Copeland 918-0028-01 Crankcase Heater

The Copeland 918-0028-01 is a high-performance immersion type crankcase heater engineered specifically for technical field applications in HVACR refrigeration systems. Operating at 240 Volts with a 65-watt output, this heater maintains optimal oil viscosity within the compressor housing to prevent refrigerant migration during off-cycles. By keeping the lubricant at a temperature higher than the coldest part of the system, it mitigates slugging at startup and ensures immediate lubrication of critical internal components. This crankcase heater replacement is essential for extending the operational lifecycle of compatible Copeland compressors, particularly in low-ambient environments where cold starts can lead to mechanical failure. The immersion-style design provides superior thermal transfer compared to wrap-around styles, delivering direct heat to the oil reservoir. Professionals should verify the mounting port size and electrical load requirements to ensure a seamless compressor maintenance integration and peak system reliability.

• Direct Heat Transfer: Immersion design ensures energy-efficient thermal distribution directly into the lubricant.
• Cold Start Mitigation: Prevents liquid refrigerant from mixing with oil, reducing the risk of bearing washouts.
• Precision Electrical Specs: 240V/65W configuration matches standard industrial and commercial power profiles.
• Rugged Build Quality: Constructed to withstand the continuous thermal cycling typical of intensive HVACR duty.

Common Questions

How do I confirm if this immersion heater fits my specific Copeland model?
Verify the compressor’s housing for a dedicated heater well. This unit is designed for models with a specific immersion port; cross-reference your compressor's parts list with the 918-0028-01 part number.

Does this heater require a separate thermostat for operation?
While some technicians wire heaters to run continuously during the off-cycle via the contactor's auxiliary contacts, integrating a dedicated ambient thermostat can improve energy efficiency by only activating the heater when temperatures drop below a specific set point.

Can I use a 240V heater on a 208V circuit?
Using this 240V heater on a 208V circuit will result in a significant drop in wattage output, which may fail to keep the oil sufficiently warm in extreme cold. Always match the voltage to the system specifications for full performance.
