Danfoss 023Z1649 Filter Drier
The Danfoss 023Z1649 DMB 164 is a solid core bi-flow filter drier engineered specifically for heat pump systems and reversible refrigeration cycles. Featuring a high-capacity 16 cubic inch core composed of 100% molecular sieve material, this drier excels at moisture absorption and acid neutralization, protecting sensitive components like the expansion valve and compressor. The bi-flow design utilizes internal check valves to ensure refrigerant is filtered in both heating and cooling modes while maintaining low pressure drop across the system. It is fully compatible with modern HFC refrigerants including R-410A, R-407C, and R-134a, as well as POE or PAG oils. The 1/2-inch flare connection ensures a secure, leak-free mechanical joint during field installation. Rated for a maximum working pressure of 667 psig (46 bar), this liquid line filter drier provides the durability required for high-pressure heat pump applications where consistent refrigerant filtration is critical for long-term system reliability.
Key Benefits for Technicians- Bi-Flow Functionality: Internal check valves eliminate the need for external piping work in reversible cycles, simplifying heat pump repairs.
- High Dehydration Capacity: The 100% molecular sieve core provides maximum water removal to prevent ice formation and acid buildup.
- Durable Construction: Corrosion-resistant epoxy powder paint finish passes the 500-hour salt spray test for longevity in harsh environments.
- System Protection: Effectively captures solid contaminants down to 25 microns without restricted flow or significant capacity loss.
- Verified Compatibility: Optimized for high-pressure R-410A systems and multi-refrigerant use in commercial and residential HVACR.
Does this drier require a specific orientation?
While the 023Z1649 is bi-directional, it is best practice to install it in the liquid line where the refrigerant remains in a liquid state to ensure optimal moisture capture through the desiccants.
Is the DMB 164 suitable for R-22 systems?
Yes, while highly effective for HFCs and POE oils, the 100% molecular sieve core is also compatible with HCFC refrigerants like R-22 and mineral oils.
What is the purpose of the flare connection on this model?
The flare fittings allow for rapid replacement without the need for a torch, which is advantageous in environments where open flames are restricted or when protecting sensitive internal check valves from excessive heat.
