Copeland 918-0028-01 Crankcase Heater Refrigerant Can this be used asThe Copeland 918 0028 01 is a high performance immersion type crankcase heater engineered specifically for technical field applications in HVACR refrigeration systems. Operating at 240 Volts with a 65 watt output, this heater maintains optimal oil viscosity within the compressor housing to prevent refrigerant migration during off cycles. By keeping the lubricant at a temperature higher than the coldest part of the system, it mitigates slugging at
