Mars 32419 Crankcase Heater for Copeland Compressors

Product Description

The MARS 32419 is a crankcase heater designed for use with Copeland compressors in residential and commercial HVAC and refrigeration systems. Crankcase heaters are a critical component in any system that uses a reciprocating or scroll compressor. They keep the compressor oil warm during off cycles, which prevents refrigerant from migrating into the crankcase and mixing with the lubricating oil. When refrigerant dilutes compressor oil, the result is poor lubrication, increased wear, and in some cases compressor failure on startup. Installing a crankcase heater like the MARS 32419 is a standard preventive measure that extends compressor life and reduces costly service calls. HVAC technicians rely on crankcase heaters in systems that are located in cold climates or that experience long off periods. The heater wraps around or mounts to the lower portion of the compressor body, applying low-level heat to the oil sump area at all times when the compressor is off. This ensures that when the compressor starts, the oil is free of refrigerant and ready to lubricate moving parts immediately. The MARS 32419 is manufactured by Motors and Armatures, Inc., a well-known supplier of replacement HVAC components. It is engineered as a direct replacement for crankcase heaters used on Copeland compressor models, making it a go-to option for field technicians completing compressor maintenance, repair, or replacement work. Whether you are servicing a rooftop unit, a condensing unit, or a refrigeration rack, this heater is a reliable replacement part to keep on the service truck.
