1. The product is beautiful in appearance, reasonable in structure, advanced in technology and exquisite in material selection, with simple and convenient operation performance and reliable equipment performance. The equipment is divided into three parts: high temperature box, low temperature box and test box. It adopts the unique heat cut-off structure and the effect of heat storage and cold storage. During the test, the object to be tested is completely static. The cold and hot temperatures are introduced into the test area by the way of cold and hot air path switching to achieve the purpose of cold and hot shock test

2. Adopt the most advanced measuring device, the controller adopts large-scale color LCD man-machine touch dialogue LCD man-machine interface controller, which is easy to operate, easy to learn, stable and reliable, and displays complete system operation status, execution and setting program curve in Chinese and English. 96 test specifications are set independently, the impact time is 999 hours and 59 minutes, and the cycle time is 1-999 times, which can be set. It can realize the automatic operation of the refrigerator, realize the automation to the greatest extent, reduce the workload of the operators, and automatically start and stop the operation at any time;

3. There is a test hole with a diameter of 50 mm on the left side of the box, which can be used for testing components of external power load wiring. It can independently set the functions of high temperature, low temperature and cold and hot shock. When performing the cold and hot shock conditions, it can select the functions of two groove or three groove and cold and hot shock for impact. It has the functions of high and low temperature testing machine.

4. It has full-automatic, high-precision system circuit, any movement of machine parts, full p.l.c locking treatment, all using p.i.d automatic calculation control, high temperature control accuracy, advanced scientific air circulation design, making indoor temperature uniform, avoiding any dead angle; complete safety protection device, avoiding any potential safety hazard, ensuring the long-term reliability of the equipment

5. The number of cycles and defrosting times can be set to automatically (manually) defrost. The air outlet is detected and controlled by the air return sensor. The switching time of the damper mechanism is 10 seconds, and the recovery time of the bell brand cold and hot shock temperature is 5 minutes. During operation, the status display and curve display. In case of abnormal conditions, the screen will automatically display the fault points and causes and provide troubleshooting methods. In case of unstable input power, it will be equipped with an emergency stop device.

6. The refrigeration system adopts the design of overlapping high-efficiency low-temperature circuit system. The refrigeration unit adopts the original compressor imported from Europe and America, and adopts the green environmental protection (HFC) refrigerant r507, R23. Super safe protection function: power overload protection, leakage protection, control circuit overload, short-circuit protection, compressor protection, grounding protection, over temperature protection, alarm sound prompt, etc 。
