3.2. Pressure control: control the pressure of the chamber and the transition chamber at a certain set point.
A) The user can arbitrarily set the working pressure interval between +12.5 and -12.5 mbar, and PLC will automatically regulate the pressure of the box within the set range. The default operating pressure range is -1 to +3 mbar.
B) When the box pressure is greater than 12 mbar, PLC automatically opens the safety valve to relieve pressure and protect gloves, equipment and materials in the box.
C) Use foot switch to fine tune the box pressure.
3.3. Foot pedal: can control the pressure of glove box, easy to operate.
4. Circulation system (including purification and regeneration system)
4.1. Germany BASF, United States UOP purification materials, Germany Baode valve. The host system is integrated with modular design. The automatic electronic control gas path solenoid valve set, PLC control, circuit, circulating pump, purification house and display are integrated with an independent purifier, forming a compact and simple system.
4.2. Control: water and oxygen are controlled in less than 1PPm
4.3 Adjustment device: through PLC touch type adjustment (heating, evacuation, purification, regeneration) the whole process except 2.5 hours ventilation without human monitoring.
