3. Characteristics of high and low temperature (explosion-proof) test box products

(1) The use of internationally imported compressors and internationally renowned refrigeration components ensures the stable performance of the refrigeration system.

(2) The box adopts a stainless steel inner liner, and the surface of the high-quality cold-rolled plate is treated with phosphating and spray coating, giving it a generous and beautiful appearance.

(3) Adopting imported high-quality temperature control instruments or touch screen+PLC control methods.

(4) Multiple safety protections: refrigerant high-pressure protection, compressor overload protection, overcurrent protection, overtemperature protection, and leakage protection.

(5) Explosion proof pressure relief port: An explosion-proof pressure relief port is installed at the top of the working room. When the pressure inside the box increases sharply due to abnormal working conditions, the pressure relief port is used

The mouth automatically opens to relieve the destructive pressure inside the box.

(6) Mechanical door lock ensures that the box door does not automatically open due to the rise inside the box

(7) Protective gas: (optional) Fill the box with inert gas to dilute the oxygen concentration of the gas inside the box.

(8) Fire extinguishing system: (optional) equipped with gas fire extinguishing device outside the box. When the pressure relief port is opened or the temperature inside the box exceeds the protection set value, the fire extinguishing device will

Spray fire extinguishing gas into the box.
