Description
Copeland 918-0518-01 Insertion Type Crankcase Heater
The Copeland 918-0518-01 is an insertion-style crankcase heater engineered to protect refrigeration and air conditioning compressors from refrigerant migration during off-cycle periods. By maintaining the crankcase oil at an elevated temperature, this heater prevents refrigerant from dissolving into the compressor oil — a leading cause of bearing wear, slugging, and premature compressor failure. It is a direct OEM Copeland replacement, ensuring a reliable, drop-in fit for compatible scroll, reciprocating, and semi-hermetic compressor models.

Application
This crankcase heater is designed for use with compatible Copeland compressors in commercial and residential HVAC/R systems. It is especially important in low-ambient or seasonal installations where compressors may sit idle for extended periods, allowing refrigerant to migrate into the crankcase oil. Always verify compatibility with the specific compressor model before installation.
