Apr 2, 2018 · CRANKCASE HEATERS. The crankcase heater is designed to help combat refrigerant migration. The function of the crankcase heater is to hold the oil in the compressor’s crankcase at a temperature higher than the coldest part of the system. This will cause the crankcase to have a slightly higher pressure than the rest of the system.
Oct 28, 2022 · Why are crankcase heaters necessary? Systems with crankcase heaters have them for a reason, and while the outdoor ambient temperature is one factor, it isn't the REASON why crankcase heaters exist. Refrigerant is attracted to the oil in the compressor when the system goes into the off cycle.

Crankcase heaters or compressor refrigerant heaters can be found on all kinds of HVAC compressors. Especially HVAC compressors that are expected to be in service under low ambient conditions. Like heat pumps and even some air conditioners. I’ll take the questions about Crankcase Heaters and Compressors and answer them separately.
Feb 7, 2024 · The Purpose of Crankcase Heaters. Crankcase heaters are critical in HVAC systems: they prevent refrigerant migration and accumulation in the compressor when the system is off. This migration can lead to refrigerant mixing with the oil, lowering its lubrication ability and potentially causing compressor damage during startup.
EasyHeat™ crankcase heaters provide a simple, effective and reliable solution for heating motors and compressors. They are designed for use as a heater on air conditioning and refrigeration metal compressors up to 42 in (1 m) in circumference.
