Copeland 918-0001-03 Crankcase Heater

Maintain critical thermal stability in your refrigeration systems with the Copeland 918-0001-03 Crankcase Heater. This immersion type crankcase heater is engineered for high-performance semi-hermetic compressor oil heating, specifically designed to fit Copeland 2D, 3D, and 9 flat or deep sump models. Operating at 120V 65W with a 4.5" insertion length, this component prevents refrigerant migration and oil dilution during the off-cycle. By keeping the lubricant temperature above the system's dew point, it effectively eliminates liquid slugging at start-up and ensures immediate oil pressure development in low-ambient conditions. Its robust construction resists carbonization of the oil while providing a direct heat transfer path. For technicians servicing outdoor or rooftop units, this heater is a fundamental requirement to extend the operational life of Copeland compressors and maintain system efficiency without the complexities of a full pump-down cycle. Trust this OEM-spec heating element for precise fitment and reliable cold-start protection.

• Prevents refrigerant migration to the crankcase during compressor off-cycles, reducing the risk of bearing washouts.
• Optimized 65W power output provides sufficient heat to maintain oil viscosity without risk of oil carbonization or overheating.
• Direct immersion design ensures maximum thermal transfer efficiency compared to external wrap-around heaters.
• Dedicated compatibility for Copeland 2D, 3D, and 9 models ensures a precise seal and secure 4.5" insertion depth.
• Ensures reliable cold-starts by maintaining fluid oil temperature, critical for rooftop and outdoor HVACR installations.

Is this heater compatible with deep sump Copeland models?
Yes, the 918-0001-03 is specifically designed for 2D, 3D, and 9 series compressors with either flat or deep sump configurations.

Does this immersion heater require a specific orientation?
The unit must be fully seated into the crankcase well to ensure the 4.5" heating element is completely submerged in the oil for proper heat dissipation.

Can this be used on 240V systems?
No, this is a 120-volt crankcase heater. Applying 240V will cause immediate component failure and potential damage to the compressor oil reservoir.
