Large Capacity AHU for HVAC Systems Airflow 2000-70000 and Operating Voltage 380/400 VAC

Product Overview

Air Handling Unit

Features at a Glance

• Centralized Processing & Unified Control

  • Core Advantage: Consolidates all critical air treatment processes—filtration, temperature/humidity conditioning, and distribution—into a single, integrated unit. This eliminates the redundancy and management complexity of decentralized systems.

  • Value Delivered: Enables unified, standardized control over the indoor environment of a building or zone, leading to higher management efficiency and enhanced system stability and reliability.

•  Precise Environmental Control

  • High-Precision Regulation: Capable of independently and precisely controlling temperature, humidity, cleanliness (via filtration grade), and air pressure. This precision far exceeds that of standard residential or commercial split systems.

  • Mission-Critical Application: This is essential for meeting the stringent environmental requirements of industrial manufacturing, laboratories, cleanrooms, and high-end commercial spaces. It reliably enables constant temperature/humidity conditions and maintains critical positive/negative pressure differentials.

•  Flexible Configuration & High Adaptability

  • Modular Design: Especially true for built-up AHUs, which can be configured like "building blocks." This allows for the flexible selection of functional sections (e.g., different filter grades, heating/cooling methods, humidifier types, fan types) based on specific project needs.

  • Broad Applicability: Through varied configurations, AHUs can serve a wide range of applications—from standard office buildings and hospital operating suites to semiconductor fabrication facilities—demonstrating exceptional adaptability.

•  Superior Air Quality & Health Benefits

  • Advanced Filtration: Integrated multi-stage filtration effectively removes dust, pollen, bacteria, and viruses (with HEPA/ULPA filters), significantly improving Indoor Air Quality (IAQ).

  • Controlled Fresh Air Ventilation: Precisely manages and introduces a required proportion of outdoor fresh air to dilute indoor CO₂ and pollutants. This promotes occupant health, comfort, and compliance with green building standards.

•  Significant Energy Efficiency Potential

  • Energy Recovery: Can be integrated with heat recovery devices (e.g., energy wheels, plate heat exchangers) that use exhaust air energy to pre-condition incoming fresh air, dramatically reducing heating and cooling loads.

  • Variable Frequency Drive (VFD) Control: Fans are commonly equipped with VFDs, allowing speed adjustment based on real-time demand. This avoids energy waste and ensures efficient operation at part-load conditions.

•  Ease of Maintenance & High Reliability

  • Centralized Maintenance: All core components (filters, coils, fans, humidifiers) are housed in an equipment room, making them easy to inspect, service, and repair, thereby reducing long-term operational costs.

  • System Robustness: Professional engineering and manufacturing ensure high reliability and long service life, even under demanding 24/7 continuous operation in industrial settings.

Cleanroom HVAC Applications

Technical Specifications

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.
