Working Principle
- Air Intake & Filtration: Process and reactivation air pass through separate G4 filters for cleaner airflow.
- Moisture Adsorption: The process fan forces humid air through the desiccant wheel, where moisture is adsorbed.
- Dry Air Supply: Dehumidified air leaves the wheel through the process air outlet.
- Wheel Regeneration: Heated reactivation air removes accumulated moisture from the desiccant wheel.
- Moisture Exhaust: The reactivation fan discharges moisture-laden air outside.
- Continuous Drying: Continuous wheel rotation enables simultaneous adsorption and regeneration.
