Description
The Danfoss 7773107 is a C-Heater Belt crankcase heater designed to protect refrigeration and HVAC compressors from refrigerant migration and liquid slugging during off-cycle periods. By maintaining the compressor crankcase at an elevated temperature, this belt-style heater prevents refrigerant from accumulating in the compressor oil, safeguarding the compressor against damaging startup conditions and extending overall system life.
Key Features
- Belt-style crankcase heater for secure, wraparound contact with the compressor body
