Combined Air Dryers

Combination air dryer is a new kind of compressed air treatment product which consists of refrigeration and adsorption unit. The refrigeration unit can remove about 85% of moist air while the adsorption unit removes the other portion of moist water, the final dew point can reach to -70℃.

Combination air dryer utilizes the respective advantage of refrigerated and adsorption air dryer. The most portion of water is removed by refrigeration unit, thus reduce the load of adsorption unit.

Features

Dew point as low as -50~ -70℃

The lifetime of desiccant can be extended by 3 triple  reduce the maintain cost.

Purge loss is only 3%,thus greatly reduce the energy cost.

Skid mounted design, easy for installation

PIC controller to achieve automatic control
