Danfoss 023Z5043 Filter Drier

The Danfoss 023Z5043 (DML 163) is a high-capacity liquid line filter drier engineered specifically for systems utilizing HFC refrigerants and polyolester (POE) or polyalkylene glycol (PAG) oils. Featuring a 100% molecular sieve core (3Å), this unit provides maximum moisture adsorption to prevent the hydrolysis of POE oils and subsequent acid formation. This 16 cubic inch solid core design is the industry standard for refrigeration and air conditioning systems requiring superior dehydration capabilities without sacrificing flow rates. With a 3/8" flare connection and a 46 bar (667 psig) maximum working pressure, the Danfoss DML 163 is a direct replacement for 023Z504300 and DML163. Its hermetic filter drier construction features a powder-painted steel shell that has undergone 500-hour salt spray testing, ensuring durability in harsh environments. The internal design includes a 25 µm filter pad to trap solid contaminants while maintaining a low pressure drop, making it an essential component for maintaining HVACR system longevity and efficiency.

• 100% 3Å Molecular Sieve: Optimized for HFCs like R410A, R134a, and R404A, providing the highest moisture capacity available for modern oils.
• High Dirt Retention: Integrated 25-micron filter provides effective particle removal to protect expansion valves and compressors.
• Corrosion Resistant: One-piece steel shell with a durable powder coating allows for installation in demanding commercial or marine applications.
• Universal Compatibility: Designed for high condensing temperatures and compatible with most HCFC and HFC refrigerants.

• What is the difference between DML and DCL series? While both provide filtration, the DML (023Z5043) uses a 100% molecular sieve core for maximum moisture removal. The DCL series includes activated alumina for acid adsorption, typically used in older systems with mineral oils.
• Is the 3/8" connection solder or flare? This specific model (023Z5043) features 3/8-inch flare (SAE) connections for quick, reliable mechanical fitting.
• Can this be used for R22 systems? Yes, the 100% molecular sieve core is compatible with R22 as well as modern HFC replacements.
