Adsorption Air Dryer also called Desiccant Air Dryer, is an air drying equipment, which works with air compressor and air filters to get the dried and purified compressed air. It drys the compressed air by PSA and TSA means.



Heatless Desiccant Air Dryer is using micro holes of the desiccant/adsorbent, adsorbs the moisture of the compressed air; meanwhile desorbs it by pressure relief and adsorbs the extra-heat, which are known as PSA(Pressure Swing Adsorption) and TSA(Temperature Swing Adsorption). Currently, the equipment is making up of two towers,controlled by the Program Controller, the two towers work alternately,one is for adsorbing, the other is for desorbing, continually circulating the running.



Consistent outlet pressure dew points.
A. Rationalizing tower layout, ensure 4.8 second contact time enough to dry saturated air at the dryer inlet to the desired dew point.
B. 30% extra desiccant provide to compensate for natural bed aging, ensure top performance of desiccant bed.
C. Large flow diffusers ensure even flow distribution through bed, eliminates channeling.
Minimum air loss <13.3%.
A. An excellent column design,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.
B. Drying and regeneration in counter flow arrangement, energy not be wasted when wet air travels through dried desiccant.
C. You can adjust regeneration air 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, a filter installed will remove oil and heavy contaminants before air flows into the tower, protects bed from contamination.
Superior quality.
A. Using butterfly valve and reliable program controller which can be auto timing and auto switching, works stable and reliable, unaffected from electric net, pressure and electric field.
B. Scientifically designed switching time ensuring the air pressure being stable,running without waving.
C. Non basement,easy to install.
Standard adsorption air dryer designed data: Inlet pressure: 7bar, Inlet temperature: ≤38℃. If inlet pressure are different, Capacity=Compressor FAD÷(table-1)
