Danfoss 023Z5064 Filter Drier
The Danfoss 023Z5064, professionally known as the DML163S liquid line filter drier, is an essential component for high-pressure refrigeration systems utilizing HFC, HCFC, and CO2 refrigerants. This unit features 3/8" ODF solder connections and a 16-cubic-inch solid core comprised of 100% molecular sieve material. Unlike alumina-blend cores, this pure molecular sieve construction is optimized for maximum moisture adsorption in systems using polyolester (POE) or polyvinyl ether (PVE) oils, which are highly hygroscopic. The Danfoss DML163S effectively prevents acid formation and prevents expansion valve freeze-ups by maintaining extremely low moisture levels across the liquid line. Built with a powder-coated finish for superior corrosion resistance and tested for a maximum working pressure of 667 psig (46 bar), this 023Z5064 filter drier ensures reliable debris filtration and system dehydration for light commercial AC and refrigeration applications.
Key Benefits for Technicians:- 100% Molecular Sieve core provides industry-leading water capacity, critical for protecting sensitive POE lubricants.
- High pressure rating of 667 psig makes it a versatile choice for R-410A, R-404A, and high-pressure R-134a systems.
- Minimal pressure drop design ensures the system maintains peak volumetric efficiency without starving the metering device.
- Solid core construction captures solid contaminants down to 25 microns while resisting core disintegration under vibration.
- Compact 163 series footprint allows for straightforward drop-in replacement in tight evaporator or condenser sections.
Is the Danfoss 023Z5064 compatible with older HCFC systems?
Yes, while optimized for HFCs and POE oils, the 100% molecular sieve core is fully compatible with R-22 and mineral oil-based systems without risk of additive stripping.
Can the DML163S be used in bidirectional heat pump applications?
No, the DML163S is a unidirectional drier. In a heat pump circuit where flow reverses, you must install two driers with check valves or a dedicated DCL series bi-flow drier.
What is the difference between the 023Z5064 and a DCL drier?
The 023Z5064 (DML) uses a 100% molecular sieve core for moisture removal, whereas the DCL series contains 20% activated alumina for acid neutralization. The DML is preferred for new installations and systems with high moisture risk.
