IIIBD/GDJW-225 Tianjin High and Low Temperature Alternating Test MachineBox material:
1. The shell is processed and formed using high-quality A3 steel plate CNC machine tools, and the surface of the shell is treated with anti-static spray coating, making it more smooth and beautiful;
2. The inner liner is made of high-quality SUS304 mirror stainless steel plate;
3. High density glass fiber cotton is selected as the insulation material, with a thickness of 100mm for the insulation layer;
4. The temperature circulation system adopts a specially designed low-noise long axis fan motor with stainless steel multi blade impellers that are resistant to high and low temperatures, to achieve strong convection and vertical diffusion circulation;
5. A double-layer high-temperature resistant high tensile sealing strip is used between the door and the box to ensure the sealing of the testing area;
6. Adopting non reactive door handles makes operation easier;
7. The bottom of the machine adopts high-quality fixed PU movable wheels;
8. The observation window adopts multi-layer insulated tempered glass, and the inner side is coated with laminated conductive film for heating and defrosting (clearly observe the test process);
9. The test hole (on the left side of the machine) can be used for external testing power or signal lines (the aperture or number of holes needs to be increased and indicated);
