Daikin-McQuay 074513301 Crankcase Heater 319848-301 using a low-voltage 24VAC signalThe Daikin McQuay 074513301 Crankcase Heater is a critical component for maintaining compressor integrity in commercial and industrial HVACR systems. Operating at 120V and delivering a steady 70 Watts of thermal output, this crankcase heater is engineered to keep the compressor oil temperature above the refrigerant saturation point during the off cycle. This thermal regulation is essential to prevent refrigerant migration, which can lead to oil
