Danfoss DML 163 Hermetic Filter Drier | 16 cu.in. | 3/8 in Flare
Product Description
The Danfoss DML (023Z504591) is a robust protection solution specifically tailored for the demanding Middle Eastern HVAC/R market. Equipped with a 16 cubic inch solid core of 100% Molecular Sieve, it delivers exceptional adsorption capacity, ensuring that refrigerants and sensitive POE oils remain dry even under the intense summer heat of the UAE. Its 3/8 in flare connections facilitate secure and efficient installation in commercial refrigeration units. The high-grade steel body is finished with a corrosion-resistant powder coating, making it ideal for the saline and humid atmospheres found in UAE coastal regions. This “91” industrial variant is the trusted choice for large-scale maintenance operations in Dubai, aiming to prevent acid formation and compressor failures.
Key Features & Benefits:
- Industrial Moisture Protection: 100% molecular sieve core is optimized for HFC/HFO refrigerants common in UAE commercial plants.
- Corrosion-Resistant Steel Build: Specifically coated to withstand the harsh, salty ambient conditions of coastal Dubai and Abu Dhabi.
- High Working Pressure: Rated for up to 46 bar, making it safe for high-pressure R410A and R32 systems used across the UAE.
- Acid Neutralization Efficiency: By keeping moisture at near-zero levels, it effectively prevents chemical breakdown and acid-related wear in UAE compressors.
- Hermetic Reliability: Precision laser-welded construction guarantees a leak-proof service life, vital for high-efficiency UAE infrastructure.

FAQs:
- Q: Is there a difference in specs between 023Z504591 and 023Z5045?
- A: Technical performance is identical; however, the “91” suffix denotes an industrial bulk packaging format preferred by major UAE service contractors.
- Q: Why is a 100% Molecular Sieve core important for UAE heat?
- A: Unlike alumina-based cores, DML won’t release moisture back into the system even when the liquid line gets very hot in the UAE.
- Q: Can this drier be used with R134a in Dubai?
- A: Absolutely. It is fully compatible with R134a, R404A, R407C, R410A, and many others used in the UAE.
