AHU Dezenno.MAX: A Comprehensive Air Handling Solution for Modern Airports

An airport is not just a key transportation hub but a "mini-city" that never sleeps. With millions of passengers annually, 24/7 continuous operation, and complex functional areas, ensuring a fresh, safe, and comfortable air environment is a vital factor that directly impacts passenger experience and operator reputation, as assessed by prestigious organizations like the Airports Council International (ACI).

The heart of this intricate HVAC (Heating, Ventilation, and Air Conditioning) system is the Air Handling Unit (AHU). Deeply understanding these challenges, DeAir introduces the AHU Dezenno.MAX product line – a tailor-made solution with advanced technology that meets the most stringent international standards specifically for the unique airport environment.

Specific Requirements for Airport AHU Systems

Airport AHU systems face some of the most unique and demanding requirements, far exceeding those of typical commercial applications:

• Massive Cooling Load and Airflow: Lobbies, check-in areas, and corridors are vast spaces requiring high-capacity AHUs to ensure air is circulated and cooled evenly.
• Strict Indoor Air Quality (IAQ) Control: The huge flow of people from around the world brings risks of bacteria and viruses. AHUs must be able to filter fine dust (PM2.5, PM1.0), allergens, and effectively control CO2 levels.
• Continuous 24/7/365 Operation: The equipment must have absolute reliability, durable materials, and a design that allows for easy maintenance without disrupting operations.
• Energy Cost Optimization: The HVAC system accounts for 40-60% of an airport's total electricity costs. Therefore, an energy-saving system is a critical economic consideration.
• Precise Humidity Control: Especially in Vietnam's hot and humid climate, AHUs need to effectively dehumidify to prevent condensation on large glass walls, protect interiors and electronic equipment, and provide comfort for passengers.
• Low Noise Levels: Ensuring quiet and luxury in key areas such as business lounges and rest areas.
• Safety and Durability: Materials must meet fire safety standards and be corrosion-resistant, especially at coastal airports exposed to salt spray.

Dezenno.MAX DeAir - The Comprehensive Solution for Airport HVAC Systems

The Dezenno.MAX AHU is designed to thoroughly address the above challenges, providing a comprehensive and efficient air handling solution.

Flexible Modular Design, Meeting Any Scale

Each area in an airport has different requirements. Dezenno.MAX's modular block design allows for flexible configuration: from airflow and cooling/heating capacity to filtration levels and functions like heat recovery and dehumidification. This ensures each AHU is optimized for its specific location, from bustling check-in halls to quiet air traffic control towers, optimizing both performance and investment costs.

Superior Energy Efficiency with Advanced Technology

DeAir prioritizes energy savings in every aspect of the Dezenno.MAX design:

• High-Efficiency EC Fans: DeAir integrates EC (Electronically Commutated) Fans from world-leading brands (G7/EU) such as ZIEHL-ABEGG, EBM-Pabst, Comefri... These fans not only save over 30% more energy than traditional AC fans but also allow for stepless speed control, quiet operation, and a long lifespan.
• Heat Recovery Wheel (HRW): The optional integration of a Heat Recovery Wheel can recover 70-80% of the energy from exhaust air, significantly reducing the load on the central Chiller system.
• Anti-Thermal-Loss Panel Casing: The AHU casing is made from high-density (40-45 kg/m³) Polyurethane (PU) panels, 50mm thick, with a thermal break aluminum frame design, which almost completely eliminates thermal bridging and prevents energy loss.

Multi-Stage Filtration System, Ensuring International Standard Clean Air

To ensure the highest level of Indoor Air Quality (IAQ), the Dezenno.MAX AHU can integrate a multi-stage filtration system that complies with the ASHRAE 62.1 standard:

• Stage 1: G4 pre-filter removes large dust, hair, and insects.
• Stage 2: F7/F8 fine filter removes fine dust and pollen.
• Stage 3: HEPA H13/H14 filter (optional) for areas requiring sterile conditions, such as a clean room, capable of capturing 99.99% of ultra-fine particles and bacteria.
• Stage 4: Activated carbon filter (optional) to remove odors and volatile organic compounds (VOCs).

Precise Humidity Control - Integrated DeAir Solution

The Dezenno.MAX AHU uses a cooling coil with a large surface area and appropriate air velocity to optimize moisture removal from the air. For areas with extremely low humidity requirements or harsh operating conditions, DeAir can integrate specialized industrial rotor dehumidifiers directly into the AHU system, providing precise humidity control down to 1%.

Durable, Reliable & Corrosion-Resistant Operation

Designed for an operational lifespan of over 20 years, the Dezenno.MAX features a robust construction with a high-grade aluminum profile frame and a casing of galvanized steel or Stainless Steel 304/316. Especially for coastal airport projects (Da Nang, Cam Ranh, Phu Quoc, Van Don), DeAir offers an optional Epoxy coating for the entire casing and metal parts, creating a perfect protective layer against salt spray corrosion.

Smart Control System Integration (BMS)

The Dezenno.MAX AHU is ready to connect with the Building Management System (BMS) through common protocols like Modbus or BACnet. This allows the central control center to monitor and command the entire AHU system remotely, track operating parameters (temperature, humidity, CO2, pressure...), optimize operating schedules, and receive early fault alerts, ensuring the system always operates stably and efficiently.
