Danfoss 023U4380 Replaceable Core

The Danfoss 023U4380 Replaceable Core is a high-capacity 48-DC solid core filter drier precision-engineered for professional HVACR maintenance and system protection. Utilizing an ELIMINATOR 80% molecular sieve and 20% activated alumina composition, this core provides exceptional moisture and acid removal for systems using high-pressure refrigerants like R410A, R404A, and R134a. Designed for 48 cubic inch shells, it features a 727 cm³ core volume and 612 cm² surface area to ensure maximum adsorption and filtration efficiency without excessive pressure drop. Each Danfoss 023U4380 kit includes a factory-supplied 023U0743 gasket and felt inserts to ensure a leak-proof seal during DCR filter drier shell service. This component is compatible with standard mineral oils, POE, and PAG lubricants, making it a versatile choice for commercial refrigeration and air conditioning system rebuilds.

Key Benefits for Contractors

• Optimized Adsorption: Specifically formulated for high moisture capacity and acid neutralization to prevent compressor burnout and capillary tube plugging.
• Broad Compatibility: Supports a wide range of A1, A2, and A2L refrigerants including R22, R407C, R452A, and R1234ze.
• Oil-Free Ready: Designed to maintain system integrity in modern oil-free applications and systems requiring high cleanliness standards.
• Full Installation Kit: Includes required gaskets to streamline service calls and eliminate the need for separate part sourcing.

Common Questions

Is the 023U4380 compatible with all DCR series shells?
Yes, this 48 cubic inch solid core is designed to fit all standard Danfoss DCR series housing units and comparable competitor shells of the same size specification.

When should I use the 48-DC core versus the 48-DA burnout core?
The 48-DC is the preferred choice for standard moisture and acid removal during regular maintenance or new installations. For systems recovering from a severe motor burnout, the high-acid 48-DA core is typically recommended.

What is the shelf life of the core if the seal is broken?
Filter drier cores are highly hygroscopic. If the foil seal is punctured, the core will begin absorbing ambient moisture immediately; it should be installed immediately or discarded if exposed to the atmosphere for an extended period.
