Danfoss 023Z5033 Filter Drier

The Danfoss 023Z5033 is a high-performance liquid line filter drier engineered for HVACR refrigeration systems requiring reliable moisture and acid removal. Featuring a 5/8" ODF solder connection, this DML 305S model utilizes a 100% molecular sieve core, making it specifically optimized for HFC refrigerants such as R134a, R404A, R410A, and R507. Its high adsorption capacity ensures maximum protection for the thermal expansion valve (TXV) and compressor by preventing ice formation and neutralizing harmful contaminants. The solid core design minimizes pressure drop while providing superior filtration down to 25 microns. Constructed with a corrosion-resistant powder-painted finish and rated for a Maximum Working Pressure (MWP) of 667 psig (46 bar), this unit maintains system stability across a wide temperature range of -40°F to 160°F. For contractors, the 023Z5033 provides a robust solution for maintaining deep dehydration and chemical stability in commercial cooling applications.

• High Adsorption Capacity: The 100% molecular sieve core provides maximum water removal to prevent system acidification and component corrosion.
• Optimized Compatibility: Specifically designed for HFC refrigerants and POE or PVE lubricants, ensuring chemical compatibility without binder depletion.
• Durable Construction: Features a high-pressure rated steel shell with UL and CE certification for demanding field conditions.
• System Protection: Effective filtration prevents debris from clogging orifice plates and expansion valves, reducing nuisance service calls.

What is the difference between Danfoss DML and DCL filter driers?
The DML series, like the 023Z5033, uses a 100% molecular sieve core for maximum moisture removal in HFC systems. The DCL series contains 20% activated alumina for acid adsorption in systems using HCFC or CFC refrigerants with mineral oils.

Is the 023Z5033 bi-directional?
No, this is a liquid line filter drier designed for uni-directional flow. Ensure the flow arrow on the housing points toward the expansion device during installation.

What is the best brazing practice for this ODF connection?
Use a wet rag or heat sink paste on the drier body to prevent overheating the internal core or damaging the paint seal while brazing the 5/8" sweat connections.
