large walk-in high and low temperature laboratory

large walk-in high and low temperature laboratory


1, large environmental laboratory can provide large parts, semi-finished products, finished products for temperature leakage environmental testing, which is mainly composed of control panel, switch board, insulation board, fan, heater, feeder, refrigerator, the main specifications are divided into six standard indoor sizes and 28 different conditions test specifications.

2, the use of library board unit combination, the content product can be arbitrarily enlarged, easy to disassemble and assemble, can be designed according to the size of customer needs and cooperate with the migration of customer factory expansion.

3, the material of the library plate is made of stainless steel and beautifying steel paint material, the structure is strong, waterproof and beautiful.

4, the use of multi-wing centrifugal air supply mode of horizontal diffusion vertical heat exchange circulation system, to avoid any dead Angle, so that the indoor temperature distribution is uniform.

5, programmable controller adopts OYO touch screen controller, simple operation, easy program editing, suitable for temperature variation test conditions, can be connected with the computer through the RS-232 interface, users can design programs on the computer screen, collect test data and record call program execution and other functions.

6. When abnormal conditions occur, the controller disaster screen automatically displays the fault status in real time, cuts off the power switch, and provides troubleshooting methods.

7, the refrigeration system adopts imported compressors from Europe and the United States, and uses environmental cooling coal. The refrigeration system adopts binary low-temperature loop system design, and uses different compressors to work with different temperature zones to increase the service life of the equipment.
