Working Principle
1. Process Air Drying
Humid air is filtered, driven by the process fan, and passed through the desiccant wheel to remove moisture.
2. Dry Air Delivery
The treated low-humidity air is discharged through the process air outlet.
3. Reactivation Air Heating
A separate reactivation air stream is filtered and heated before entering the regeneration section of the wheel.
4. Rotor Regeneration
The heated air removes stored moisture from the desiccant material.
5. Moisture Exhaust
The regeneration fan discharges the moisture-laden air outside, allowing the wheel to continuously repeat the drying cycle.
