While your compressor is off in cold weather, refrigerant can leak into the crankcase and mix with the oil, causing excessive wear on your motor as well as a loss of refrigeration efficiency. When your outside temperature hits 50°F, it automatically turns on, providing a reliable, low cost heat source to help prolong the life of your compressor.
With easy installation for compressors up to 5 horsepower and 40 inches or less around, it includes a flexible lock strap and pre-stripped 18 AWG cold leads for easy connection and hard wiring. The Raychem FreezGard Self Regulating Crankcase Heater is available for use with 120 Volt service - the CCH-1 and for 208 - 277 Volt service - the CCH-2.
For use with refrigerant compressors in non-hazardous areas.
