Dry rooms

Product feature

● Pharmaceutical materials such as powders, tablets, capsules, and suppositories are highly susceptible to deterioration and failure after absorbing moisture. Rotary dehumidifiers prevent corrosion, reduce damage to electronic products, and inhibit bacterial growth, creating a suitable storage environment for equipment. Therefore, rotary dehumidifiers are commonly used in dry rooms or cleanrooms for professional humidity control.

The core component of a rotary dehumidifier is a honeycomb-shaped rotor made of a special ceramic fiber carrier and activated silica gel. The rotor is divided into two areas by a specially designed sealing device: a treatment area and a regeneration area. When humid air needs dehumidification, it passes through the treatment area of ​​the rotor. The water vapor in the humid air is adsorbed by the activated silica gel on the rotor, and the dry air is then delivered to the space requiring treatment by the processing fan. Meanwhile, the slowly rotating rotor, carrying nearly saturated water vapor, enters the regeneration area. In the regeneration area, high-temperature air blown in the opposite direction desorbs the adsorbed moisture from the rotor, which is then discharged outdoors by the fan. This restores the rotor's moisture absorption capacity, completing the regeneration process. The rotor rotates continuously, and the above dehumidification and regeneration cycle repeats continuously, ensuring a stable dehumidification state for the dehumidifier.

Water molecules in the air are absorbed by the hydrophilic groups in the silica gel micropores. Additionally, condensation in the capillary structure within the micropores also absorbs a large number of water molecules. Heated air enters the regeneration zone, raising its temperature. This activates the water molecules adsorbed in the micropores, weakening their adsorption capacity, and causing them to escape from the silica gel micropores.
