Application of walk-in large alternating humidity and heat test room:

The walk-in high and low temperature alternating humidity test chamber is used for heat and cold resistance testing of defense industry, aerospace industry, automation components, automotive parts, electronic and electrical components, plastics, chemical industry, pharmaceutical industry and related products.

Performance: The performance measured after being stable for 2 hours without test load or scaffolding. In addition, the temperature rise and fall time refers to the performance of air-cooled systems at room temperature+25 ℃ under no-load conditions

Intelligent operating system for alternating humidity and heat test room: (control system)

The controller operation interface is available in both Chinese and English, and the real-time operation curve chart can be displayed on the screen.

It has a capacity of 120 sets of programs, 12000 segments, and 999 loop steps, with a maximum time setting of 99 hours and 59 minutes per segment.

After inputting the data and experimental conditions, the controller has a screen lock function to avoid manual touch and shutdown.

It has the function of automatic calculation, which can immediately correct the temperature and humidity change conditions, making temperature and humidity control more accurate and stable.

Freezing and air circulation system.

The refrigeration unit adopts the original French 'Taikang' fully enclosed compressor.

The refrigeration system adopts a unit or binary low-temperature circuit system design.

Adopting a multi wing air supply fan for strong air circulation, avoiding any dead corners, can make the temperature and humidity distribution in the testing area uniform.
