4. Equipped with an independent temperature limit alarm system, it automatically interrupts when the temperature limit is exceeded, ensuring the safe operation of the experiment without any accidents;

5. The large observation window is equipped with lighting fixtures to keep the inside of the box bright, and three layers of vacuum glass are used to clearly observe the condition inside the box at all times;

6. The outer shell of the box is made of SECC steel plate sprayed with plastic, processed and formed by CNC machine tools, with a beautiful and novel shape and a non reactive handle, making it easy to operate.

2、 Freezing and air circulation system:

1. The refrigeration unit adopts the original French "Taikang" fully enclosed compressor;

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

3. Adopting a multi wing air circulation system to avoid any dead corners and ensure even temperature distribution within the testing area;

4. Heating, cooling, and system independence can improve efficiency, reduce testing costs, extend lifespan, and decrease failure rates;

5. The design of wind path circulation for air outlet and return ensures that the wind pressure and speed meet the testing standards, and can quickly stabilize the temperature at the moment of opening the door.
