Copeland 918-0056-21 Heater 321702-401 ensuring reliable HVAC pressure sensingFor industrial refrigeration and commercial HVAC systems, the Copeland 918 0056 21 480V crankcase heater is a mission critical component designed for robust compressor protection. Operating at 480 Volts, this crankcase heater ensures that the oil reservoir remains above the refrigerant saturation point during off cycles. This thermal regulation is essential to prevent refrigerant migration, which can lead to hazardous oil dilution and liquid slugging
