Copeland 918-0028-00 Heater

The Copeland 918-0028-00 is a high-performance 120V 100W insertion well heater designed for direct integration into compressor sumps. Engineered specifically for Copeland Discus compressors and Copeland Scroll models, this crankcase heater prevents refrigerant migration and maintains oil temperature above the saturation point during off-cycles. This ensures reliable cold weather compressor startup by reducing oil dilution and preventing liquid slugging, which are common causes of premature mechanical failure in commercial refrigeration and HVAC systems. The insertion-style design provides superior thermal transfer compared to wrap-around heaters, focusing heat directly on the oil reservoir. Technicians should verify the well depth and crankcase heater voltage compatibility before installation. This 100-watt component is built for heavy-duty thermal cycling in demanding applications, ensuring consistent viscosity for internal lubrication during the initial stage of the lubrication cycle.

Key Benefits

• Superior heat transfer efficiency via insertion well heater design for direct oil warming.
• Optimized for Copeland compressor parts archives, ensuring precise fitment in OEM wells.
• Minimizes refrigerant dilution to protect mechanical bearings during high-torque startups.
• Standard 120V configuration facilitates easy integration with existing control circuits.
• Durable construction resists thermal fatigue in high-cycle commercial environments.

Common Questions

What is the primary function of the Copeland 918-0028-00?
This heater maintains the compressor oil temperature to prevent refrigerant from condensing in the crankcase during the off-cycle, which prevents oil foaming and lubrication failure at startup.

Can this heater be used in a scroll compressor?
Yes, provided the compressor is equipped with the appropriate internal insertion well. It is frequently used in both Copeland Scroll and Discus semi-hermetic models.

How do I verify if this 100W heater is compatible with my system?
Check your compressor's nameplate and parts manual to ensure the voltage matches the 120V specification and the well dimensions accommodate a standard immersion heater core.
