  AHU Configuration & Components

  Main AHU Components

  • Fresh Air / Return Air Section
    Controls the introduction and recirculation of air according to the HVAC design.
  • Pre-Filtration Section
    Removes larger airborne particles before air enters the finer filtration stages.
  • Cooling Coil
    Removes sensible and latent heat from the air. It can be connected to a chilled-water system or other specified cooling source.
  • Heating Section
    Provides heating when required for temperature control or winter operation.
  • Humidification / Dehumidification
    Configured when the cleanroom process requires tighter humidity control.
  • Fan Section
    Provides the required airflow and static pressure for the downstream air distribution system.
  • HEPA Filtration
    Can be incorporated where the system design requires high-efficiency final filtration.
  • Control Section
    Monitors and regulates operating parameters such as temperature, humidity, fan status, and differential pressure.

  Cleanroom Air Distribution

  HEPA filter location depends on the cleanroom HVAC design. In some systems, final HEPA filtration is installed at the terminal FFU or ceiling level rather than directly inside the AHU

  Temperature & Humidity Control

  ---

  The AHU can be configured to support temperature and humidity control through cooling coils, heating sections, humidification and dehumidification functions. Control parameters are selected according to the cleanroom process, product requirements, outdoor conditions and HVAC design.

  • Supply air temperature
  • Return air temperature
  • Relative humidity
  • Cooling coil
  • Heating coil
  • Humidifier
  • Dehumidification
  • Sensors
  • PLC/HMI

  HVAC System Integration

  ---

  The Clean Room AHU can be integrated with:

  • Chilled Water Chiller
  • Chilled Water Pumps
  • Cooling Towers, where applicable
  • Ductwork
  • HEPA Filters
  • FFUs
  • Cleanroom Terminal Units
  • Differential Pressure Monitoring
  • Temperature & Humidity Sensors
  • BMS

  The AHU primarily conditions and supplies air, while terminal filtration and airflow distribution are determined by the overall cleanroom HVAC design.

  Engineering & Selection Process

  ---

  Engineering & Selection Process

  • 1. Requirement Analysis
    Review cleanroom classification, room volume, occupancy, process heat load, outdoor air requirements, temperature and humidity targets.
  • 2. Airflow Calculation
    Determine supply and return airflow based on room requirements, air-change strategy, pressure relationships and process requirements.
  • 3. AHU Selection
    Select airflow capacity, static pressure, cooling/heating capacity, filtration stages, fan type and control configuration.
  • 4. System Integration
    Coordinate AHU with chillers, pumps, ductwork, HEPA filters, FFUs, sensors and BMS.
  • 5. Manufacturing
    Manufacture the AHU according to the approved configuration and technical specifications.
  • 6. Testing & Commissioning
    Perform applicable factory inspection and support on-site commissioning according to the project scope.

  Pharmaceutical Cleanroom Project – Mauritius

  • Application: Pharmaceutical manufacturing
  • Scope: HVAC system design / AHU integration / installation support
  • Country: Mauritius

  Exceptional Air Filtration Capability

• Stringent Airflow & Pressure Differential Control
• Precise Temperature & Humidity Control
• Superior Airtightness & Construction Materials
• Energy Efficiency & Heat Recovery

Typical System Configuration&Workflow

1. 1. Outside Air Pretreatment Section: Provides initial filtration and conditioning (temperature/humidity) for outside air, sometimes incorporating energy recovery from exhaust air.

   2. Mixing Section: Outside air and cleanroom return air are mixed in a controlled ratio.

   3. Temperature & Humidity Conditioning Section:

      • Cooling Coil: Uses chilled water for cooling and dehumidification.

      • Heating Coil: Uses hot water or electric elements for heating.

      • Humidification Section: Injects clean steam.

   4. Fan Section: A draw-through configuration (fan located after the coils) is more common, placing the coil section under negative pressure to prevent condensate leakage. Fans are typically VFD-controlled.

   5. Intermediate & Flow Straightening Sections: Ensure even airflow distribution across filters.

   6. Filtration Section: Houses medium-efficiency filters.

   7. Acoustic Attenuation Section: Reduces noise generated by high-volume fans.

   8. Discharge Section: Connects to ductwork leading to HEPA/ULPA filter fan units or ceiling terminals in the cleanroom.

   9. Control System: The central brain, often using DDC/PLC, which integrates with room sensors (temperature, humidity, pressure) to enable automated regulation.

Engineering Process

• Requirement Analysis
  Review airflow, cooling/heating load, filtration and cleanroom requirements.
• AHU Configuration
  Select casing, filters, coils, fans and control components according to project specifications.
• Manufacturing & Inspection
  Assemble and inspect the AHU before shipment.
• Installation & Commissioning
  Support installation, airflow adjustment and system commissioning.
• Testing & Documentation
  Provide applicable testing records, operation manuals and project documentation.
