Overview

It uses liquid nitrogen as a cooling medium to lower the temperature of the low-temperature chamber to -196 ℃, and the temperature is controllable. The inner wall of the liquid nitrogen cryogenic low-temperature box is made of stainless steel, and the temperature is controlled by intelligent instruments. The system structure is simple, the component layout is compact, and the operation is intuitive and simple.

Technical parameters of liquid nitrogen cryogenic chamber:
Effective dimensions inside the box: 600mm × 500 × 500 mm (can be customized as needed);
Working temperature: RT+10 ℃~-196 ℃ can be set arbitrarily;
*Large cooling rate: 1-30 ℃/min;
Temperature control accuracy: heating, cooling, constant temperature ± 0.5 ℃;
Temperature field uniformity: ± 2 ℃;
Opening direction of the box door: upward lifting (lid opening);
Box door sealing: A special low-temperature resistant material sealing device ensures that the box door can open freely.
Liquid nitrogen system: including liquid nitrogen tank, insulated pipe, control valve, nozzle, distributor. Liquid nitrogen is injected through multi-point injection to ensure the uniformity of temperature inside the box;
Power supply: 380V, 50Hz, 10A;
Equipment dimensions: 1350mm × 900mm × 1050mm.

Liquid nitrogen cryogenic box control system:
The control adopts a touch screen+PLC control method, with touch screen or computer as the upper computer and PLC as the lower computer, making operation and input curves more convenient. It can also monitor temperature changes inside the box in real time, observe the operation of the curve, and compare the set curve with the running curve.

Thermal insulation effect of liquid nitrogen low-temperature box
Multi layer composite structure of temperature resistant, flame-retardant, and ultra-low temperature insulation materials; The multi-layer insulation material with special treatment has good thermal insulation performance.
The box adopts reinforced treatment, which can reliably bear the weight of the workpiece. The special design ensures that the wind direction and airflow inside the box are not blocked, ensuring the temperature inside the box.
Internal wind direction circulation system - using ultra-low temperature fans, motors, and airflow distribution devices to ensure the uniformity of temperature inside the box.
