Danfoss 023Z4827 Filter Drier

The Danfoss 023Z4827 Filter Drier (Model DML 053S) is a professional-grade hermetic liquid line filter drier engineered for high-pressure refrigeration and air conditioning systems. This unit features a 100% molecular sieve solid core (3Å), specifically optimized for HFC refrigerants such as R410A, R134a, and R404A, as well as being compatible with HCFCs like R22. Its design focuses on maximum moisture adsorption to prevent acid formation and hydrolysis, protecting the compressor and ensuring the systemic integrity of commercial refrigeration units, chillers, and air handling equipment.

Constructed with a one-piece plasma welded steel shell and 10mm ODF solder connections (copper-plated steel), the Danfoss DML 053S provides a robust Maximum Working Pressure (MWP) of 46 bar (667 psig). The internal felt pad effectively prevents core breakdown due to system vibration, while the 25 µm filter ensures high dirt retention with minimal pressure drop. This liquid line drier is essential for veterans performing preventive maintenance or system repairs where moisture and contaminant control are non-negotiable for long-term performance.

Key Benefits:

• High Moisture Capacity: The 100% molecular sieve core provides superior water adsorption, critical for systems using POE and PAG oils where acid formation is a risk.
• Contaminant Filtration: Integrated 25-micron filter traps solid particles to protect sensitive expansion valves and compressor internals.
• Extreme Pressure Rating: Rated for a maximum working pressure of 46 bar (667 psig), making it suitable for modern high-pressure refrigerant applications.
• Corrosion Resistance: Finished with a powder-painted shell that passes 500-hour salt spray testing, ensuring durability in harsh environments.
• Technical Precision: Steel Cu-plated solder connections facilitate reliable, leak-proof integration into 10mm ODF liquid lines.

Common Questions:

Is this drier compatible with R22 systems?
Yes, while optimized for HFCs, the Danfoss DML series is fully compatible with HCFC refrigerants like R22 and is safe for use with mineral or alkylbenzene oils.

What is the directional flow for the 023Z4827?
This is a one-way filter drier. Installation must follow the flow direction arrow printed on the label to ensure effective filtration and moisture removal.

Can I use this for suction line protection?
No, the DML 053S is specifically designed for liquid line protection. Suction line models should be used for compressor burnout cleanup or low-side protection.
