WBE-BRS Walk-in constant temperature and humidity test chamber

The walk-in high-low temperature alternating test chamber is a test device that tests the performance of a sample by technical means, simulating it in a situation that is often encountered in the natural environment, and combining several times the harsh conditions of the natural environment. It is mainly used in defense industry, aerospace industry, auto parts, auto parts, electronic equipment, plastics, chemicals, pharmaceuticals and other related industries. It is suitable for testing products with large quantity and large volume. Whether it is heat-resistant or cold-resistant test, it can provide large-scale parts, semi-finished products and finished products for the industry.



1. It has a wide temperature and humidity control range to meet the various needs of users. With a unique balanced temperature and humidity control method, a safe and accurate temperature and humidity environment can be obtained. With stable and balanced heating and humidifying performance, it can control high temperature and high stability temperature and humidity.

2. Adopting Korean imported controllers;

3. The refrigeration circuit is automatically selected. The automatic control device has the function of automatically selecting the running refrigeration circuit with the set value of the temperature, and directly starts the refrigerator under the high temperature state and directly cools down.

4. The inner door is equipped with a large observation window to facilitate the observation of the test condition of the test article.

5, equipped with advanced safety protection devices --- leakage circuit breakers, over-temperature protectors, phase loss protectors, water shut-off protectors.
