Danfoss 120Z0459 Crankcase Heater A compromised diaphragm leads toThe Danfoss 120Z0459 Crankcase Heater is a critical PTC crankcase heater designed to prevent refrigerant migration and ensure reliable compressor lubrication during off cycles. Since this is a positive temperature coefficient (PTC) component, it provides self regulating heat output, drawing 27 Watts to maintain the oil sumps temperature without requiring external thermostats. This model is a direct cross reference for the Danfoss 7303507, making it a
