025-34523-000 York Compressor Oil Heater For Screw Compressor DXS / MTS / CTS – HVAC Replacement Part

25-34523-000 is a York (YORK) electric heater (Electrical Heater), produced by Johnson Controls, used for heating the oil tank and lubrication system of York chillers. It is also commonly referred to as an oil heater. During the shutdown of the unit, refrigerant is prone to migrate and dissolve into the lubricating oil, resulting in dilution of the oil and a decline in lubrication performance. This can cause liquid impact in the compressor and component wear upon restart. This heater continuously heats the oil tank, maintaining the oil temperature above the system's minimum temperature, preventing refrigerant from dissolving into the oil, and ensuring the strength of the oil film and lubrication performance. It is a key protective component for the safe startup of the compressor. This product is manufactured according to the original factory specifications, with installation dimensions consistent with the original equipment, and can be directly replaced.
