DMT hermetic filter driers for CO₂

Product store

The pressure rating is 140 bar

The DMT filter drier is specially designed to cope with the high standstill and working pressures of a transcritical CO₂ refrigeration system. The pressure rating is 140 bar (2031psig) and meets the toughest international pressure equipment standards including the EN378-2.

Designed to adsorb moisture and prevent acid formation, the DMT filter drier has 100% molecular sieve solid core, which offers one of the fastest drying velocities available.

In addition to the molecular sieve, the DMT is complete with a polyester filter mat capable of filtering impurities down to 25 microns, with minimal pressure drop. The product is often seen installed in the oil return line of CO₂ systems combined with High Pressure VDHT valves. The hermetic DMT filter drier has a corrosion-resistant surface coating. 

Features and benefits

  • High drying capacity minimizing the risk of acid formation (hydrolysis)

  • 25 μm (0.001 in.) filter provides high retention with minimal pressure drop

  • Available in sizes from 8 to 13 cubic inches

  • Available with solder (copper plated) and flare connections (standard and NPT)

  • Black paint gives a better look after brazing installation
