Lennox 72H66 240V CrankCase Heater

The Lennox 72H66 240V Crankcase Heater is a part that upgrades the stability and effectiveness of HVAC systems. This heater is used to warm the crankcase of the compressor to prevent the refrigerant from moving and diluting the oil when cold. It ensures that the temperature within the crankcase is perfect to ensure adequate lubrication while also reducing the risk of compressor damage caused by oil dilution. Its installation helps in keeping the compressor in working condition and also increases the service life of the compressor especially when used in low ambient temperatures.
