Danfoss 023Z5044 Filter Drier

The Danfoss 023Z5044 DML 164 is a solid core liquid line filter drier engineered specifically for high-pressure applications utilizing HFC refrigerants such as R410A, R134a, and R404A. Operating with a 100% molecular sieve core, this unit provides maximum moisture adsorption capacity even at high liquid temperatures, effectively preventing the formation of harmful acids within the system. Designed with 1/2-inch flare connections, it ensures a secure, leak-free installation for commercial refrigeration and air conditioning circuits. The DML 164 is rated for a Maximum Working Pressure (MWP) of 46 bar (667 psig), making it a reliable component for modern high-pressure systems. Its high-grade steel shell undergoes a corrosion-resistant powder paint finish, verified through a 500-hour salt spray test. This 16-cubic-inch capacity drier is optimized for rapid dehydration and debris filtration, ensuring that the expansion valve (TXV) remains free of contaminants, thereby maintaining peak system efficiency and preventing premature compressor failure.

• 100% Molecular Sieve Core: Optimized for HFCs and POE/PAG oils, providing superior moisture removal compared to activated alumina cores.
• High Pressure Protection: UL listed for MWP up to 667 psig, essential for R410A refrigerant cycles.
• Minimized Pressure Drop: Internal design allows for high flow rates while maintaining high debris retention capacity.
• Durable Construction: Features a corrosion-resistant finish and robust steel body for longevity in harsh environments.
• Precise Filtration: Effectively traps particulates down to 25 microns to protect sensitive metering devices.

What is the difference between Danfoss DML and DCL series?
The DML series uses a 100% molecular sieve core designed for HFCs and synthetic oils. The DCL series contains 20% activated alumina, making it better suited for HCFC/CFC refrigerants and mineral oils where acid removal is the primary concern.

Can the DML 164 be installed in any orientation?
While vertical installation with the flow pointing downward is preferred for optimal drainage, the DML 164 can be installed horizontally. Always ensure the flow arrow matches the direction of the liquid line.

Does this filter drier protect against burnouts?
The DML is a liquid line drier for moisture and particle removal during normal operation. After a compressor burnout, a dedicated suction line drier with activated alumina should be used in conjunction with the liquid line drier.
