Overview
The Copeland 918-0031-05 crankcase heater round insert is engineered to protect semi-hermetic and hermetic compressors in refrigeration and air conditioning systems. Copeland recommends the use of crankcase heaters on all refrigeration systems in which the compressor is exposed to cold ambient temperatures to keep the oil warm enough to remain fluid. The round insert design provides efficient heat distribution and reliable thermal protection.
Key Features
- Easy drop-in installation with rugged construction for longer life
- Limited wattage design helps avoid overheating and carbonizing of the oil
- UL-Recognized and fully tested to meet all specifications
- Minimizes refrigerant migration to the compressor and prevents liquid slugging during startup
- Round insert form factor for flexible mounting options
- Suitable for commercial and industrial refrigeration applications
Technical Specifications
Verify specific voltage and wattage ratings with manufacturer documentation or your system integrator before ordering, as the 918-0031-05 may be available in multiple electrical configurations to match your compressor requirements.
Typical Applications
- Commercial refrigeration systems exposed to cold ambient temperatures
- Rooftop air conditioning units in winter conditions
