Daikin-McQuay 070902801 Crankcase Heater 90W 120V

The Daikin-McQuay 070902801 Crankcase Heater is an electrical appliance that is used to regulate the temperature of the crankcase of a compressor in HVAC systems particularly in heat pumps and air conditioners. This crankcase heater operates at a 120V power output of 90 watts when the compressor is off to provide heat to warm the crankcase to ensure that during cold times, refrigerant does not seep into the oil and dilute it. Maintaining the crankcase warm provides the much-needed vaporization of the refrigerant which turn makes the system efficient and reliable. Some of the advantages of using this crankcase heater include easier start-up of the compressor, less mechanical damage, and longer service life of the HVAC equipment.
