There are two types of air dryers: desiccant air dryer and refrigerated air dryer. The desiccant air dryer uses the principle of pressure swing adsorption. When the wet air passes through the adsorbent, the moisture is adsorbed to obtain dry air; The water is separated from the air by condensation to obtain dry air.


• 10 minutes cycle in the desiccant dryers.

• The pressure dew point of the desiccant dryers can reach - 20 ℃ to - 40 ℃;

• Regeneration gas consumption ≤ 14%;

• High-quality switching valve in the stable and reliable, can ensure the integrity of the working process, prolong the working life of components;

• The activated alumina with high hygroscopicity is selected in the Heatless Desiccant Air Dryer, with uniform shape and size, high strength, high dew point, less dust,
  and long service life;

• The amount of regeneration gas can be adjusted according to the operation load demand of the equipment to achieve energy-saving effect;

• Special airflow diffusion device and automatic regeneration in the desiccant dryers, ensure the service life of desiccant;

• Programmable microcomputer controller, adsorption, regeneration working time can be adjusted to achieve your satisfactory dew point value.
