Adsorption Dryer

  1. Fast drying, and standard gas can be provided within minutes after
  2. One-Click start, which can realize unattended
  3. Using highly active molecular sieve, gas dew point operation is more stable
  4. Low dew point pressure, flow rate of gas,adjustable to meet different requirements
  5. Reasonable design, compact, stability, small energy consumption
  6. CPU integrationcontrol, which can realize full automatic operation

The principle of the adsorption dryer is to take advantage of the difference in volume between water and air molecules in saturated compressed air, and use highly active molecular sieves to filter out saturated water vapor in the compressed air. Water molecules can be easily adsorbed within the molecular sieve particles, and then the molecular sieves can be restored through a cycle of regeneration. Since the adsorbent will reach saturation equilibrium within a certain period of time, it is necessary to regenerate it with dry gas to restore the adsorption drying effect. The adsorption dryer uses two towers to operate alternately. It utilizes its own drying gas and reduces the pressure to close to atmospheric pressure to serve as regenerative gas for the regeneration and drying of the other tower. The two towers switch at the set switching time, thereby continuously providing dry compressed gas. The dew point of the compressed air can be maintained at -40℃ or higher.
