How Do Desiccant Dehumidifiers Work?
Desiccant dehumidifiers use a rotating desiccant wheel to capture moisture from humid air. As the rotor turns, one side absorbs water vapor, while the other side is regenerated by heated air for continuous moisture removal.
Humid Air Intake: Moist process air is drawn into the unit through the process air inlet.
Desiccant Rotor Drying: Process air passes through the desiccant rotor, where moisture is absorbed to reduce humidity.
Dry Air Supply: The dried air exits the rotor and is supplied to the room, ductwork, or production area.
Reactivation Heating: Heated reactivation air flows through another rotor section to remove the absorbed moisture.
Moisture Exhaust: The moisture-laden air is discharged from the unit, allowing the rotor to continuously repeat the drying cycle.
