AHU Dezenno.MAX DeAir: The Ultimate Temperature & Humidity Control Solution for Modern Data Centers

AHU for Data Centers: Ensuring Performance and Safety with Dezenno.MAX Technology

In the digital age, data centers play a vital role, storing and processing petabytes of data, supporting all activities from business, communication to essential online services. However, the continuous operation of thousands of servers and IT equipment generates a large amount of heat, along with strict environmental operating requirements, posing a significant challenge in temperature and humidity control. These environmental factors directly affect the operating performance and lifespan of IT equipment.

To address this challenge, AHU (Air Handling Unit) is affirmed as the heart of the environmental control system in data centers. DeAir, as a specialist in air treatment in Vietnam, has developed the AHU Dezenno.MAX product line, specifically designed for applications requiring high precision. DeAir's AHU Dezenno.MAX is the optimal solution to maintain an ideal environment for modern data centers.

Why do Data Centers need specialized AHUs?

Maintaining a stable and optimal environment is extremely important for data centers. Specialized AHUs meet these requirements through key functions:

• Precise temperature control: IT equipment in data centers generates a large amount of heat. To avoid overheating, reduced performance, and equipment damage, maintaining a stable temperature is paramount. AHU ensures efficient air circulation and cooling, keeping the temperature within the permissible range (ideally 18-27°C according to ASHRAE), protecting sensitive electronic components.
• Optimal humidity control: Humidity is a critical factor but often underestimated in data centers.
  • Too high humidity can cause condensation, leading to rust, short circuits, and damage to electronic components.
  • Too low humidity can cause electrostatic discharge (ESD), posing a risk of electrical discharge that can damage sensitive devices like circuit boards and hard drives, leading to data loss and operational downtime. AHU must maintain an ideal humidity range (optimally 40-60% according to ASHRAE) according to international standards for data centers to prevent these risks.
• Air quality: Specialized AHUs also have the ability to filter dust and microscopic particles to protect equipment, prevent clogging, and reduce cooling efficiency. At the same time, they help prevent external contamination, ensuring clean air for the operating space.
• Energy saving: Data centers consume a very large amount of energy, accounting for 30-50% of total energy costs. An efficient AHU system will significantly reduce operating costs, contributing to the overall economic efficiency of the data center.

AHU Dezenno.MAX DeAir: Optimal Solution for Data Centers

DeAir's AHU Dezenno.MAX is designed to exceed the stringent requirements of data centers, delivering high performance and reliability:

• Specialized design for data centers:
  • High and flexible capacity: The AHU Dezenno.MAX product line is designed to meet various data center scales, with airflow ranging from 1,000 to 51,000 CMH and potentially up to 100,000 CMH.
  • High reliability: Ensures stable 24/7 operation, continuous high load capacity, minimizing disruption risks.
  • Premium materials and robust construction: Uses high-quality, corrosion-resistant materials, ensuring durability and long lifespan for the equipment. AHU Dezenno.MAX features a sturdy frame made of high-strength extruded aluminum and a thermal break profile. The casing is constructed from high-strength pentapost extruded aluminum sections and internal bars, combined with dual-module insulation material (25 or 50mm Polyurethane), which helps minimize heat loss and enhance operational efficiency.
• Precise temperature and humidity control technology:
  • High-quality components: Uses components such as high-efficiency centrifugal fans (with optional AMCA certified fans - Air Movement and Control Association International), heat exchangers (coils made from corrugated aluminum fins and seamless copper tubes, with optional corrosion resistance and optimized for better heat exchange performance), and advanced air filters (with optional UL certified filters - Underwriters Laboratories). The drain pan efficiently collects condensate. You can learn more about fan systems in AHU through DeAir's cooperation with ZIEHL-ABEGG.
  • Smart control system: Integrates a smart control system and precise sensors, allowing remote monitoring and control with online devices. The system can connect to a BMS (Building Management System) via standard protocols.
  • Ability to integrate specialized modules: AHU Dezenno.MAX can integrate additional specialized modules for more precise humidity control, such as DeAir.HM steam humidifiers or can be combined with Dezenno rotor dehumidifiers. For controlling humidity down to very low dew points, Dezenno rotor dehumidifiers are an optimal solution. Additionally, electric heaters and heat recovery wheels can be integrated.
• Superior energy efficiency:
  • Advanced technology: AHU Dezenno.MAX applies advanced technologies such as VFD (Variable Frequency Drive) to flexibly adjust fan speed, optimizing performance and saving energy. Heat Recovery technology is also an option that significantly reduces the cost of heating or cooling outside air.
  • Design minimizing heat loss: The thermal break configuration and airtight casing in accordance with EN 1886:2007 standard of AHU Dezenno.MAX are designed to minimize energy consumption and condensation.
  • Heat Pump application: DeAir is also an expert in energy-saving Heat Pump (heat pump) solutions. This technology can be applied to optimize cooling and dehumidification efficiency in related solutions (e.g., DeAir.RE Heat Pump dehumidifiers), utilizing heat released during condensation to heat the air after dehumidification, helping to save electricity consumption and dehumidify faster and more efficiently.
