Air Treatment Process of the Dehumidification AHU System
The industrial AHU system was designed to provide complete air treatment through cooling, dehumidification, filtration, and controlled air distribution.
The air handling process follows a multi-stage treatment sequence to achieve stable indoor environmental conditions.
- Outdoor fresh air enters the AHU system
- G4 pre-filter removes large dust particles
- F8 filter provides higher efficiency particle filtration
- Chilled water cooling coil reduces air temperature
- Rotary desiccant wheel removes moisture from the air
- Post cooling adjusts supply air temperature
- H10 filter provides final air purification
- Conditioned dry air is supplied to the production area
This integrated air treatment process allows the system to control both temperature and humidity, which is essential for industrial applications operating in tropical climates.
Rotary Desiccant Dehumidification Technology
The core technology of this project is the rotary desiccant dehumidification system.
Unlike conventional cooling-based dehumidification, a desiccant rotor removes moisture through moisture adsorption, allowing efficient humidity control even under high humidity conditions.
-
Moisture Absorption
The desiccant rotor absorbs moisture from the process air stream. -
Continuous Rotor Rotation
The rotating wheel continuously moves between process and regeneration sections. -
Moisture Release
The regeneration section removes absorbed moisture using heated air. -
Dry Air Supply
Low-humidity air is delivered to the industrial production environment.
This technology is particularly suitable for factories where humidity control directly affects production quality, storage conditions, or equipment reliability.
Chilled Water Cooling System Design
The AHU system uses chilled water cooling coils to provide efficient temperature control before and after the dehumidification process.
The dual cooling coil configuration improves system performance by separating cooling and moisture control functions.
Pre-Cooling Coil
The pre-cooling section reduces incoming air temperature and prepares the air for efficient moisture removal through the desiccant rotor.
Post-Cooling Coil
After dehumidification, the post-cooling coil adjusts supply air temperature to achieve comfortable and stable indoor conditions.
- Stable cooling performance
- Improved humidity control efficiency
- Flexible connection with central chilled water systems
- Suitable for large industrial applications
- Easy integration with factory HVAC infrastructure
Multi-Stage Air Filtration System
Industrial environments often require higher air cleanliness standards than ordinary commercial buildings.
The project uses multiple filtration stages to improve supplied air quality.
| Filter Stage | Function |
| G4 Pre Filter | Removes large dust particles and protects downstream components |
| F8 Fine Filter | Captures smaller airborne particles and improves air cleanliness |
| H10 Final Filter | Provides final-stage filtration for higher indoor air quality requirements |
The multi-stage filtration design helps protect production environments while extending the service life of internal HVAC components.
Industrial Fan and Airflow Design
Reliable airflow performance is essential for large industrial HVAC systems.
The project uses industrial centrifugal fans with variable frequency drive (VFD) control to achieve flexible airflow adjustment.
- Adjust airflow according to production requirements
- Reduce unnecessary energy consumption
- Maintain stable air pressure
- Improve operating flexibility
- Support intelligent HVAC control strategies
Industrial Reliability Design
Industrial HVAC systems must operate reliably under continuous working conditions.
YUJU considered multiple factors during system development to ensure long-term performance.
- Heavy-duty AHU structure
- High-efficiency air treatment components
- Easy maintenance access
- Industrial-grade fan selection
- Stable humidity control performance
- Customized system configuration
The final solution provides a reliable indoor climate system capable of supporting demanding industrial production environments.

Why Industrial Dehumidification Requires Professional Engineering
Industrial humidity control is more complex than ordinary air conditioning because temperature and moisture must be controlled independently.
Simply increasing cooling capacity does not always solve humidity problems, especially in tropical climates with high outdoor moisture levels.
Professional industrial HVAC design requires evaluation of:
- Outdoor climate conditions
- Indoor production requirements
- Humidity target range
- Airflow requirements
- Heat and moisture loads
- Filtration standards
- Energy consumption goals
