Packard CH2803 Crankcase Heater 480V 70 Watts

The Packard CH2803 Crankcase Heater is a 70-watt, 480-volt heating element that warms the compressor and prevents refrigerant migration during off cycles. It operates by converting electrical energy into controlled heat output through a resistance element, raising oil temperature to reduce evaporative dilution and foaming. Implemented in scroll and reciprocating economizers, condensing units, and HVAC systems used in refrigeration and air conditioning equipment, it protects motor lubrication quality, reduces start-up strain, and limits liquid vapor accumulation inside the combustion chamber during idle periods, ensuring proper oiling integrity and smoother condenser involvement at system restart.
