[Case Study] Achieving Ultra-Low 5% RH Humidity Control for a Lab with Dezenno Rotor Dehumidifier

1. The Challenge: Strict Technical Requirements for a Laboratory in Nha Trang

In May 2023, DeAir faced one of its most complex technical challenges: designing and installing an air treatment system for a laboratory (LAB) in Nha Trang. The client's request was not merely for dehumidification but for the creation of an environment controlled with extreme precision.

The Problem Statement:

The environment inside the lab had to be consistently maintained at a temperature of 40°C and an ultra-low relative humidity (RH) of just 5%.

• Analyzing the Challenge: A 5% RH level is an extremely demanding threshold, far beyond the capabilities of all conventional condensation-based dehumidification technologies. This environment is mandatory for research activities involving sensitive semiconductor materials, ultra-sensitive electronic components, or chemical reactions where the presence of water vapor could completely skew the results. This problem demanded a superior technological solution.

2. DeAir's Breakthrough Solution: Dezenno Rotor Dehumidifier Technology

Faced with this high-tech requirement, DeAir's engineering team determined that only desiccant rotor technology could meet the demand. [cite_start]We recommended and implemented the Dezenno rotor dehumidifier – a "Made in Vietnam" product manufactured to European standards[cite: 910].

Why was Dezenno the only choice?

• Superior Technology: Dezenno utilizes a rotor wheel containing silica gel particles with millions of micro-capillaries, capable of adsorbing water vapor at a molecular level. This allows for lowering the air's dew point to extremely low levels, easily achieving 5% RH or even lower.

• Precise Control: The system integrates an intelligent PLC controller, allowing for simultaneous and precise monitoring and adjustment of both temperature and humidity, ensuring the lab environment remains stable 24/7[cite: 919].

• Specialized Design: The machine's casing is constructed with a double-skinned, insulated panel, ensuring optimal performance and durability under the most demanding operating conditions[cite: 926].

The installation was meticulously carried out by DeAir's engineers, adhering to strict technical standards to ensure the system operated optimally from the very first run.

3. The Result: Stable Operation, 100% Compliance with Technical Requirements

After handover, the Dezenno rotor humidity control system operated flawlessly, earning the complete satisfaction of the client.

The Achieved Results:

• The system consistently and accurately maintains the lab environment at 40°C and 5% RH.
• It creates the ideal research conditions, enabling the client's experiments and testing processes to achieve the highest degree of accuracy.
• It protects valuable electronic equipment and sensitive materials worth billions from the risk of moisture damage.
• It once again affirms DeAir's capability in providing the most specialized and complex air treatment solutions.

4. Dezenno Rotor Dehumidifier: When Low Humidity is Mission-Critical
