Working Principle of Low Dew Point Desiccant Dehumidifier
The Low Dew Point Desiccant Dehumidifier uses a honeycomb desiccant rotor as the core moisture removal component.
When process air passes through the rotor, moisture molecules are absorbed by the desiccant material, producing dry air with low humidity levels for the production area.
As the rotor continuously rotates into the regeneration zone, heated regeneration air removes the absorbed moisture and exhausts it outside the system. The rotor is then regenerated and ready for continuous operation.
By precisely controlling regeneration temperature, rotor speed, and airflow balance, the system can maintain stable ultra-low dew point performance for 24-hour continuous operation.
