oil viscosity stable and reducing liquid slugging during startup. It is applied in cooling equipment to maintain turbocharger readiness, protecting internal components from cold-start stress and improving operational stability in sealed refrigeration circuits.
