Description
The Carrier 06EA660166 19″ Crankcase Heater 180W 230V is designed to prevent refrigerant migration and maintain oil temperature in compressors within HVAC systems. It is installed around the compressor crankcase in air conditioning and refrigeration units to keep the oil warm when the system is off, reducing damage during startup. By maintaining consistent oil viscosity, the heater ensures proper lubrication of moving components, preventing damage and improving operational stability. Where low ambient temperatures or extended shutdown periods could cause refrigerant condensation in the compressor, supporting stable performance.
