Copeland Crankcase Heaters

Copeland’s complete line of crankcase heaters offers critical compressor protection. They keep the crankcase warm while the compressor is in an off cycle; an important step in minimizing refrigerant migration to the compressor. And, we’ve designed our crankcase heaters with limited wattage to help avoid overheating and carbonizing of the oil.

Anytime a compressor is not operating, refrigerant vapor moves to the crankcase. And anytime the compressor becomes colder than the evaporator, that migration is accelerated. The result: liquid slugging at start-up that can ruin a compressor. While pump-down cycles help protect against refrigerant migration, often system operating requirements, cost or customer preference make the use of pump-downs impractical. The solution: a crankcase heater from Copeland.

Also, oil in outdoor and rooftop units exposed to cold winter winds can become so viscous that the compressor cannot develop oil pressure. That’s why Copeland recommends the use of crankcase heaters on all refrigeration systems in which the compressor is exposed to cold ambient temperatures – to keep the oil warm enough to remain fluid.
