Copeland 918-0009-00 Crankcase Heater

For service technicians maintaining Copeland Copelametic and Discus compressors, the Copeland 918-0009-00 is a critical OEM replacement part designed to prevent refrigerant migration during off-cycles. This bolt-on crankcase heater provides a consistent 65 watts of heat at 120 volts, ensuring the oil remains at a high enough temperature to prevent liquid slugging at startup. Engineered for the Copeland 3A, 3R, E, L, M, and N series, this heater is an essential safeguard for systems exposed to low ambient conditions where refrigerant tends to migrate to the coldest point in the circuit—the compressor crankcase.

The rugged construction of this 65W heater ensures thermal stability without carbonizing the refrigeration oil. Its bolt-on design allows for direct attachment to the compressor housing, providing efficient heat transfer compared to wrap-around alternatives. By maintaining the crankcase temperature above the ambient dew point, this crankcase heater kit eliminates the risk of oil dilution, protecting the mechanical integrity of the bearings and ensuring immediate oil pressure upon system demand. This part is a drop-in solution for contractors looking to restore factory-spec protection to high-side refrigeration assets.

• Optimized Compatibility: Specifically designed for Copeland 3A, 3R, E, L, M, and N series compressors (excluding deep sump models).
• Prevents Liquid Slugging: Maintains oil temperature to prevent refrigerant from condensing in the crankcase during the off-cycle.
• Efficient Heat Transfer: The bolt-on type mounting provides superior thermal contact with the compressor body for consistent 120-volt operation.
• Reliable Lubrication: Keeps oil viscosity within operating range, ensuring immediate lubrication of internal components at startup.
• Saves Compressor Life: Reduces wear on internal assemblies by neutralizing the effects of cold-weather refrigerant migration.

Which compressor models are compatible with the 918-0009-00?
This heater is designed for Copeland Semi-Hermetic units, specifically the 3A, 3R, E, L, M, and N series. It is not intended for use with deep sump compressor models.

Why is a 120V crankcase heater necessary for refrigeration systems?
In low ambient environments, refrigerant naturally migrates to the compressor during the off-cycle. Without a crankcase heater, the liquid refrigerant mixes with the oil, leading to foaming and mechanical failure at startup.

Is this an OEM Copeland part?
Yes, the 918-0009-00 is an authentic Copeland OEM heater kit, ensuring exact physical fit and electrical compliance for specified compressor series.
