Description
The Copeland 918-0028-00 is a 120-volt, 100-watt insertion well heater designed to maintain proper oil temperature in compressor crankcases and sump assemblies. By keeping the oil warm during off-cycle periods, this heater helps prevent refrigerant migration into the compressor oil — a leading cause of compressor damage and premature failure.
Key Features
- 120V operating voltage for compatibility with standard single-phase power supplies
- 100W heating output for effective oil temperature maintenance
- Insertion well design for secure, direct installation into the compressor housing
- Genuine Copeland OEM replacement part (SKU: 918-0028-00)
- Helps prevent refrigerant migration and oil dilution during compressor off cycles
- Supports longer compressor service life and improved system reliability
Application
This insertion well heater is engineered for use with compatible Copeland compressors in commercial and residential refrigeration and air conditioning systems. It is particularly important in applications where the compressor is subject to extended off cycles or low ambient temperatures, conditions that increase the risk of liquid refrigerant accumulating in the crankcase.
Why Use a Crankcase / Insertion Well Heater?
Refrigerant migration into compressor oil reduces lubrication effectiveness and can cause compressor slugging at startup. Installing and maintaining a properly functioning insertion well heater is a best practice recommended by Copeland to protect compressor warranties and maximize equipment uptime.
