Working Principle
The dehumidifier uses separate process air and reactivation air circuits for continuous moisture removal.
- Process Air: Humid air passes through the G4 filter and desiccant wheel. Moisture is adsorbed, and the process air fan delivers dry air through the outlet.
- Reactivation Air: Fresh air passes through a separate G4 filter and is heated before entering the regeneration section of the wheel.
- Moisture Exhaust: The reactivation fan carries released moisture out through the regeneration air outlet.
- Continuous Regeneration: The rotating wheel continuously switches between adsorption and regeneration, maintaining stable dehumidification.
