Aaon P83900 Crankcase Heater Labor-Saving Maintenance: Facilitates a completeThe Aaon P83900 Crankcase Heater is a critical component designed to maintain compressor reliability in commercial HVAC systems. Operating at 480 Volts and delivering 90 Watts of heating power, this belt type heater ensures that refrigerant remains in a gaseous state within the crankcase during off cycles. By preventing refrigerant migration and subsequent oil dilution, the P83900 mitigates the risk of slugging and bearing failure upon startup. This
