Description
The Copeland 918-0002-02 is a 240-volt, 100-watt crankcase heater engineered to protect Copeland compressors from refrigerant migration during off-cycle periods. By maintaining a consistent warmth around the compressor crankcase, this heater prevents liquid refrigerant from accumulating in the oil, which can cause slugging, oil dilution, and premature compressor failure upon startup.
Why Crankcase Heaters Matter
During extended off-cycles — especially in cold ambient conditions — refrigerant can migrate into the compressor crankcase and mix with the lubricating oil. When the compressor restarts, this refrigerant-oil mixture can cause hydraulic slugging and bearing damage. Installing the correct crankcase heater is one of the most cost-effective ways to extend compressor service life and reduce costly callbacks.
