Danfoss 120Z0459 PTC Crankcase Heater 27W 230-600V

The Danfoss 120Z0459 PTC Crankcase Heater is a specific device used in HVAC equipment, especially air conditioners and refrigeration units. It is run at a voltage range of 230 to 600 volts with a power of 27 watts. The crankcase heater not only provides the prevention against refrigerant migration but also the lubrication of the compressor's crankcase to the adequate range. This improves the life and effectiveness of the HVAC system. It prevents cold start problems by minimizing damages. Moreover, it prevents excessive viscosity of oil, hence allowing efficient running at colder temperatures by keeping the crankcase warm.
