Desiccant Air Drying Technologies

Desiccant dryers work on the principle of moisture always migrating to the driest medium possible. Therefore, water vapour is removed from compressed air by passing it over an adsorbent desiccant material. In the above shown CompAir air treatment product family image, the desiccant dryer is shown in the centre by the twin towers & these types of air dryers can cater for larger airflow volumes. The full range of desiccant dryers is shown below. As the air contacts the adsorbent material, water vapour transfers from the wet air to the dry desiccant, however, adsorbent materials have a fixed adsorption capacity and once this capacity is reached, they must be regenerated or replaced.
