Description
Copeland 018-0091-27 Crankcase Heater Overview
The Copeland 018-0091-27 is a 120-volt, 137-watt crankcase heater engineered to protect refrigeration and air conditioning compressors from refrigerant migration during off-cycle periods. By maintaining the compressor crankcase at an elevated temperature, this heater prevents liquid refrigerant from mixing with the compressor oil — a leading cause of compressor damage and premature failure.
Key Features
- OEM Copeland replacement crankcase heater for reliable, brand-matched performance
- Operating voltage: 120V
- Wattage: 137W
- Prevents refrigerant migration into compressor oil during off cycles
- Helps extend compressor service life and reduce costly failures
- Designed for straightforward installation on compatible Copeland compressor models
Why Use a Crankcase Heater?
During compressor shutdown, refrigerant can migrate into the crankcase and dilute the lubricating oil. When the compressor restarts, this refrigerant-oil mixture can cause slugging, bearing wear, and catastrophic compressor failure. A properly functioning crankcase heater keeps the oil warm and refrigerant-free, ensuring reliable startups and maximizing compressor longevity.
Application
- Compatible with select Copeland compressor models — verify fitment using OEM documentation or your Copeland parts reference
- Suitable for commercial refrigeration and air conditioning systems
- Ideal for replacement in systems operating in low-ambient or cold-climate environments
