Copeland 918-0518-01 200W Crankcase Heater 5-1/2" DIA 40" Leads 240 VAC

The Copeland 918-0518-01 Crankcase Heater is crucial because it prevents refrigerant migration while ensuring that the performance of compressors remains optimum. It 240 VAC and has a power rating of 200 watts, intended to maintain constant temperature during off cycles for crankcases containing compressors. By providing heat on control, it works in heating up a compressor crankcase. This prevents condensing refrigerant from getting inside the unit which may cause damage and inefficiency. It also helps to avoid liquid slugging, hence keeping refrigerant as vapor that would harm internals of compressor and reduce functionality.
