Copeland 918-0518-02 Insertion Type Crankcase Heater
The Copeland 918-0518-02 is an insertion-type crankcase heater engineered to protect refrigeration and air conditioning compressors from the damaging effects of refrigerant migration. By maintaining the crankcase oil at an elevated temperature during off cycles, this heater prevents liquid refrigerant from mixing with the compressor oil — a leading cause of compressor failure and premature wear.

Why Use a Crankcase Heater?
During shutdown periods, refrigerant can migrate to the compressor crankcase and mix with the lubricating oil. On startup, this refrigerant-oil mixture can cause foaming, oil loss, and mechanical damage. A properly functioning crankcase heater keeps the oil warm enough to drive off refrigerant, ensuring the compressor starts with clean, uncontaminated oil every time.
