The "cooling" and "raising" of the high and low temperature boxes must be carried out by the refrigeration system. The selection of the refrigeration compressor determines the stability of the refrigeration system, which in turn determines the stability of the characteristics of the high and low temperature boxes. Generally, the high and low temperature boxes are air-cooled stand-alone. Air-cooled cascade reduction refrigeration method. To put it bluntly, the air-cooled stand-alone version is a refrigeration compressor, and the cascade reduction is a combination of two refrigeration compressors. Let me tell you about the structure of the high and low temperature box What are the characteristics?

Structural features of high and low temperature box:

1. The box body of the high and low temperature box is processed and formed by CNC lathe, with a unique shape and design, and a door handle without reaction force is selected, which is easy to operate.

2. The inner box adopts imported stainless steel plate (SUS304) mirror stainless steel, and the outer packaging adopts (SUS304) stainless steel wire drawing plate or cold-rolled plate electrostatic spraying, which improves the appearance and cleanliness level.

3. Equipped with a large and medium-sized observation window with lighting fixtures to maintain the light in the box, and the use of embedded tempered laminated glass with a heater to clearly observe the situation in the box anytime, anywhere.

4. The left side of the box is equipped with a detection hole with a diameter of 50mm, which can be used for external detection of power plugs or power cords.

5. The thermal insulation material is made of glass wool board with high density, and the thickness is 80100mm. Two layers of high-tensile sealing tape with high and low temperature resistance test are used between the door and the box to ensure the tightness of the detection area.

6. Equipped with a separate temperature limit alarm device, exceeding the limit temperature and automatic termination of operation, to ensure that the safety of the test is carried out without accidents.
