Walk-in Environmental Test Chamber

Sanwood walk-in environmental test chambers are engineered to meet modern industry demands for large-scale, high-precision environmental reliability testing. The walk-in configuration provides flexible, high-capacity testing space, enabling whole vehicle components, battery packs, communication cabinets, or high-volume products to undergo consistency and durability assessments under controlled, extreme conditions.

• •Offering non-standard customization ranging from several cubic meters to dozens of cubic meters.
• •Featuring a high-efficiency refrigeration system and advanced airflow design, it ensures rapid temperature changes (e.g., 3-10°C/min) and excellent temperature and humidity uniformity even in large spaces.
• •The inner chamber is constructed from SUS 304 stainless steel with a reinforced structure to ensure long-term stable operation.
• •Equipped with a wide array of test lead ports, viewing windows, and internal illumination to accommodate diverse testing configurations.

Walk-in test chambers are widely used in several industries such as aerospace and defense , automotive industry , large-scale electronics and telecommunications due to their versatility and wide range of testing capabilities .

• •Aerospace and Defense:It can effectively simulate extreme environmental conditions such as high pressure, high temperature, and high humidity, conduct rigorous reliability tests on spacecraft, satellites, and avionics equipment, and provide strong support for aircraft performance verification.
• •Automotive Industry:Walk-in test chambers are used to test the performance of automotive parts and complete vehicles under extreme temperature and humidity conditions, such as the temperature resistance, moisture resistance and long-term stability of components such as batteries, electronic control units, lamps, and vehicle systems .
• •Electronics and Telecommunications:Walk-in test chambers help evaluate the reliability and functionality of electronic equipment, telecommunications equipment, and electrical components by subjecting them to controlled temperature, humidity, and other conditions.

A walk-in test chamber is a device used to simulate different environmental conditions for testing. Its test standards usually involve the following aspects:

• •EN 60068-2-2, IEC 60068-2-1, etc., specify the test methods and standards for walk-in test chambers at different temperatures.
• •EN 60068-2-30, IEC 60068-2-30, etc., specify the test methods and standards for walk-in test chambers at different humidity levels.
• •IEC 60068-2-78, GB/T 2423.22, etc., specify the test methods and standards for walk-in test chambers under different pressures.
• •IEC 60068-2-6, GB/T 2423.8, etc., specify the test methods and standards for walk-in test chambers under different vibration conditions.
• •IEC 60068-2 series, GB/T 10589, etc., specify the test methods and standards for the adaptability of walk-in test chambers under different environmental conditions.

The control system of the Sanwood test chamber adopts the world's leading software and hardware system to ensure that the test chamber operates under preset conditions, provide accurate and reliable experimental data, and help users achieve precise control and data collection of various experimental conditions.

• •Controller: It adopts the controller imported from South Korea Sanwon and the self-developed control system, which can be equipped with Siemens control system and equipped with RS232, RS485 and Ethernet communication ports.
• •Programmable control: It supports setting experimental programs, such as heating, cooling, constant temperature time, etc., and can execute multiple program settings, and supports advance reservation startup function.
• •Multiple languages optional: English, Korean, Russian, Chinese and Japanese.
• •Remote monitoring: Using network remote technology to achieve remote control, the test chamber can be monitored at any time, and the current data can be viewed through the user's PC and mobile phone, which improves the convenience of testing.

The specific control system of the test chamber will vary depending on the model. Please read the "Sanwood Environmental Test Chamber Manual" carefully before use and comply with the safety operating procedures.

The refrigeration system of the test chamber is a complex and important system. The stability of the refrigeration system is crucial to the accuracy and reliability of the test results.

• •Sanwood Technology has developed a refrigerant hot gas defrosting technology, which effectively melts the frost on the evaporator by injecting high-temperature and high-pressure refrigerant steam into the heat exchanger in the test chamber. This not only ensures that the evaporator does not frost, but also greatly reduces the energy consumption of the equipment.
• •The refrigeration unit adopts an internationally renowned brand.
• •Optimize the layout of the refrigeration system, and adopt VRF (refrigerant flow control) technology based on the PID cold end output principle to achieve low-temperature energy-saving operation, which can reduce energy consumption by 30% under low-temperature conditions.
• •The refrigeration system adopts a modular design, with low failure rate, few welding points, high refrigeration efficiency, good reliability, simple maintenance, and low maintenance cost.
