Copeland 918-0002-01 Crankcase Heater

Professionals in the field know that a cold start is the fastest way to kill a compressor. The Copeland 918-0002-01 Crankcase Heater is a critical immersion-type heating element specifically engineered for high-voltage industrial applications. Operating at 480 Volts with a 100-Watt power output, this heater maintains the refinery or refrigeration oil at a temperature high enough to prevent refrigerant migration during the off-cycle. By keeping the oil warmer than the rest of the system, it ensures that refrigerant does not condense in the crankcase, preventing flooded starts and the catastrophic bearing washout that follows.

This OEM Copeland heater is designed for direct insertion into the compressor well, providing more efficient thermal transfer than standard wrap-around belly bands. It is optimized for use with Copeland Discus and Coplalame compressors where precise oil temperature control is a requirement. Integrating this immersion crankcase heater into your preventative maintenance routine is the most reliable way to prevent liquid slugging and extend the operational life of heavy-duty HVACR equipment. For technicians servicing 460-480V systems, this crankcase heater replacement is a standard-spec component for maintaining compressor reliability in low-ambient conditions.

• Direct Thermal Transfer: The immersion style design heats the oil directly from within the well for superior efficiency over external bands.
• Voltage Compatibility: Specifically rated for 480V systems, ensuring correct amperage draw and consistent 100W heat delivery without overloading circuits.
• Eliminates Dilution: Prevents refrigerant from mixing with the lubricant, maintaining oil viscosity and protecting internal bearings.
• Rugged Construction: Built to withstand constant thermal cycling and exposure to compressor oils without degradation.

How do I check if the immersion heater is functioning?
Disconnect power and use a multimeter to check for resistance across the leads. An open circuit (OL) indicates a failed internal element that requires immediate replacement.

Does this heater run while the compressor is operating?
No. For proper crankcase heater wiring, it must be energized only during the off-cycle, typically through the auxiliary contacts on the compressor contactor.

Can this be used on any compressor?
This is an immersion type heater. It is only compatible with compressors equipped with a dedicated heater well and must match the 480V/100W specification for safe operation.
