Lennox 72H66 240V CrankCase Heater

The Lennox 72H66 240V Crankcase Heater is a crucial component that improves the dependability and efficiency of HVAC systems, notably air conditioning units and heat pumps. This heater works by warming the compressor's crankcase, preventing the refrigerant from migrating and mixing with the oil in cooler temperatures. By maintaining an ideal temperature within the crankcase, the 72H66 Crankcase Heater guarantees proper lubrication and decreases the danger of compressor damage due to oil dilution. Its installation aids in maintaining the compressor's performance and extending its lifespan, particularly at low ambient temperatures.
