 Model,Size&Technical Data:

How it works:

Heatless Purge Desiccant Air Dryer is using micro holes in the desiccant itself,adsorbing the moisture in the air because of capillary,desorbing it by pressure drop and adsorbing extra-heat.Currently,the equipment is making up of two towers,controlled by the Program Controller,the two towers working alternately,one is for adsorbing,the other is for desorbing,in the way continually circulating the work.

 Product Character:

Consistent outlet pressure dew points

Rationalizing tower layout,ensure 4.8 second contact time enough to dry saturated air at the dryer inlet to the desired dew point.

30% extra desiccant provide to compensate for natural bed aging,ensure top performance of desiccant bed.

Large flow diffusers ensure even flow distribution through bed,eliminates channeling.

Minimum purge air use according to the less than 13.3%

Excellent designing tower,saves 95% of the heat of adsorption,stored heat maintains purge air temperature during regeneration,maximizing the purge air’s ability to carry off moisture,minimizing the amount of purge air required.

Drying and purging in counter flow arrangement,energy not be wasted when wet air travels through dry desiccant.

You can adjust purge air use according to the demand.

Long desiccant life

A.Suitable tower sized ensure best condition of velocity & time when compressed air through desiccant bed,making good use of the desiccant.

B.Rationalizing system,remove oil and heavy contaminants before flowing into the tower,protects bed from contamination.

*Using butterfly value and reliable program controller which can be auto timing and auto switching,works stable and reliable,unaffected from electric net,pressure and electric field.

*Scientifically designed switching time ensuring the air pressure being stable,running without waving.

*Non basement,easy to install
