Humidification and Dehumidification System

Our test chambers provide controlled humidity from 20% to 95% relative humidity (depending on the chamber model) to evaluate the effects of humidity on products. This testing helps evaluate the stability, lifespan, and quality of products in environments where humidity is critical.

High-performance materials and structures

Inner box material: Made of SUS304# stainless steel plate, cut by precision laser cutting equipment and bent by CNC folding machine, then fully welded by argon arc welding, and polished

Outer box material: cold-rolled steel plate, cut by precision laser cutting equipment and bent by CNC folding machine, then welded by argon arc welding, polished and made; the surface of the steel plate is pickled and rust-removed as a whole, and then the surface is treated with high-temperature baking paint. Compared with the usual surface spraying treatment, the appearance is more beautiful and generous, and its anti-corrosion and anti-rust performance is enhanced.

In order to ensure uniform temperature and humidity in the test chamber, we use air circulation devices to optimize the temperature and humidity distribution.

Using external humidification, the compressor starts dehumidification, and P.I.D controls the humidification amount to achieve the required humidity.

Zhongzhi environmental humidity chamber technical advantages

Stepless Regulation-Energy-Saving Cooling Control Technology

Zhongzhi Instrument Testing Co., Ltd.'s cooling control technology can steplessly adjust the cooling output, and cooperate with independent cold-end and hot-end PID continuous adjustment to avoid energy waste caused by the hedging of cooling and heating capacity; thereby reducing actual energy consumption and saving more than 40% energy compared to conventional cold and heat balance methods.

Anti-Temperature Drift-Output Control

The output control method adopted by Zhongzhi detects the continuous changes in output at medium and high temperatures, and intelligently determines whether the compressor needs to be turned on, as well as the cooling output time (to avoid the temperature fluctuations in the working room caused by suddenly turning on the compressor). This not only effectively saves energy, but also avoids the temperature drift problem caused by heating of the test piece.

Shock and Noise Reduction Refrigeration System

Zhongzhi compressor has its own shockproof design, and the refrigeration system adopts an integrated design to reduce local vibration impact, effectively avoiding leakage at the copper pipe welding points or valve body interfaces due to uneven force and long-term operation in a vibrating environment, thereby ensuring good cooling performance.

Technical Insights & Knowledge for Environmental Humidity Chambers

Choosing the right environmental humidity chamber can be a complex task—especially when precision, reliability, and long-term performance are critical to your industry. This guide offers practical insights and expert knowledge to help you avoid costly mistakes and ensure the success of your testing operations.

What Is an Environmental Humidity Chamber?

An environmental humidity chamber is a test device used to simulate humidity conditions. It can test the performance changes of materials or products under controlled humidity environment conditions. It is commonly used in industries such as electronic components, pharmaceutical packaging, and textile materials.

Common Challenges in Humidity Testing Applications

When using environmental humidity chamber, the following common challenges are worth paying attention to:

1. Humidity Fluctuation Leads to Unstable Test Data

Under certain test conditions, humidity fluctuation will affect the consistency of data, especially in the test of humidity-sensitive materials, maintaining a stable relative humidity (RH) is particularly critical.

2. The Control System Responds Slowly and It Is Difficult to Quickly Reach the Target Humidity

The RH control system of some equipment has a long response time and it is difficult to reach the set humidity value in time. This not only prolongs the test preparation time, but also disrupts the overall test rhythm.

3. Water Source Problems When the Equipment Is Running for a Long Time

The humidification system has certain requirements for water quality. If untreated tap water is used for a long time, water supply issues such as scaling of the humidification pipeline and contamination of the sensor are prone to occur. In order to ensure the long-term stable operation of the system, it is recommended to equip it with a pure water system and a water quality filtration device.

4. The Balance Between Equipment Footprint and Space Efficiency

In laboratory and production environments, space resources are usually tight. Therefore, how to strike a balance between equipment footprint and space efficiency within a limited space and achieve space-saving design has become an important consideration when selecting equipment.

Key Technical Parameters to Consider

When choosing an environmental humidity chamber, you can focus on the following key technical parameters:

1. Humidity Range and Rh Accuracy

Whether the equipment can cover the humidity range of 20%RH to 98%RH and the control accuracy reaches ±2%RH is the key indicator to ensure the accuracy of the test results.

2. Humidity Rise and Fall Rate

Different test requirements have different requirements for the humidity change rate. Rapid test scenarios focus on higher humidity rise and fall rates, while stability tests emphasize the stable maintenance of humidity to ensure the stability of the test environment.

3. Humidity Control Method

Common humidity control technologies include ultrasonic humidification, steam humidification and dehumidification system. Different humidity control methods are suitable for different test environments and budget requirements.

4. Controller Type and Remote Monitoring Function

Modern equipment mostly uses touch screens and PLC controllers to achieve intuitive and convenient localized operation. Some models also support remote monitoring functions to further improve the convenience of operation and real-time monitoring capabilities during the test process.

Standards and Compliance Requirements of Key Industries

Environmental humidity chamber plays an important role in many industries, meeting the testing standards and compliance requirements of various industries:

1. Electronic and Electrical Industry

Used for moisture resistance testing and PCB life testing to verify the performance stability of electronic components in a hot and humid environment.

2. Pharmaceutical Industry

Perform stability testing in accordance with the ICH Q1A guidelines to ensure that the quality of drugs remains stable under different humidity conditions.

3. Materials and Packaging Industry

Evaluate its moisture resistance during long-term storage and transportation by simulating the humidity environment of the package.

4. Food Industry

Detect the integrity and moisture absorption characteristics of the package to ensure food safety.

Professional Advice: Don’t Just Look at the Technical Table When Selecting a Model

When purchasing an environmental humidity chamber, don’t just look at the surface parameters. Invisible parameters such as control system brand, service response speed and long-term data consistency are also key to affecting the reliability of the RH chamber. Ignoring these factors can easily lead to high after-sales support costs and testing risks.
