Trane HTR15171 Crankcase Heater 322055-301 A DPDT relay provides aThe Trane HTR15171 Crankcase Heater is a heavy duty 240 volt belly band heater engineered to mitigate refrigerant migration and preserve compressor lubrication during the off cycle. Designed for 6. 5 inch diameter compressors, this 70 watt heating element maintains oil temperature above the ambient dew point, preventing the dilution of refrigeration oil and reducing the risk of catastrophic liquid slugging upon startup. Featuring 62 inch lead wires,
