Packard CH2303 Crankcase Heater 70W 480V

The Packard CH2303 Crankcase Heater 70W 480V is a electrical component that is used to power a refrigeration compressor when the system is not running. It inhibits the movement of refrigerant and condensation within the oil, which may cause less lubrication and hard starts in the HVAC systems. This heater is fitted on the compressor body to maintain a constant temperature to ensure that the viscosity of oil does not change. It is also in the start-up of the compressor and in the protection of the conditions within the refrigeration system.
