Danfoss DML 164 Hermetic Filter Drier | 1/2 in Flare | 023Z5044

Product Description: The DML 164 (023Z5044) is engineered to provide the highest level of drying capacity. In the UAE’s high-humidity coastal environments, moisture in the refrigeration circuit can lead to acid formation and compressor failure. The DML series solves this with a solid core of 100% 3Å molecular sieve, which adsorbs water without depleting the essential oil additives found in HFC refrigerants like R134a, R404A, and R410A. This model features a 16 cubic inch core and 1/2 inch flare connections, making it a versatile choice for both new installations and field repairs in Dubai’s commercial cooling and residential HVAC sectors.

Key Features & Benefits:

• 100% Molecular Sieve Core: Provides maximum moisture adsorption capacity, ensuring the system remains dry even in the challenging Middle Eastern climate.
• No Oil Additive Depletion: Because it contains no activated alumina, it protects the chemical integrity of POE and PAG oils used in modern HFC systems.
• High Dirt Retention: Features a 25 $\mu$m filter that effectively traps solid particles with minimal pressure drop, safeguarding expansion valves and capillary tubes.
• Corrosion Resistant Shell: The steel housing is finished with a powder-painted coating, offering durability against the saline air and humid conditions of the UAE.
• Bi-flow Compatibility: Can be installed in any orientation (following the flow arrow), allowing for flexible installation in tight mechanical spaces.

FAQs:

• Q: Why use DML instead of DCL in the UAE?
• A: DML (100% molecular sieve) is recommended for systems using HFC/HFO refrigerants and POE/PAG oils where high moisture capacity is the priority. DCL is better for older systems using mineral oil that require acid adsorption.
• Q: Does the 023Z5044 handle R410A high pressures?
• A: Yes, it is rated for a maximum working pressure of 46 bar (667 psig), making it fully compatible with R410A systems common in Dubai.
• Q: Can this filter drier be cleaned and reused?
• A: No, this is a hermetic (sealed) unit. Once it is saturated or the system is opened for major repairs, it must be replaced to ensure system purity.
