When moist air passes through the adsorbent of the wheel, water molecules are adsorbed and removed, making the air dry. The processed dry air passes through the condenser, and the water vapor is condensed into water and discharged outside the machine, while the remaining dry air is discharged through the air outlet.

The working principle of the desiccant wheel of the dehumidifier is to use the desiccant inside the wheel for dehumidification. The impeller is made of special composite high-temperature resistant materials and is divided into two fan-shaped areas, one for handling wet air and the other for regenerating air.
