Danfoss 023Z5035 Filter Drier

The Danfoss 023Z5035 DML032 is a high-performance liquid line filter drier designed for HFC refrigerants and synthetic polyolester (POE) or polyalkylene glycol (PAG) oils. Utilizing a 100% molecular sieve core, this unit provides maximum moisture adsorption capacity, which is critical for protecting the expansion valve from ice formation and preventing acid buildup that leads to compressor burnout. The DML032 features 1/4 inch flare connections (SAE) and is engineered with a high-strength powder-coated finish for superior salt spray resistance in demanding environments. This hermetic filter drier is optimized for systems requiring high drying capacity at both low and high liquid temperatures. Its solid core design ensures minimal pressure drop and effective solid particle filtration down to 25 µm. For technicians servicing systems with R410A, R134a, or R404A, the Danfoss 023Z5035 provides reliable refrigeration system protection without specialized installation tools, ensuring long-term system stability and performance.

• High Drying Capacity: The 100% molecular sieve core ensures maximum water removal, protecting POE oils from hydrolysis.
• Universal Compatibility: Rated for use with high-pressure refrigerants including R410A and R32, with a maximum working pressure (MWP) of 46 bar (667 psig).
• Debris Protection: Effective 25 µm filtration prevents circulating contaminants from clogging the orifice of the thermal expansion valve.
• Corrosion Resistance: Durable powder-painted exterior withstands 500 hours of salt spray testing, ideal for coastal or industrial installs.
• Versatile Application: Compact 03-cubic inch housing fits easily into tight liquid line configurations in residential and light commercial systems.

Is the Danfoss 023Z5035 compatible with R22 systems?
While the DML series is optimized for HFCs and POE oils, it can be used in HCFC systems; however, for systems using mineral oil or ALK, the Danfoss DCL (composite core) series is often preferred to handle acid neutralization alongside moisture removal.

What is the difference between Danfoss 023Z5035 and DML032?
They are the same product. The 023Z5035 is the specific ordering code for the DML032 model featuring 1/4" flare connections.

Can this filter drier be installed in either direction?
No, the DML032 is a mono-flow filter drier. Ensure the arrow on the label points in the direction of refrigerant flow toward the expansion device.
