Danfoss 023U4381 Solid Core

The Danfoss 023U4381 is a high-performance 48-DC filter drier core engineered for professionals managing commercial refrigeration and air conditioning systems. This assembly features a robust solid core composed of 80% molecular sieve and 20% activated alumina, providing a dual-action solution for both moisture absorption and acid neutralization. Designed for use in DCR filter drier housings, the 48-DC is fully compatible with a wide range of refrigerants, including R410A, R134a, R404A, and R507, as well as HCFC options like R22. Its optimized grain size ensures maximum dirt retention while maintaining a low pressure drop across the liquid or suction line. Built to withstand pressure surges and vibration, this core is an essential component for protecting compressors from contaminants and ensuring system longevity. Each unit includes the necessary gaskets to ensure a gas-tight seal during replacement in standard 4-3/4 inch shells.

• Dual-Action Filtration: Combines high drying capacity with effective acid adsorption to neutralize corrosive byproducts in the system.
• Universal Compatibility: Optimized for use with POE and PVE lubricants and compatible with most HFC and HCFC refrigerants.
• Structural Integrity: The solid core design prevents disintegrating or "dusting," protecting expansion valves and sensitive orifices.
• Efficient Debris Removal: Engineered uniform grain size provides consistent filtration of solid particles without restricting flow.
• Complete Install Kit: Includes the 023U0743 gasket and felt gaskets to facilitate a complete leak-free service.

What is the primary difference between the 48-DC and 48-DM cores?
The 48-DC contains 20% activated alumina for acid removal, making it ideal for systems where burnout has occurred or acid buildup is a concern. The 48-DM is 100% molecular sieve, focused strictly on high-moisture adsorption.

Is the Danfoss 023U4381 suitable for suction line applications?
Yes, the 48-DC solid core is designed for both liquid and suction line duty, providing essential protection for the compressor following a system failure or maintenance opening.

Can these cores be used in CO2 (R744) systems?
This core is compatible with R744 (CO2) applications, provided they are within the high-pressure operating limits of the DCR housing being utilized.
