2.1.4. Vacuum degree ≤ 1bar (both large and small right transition cabins require vacuuming with display)
3. Control system
3.1. Method: Including self-diagnosis, self-starting after power failure, with pressure control and self-adaptive functions. LCD display is used for automatic control, cycle control, password protection and vacuum chamber control. The unit control adopts Siemens PLC touch screen.
3.2. Pressure control: control the pressure of the tank and transition chamber at a certain set value.
a) The user can arbitrarily set the working pressure range between +12.5 and -12.5 mbar, and the PLC will automatically control the pressure of the box within the set range. The default value for the working pressure range is -1 to +3 mbar.
b) When the box pressure is greater than 12 mbar, the PLC automatically opens the safety valve to release the pressure to protect the gloves, equipment and materials in the box.
c) Use the foot switch to fine-tune the tank pressure.
3.3. Foot pedal: It can control the pressure of the glove box and facilitate operation.
4. Circulation system (including purification regeneration system)
4.1. German BASF, American UOP purification materials, German Baode valves. The host system integrates a modular design, fully automatic electronically controlled air circuit solenoid valve group, PLC control, circuit, circulation pump, purification chamber, and display are integrated into an independent purifier, forming a compact and simple system.
4.2. Control: water and oxygen are controlled at less than 1PPm
4.3. Adjustment device: through PLC touch adjustment (heating, evacuation, purification, regeneration) the whole process except 2.5 hours of ventilation without human monitoring.
4.4． Working gas: He.N2/ or Ar gas (gas cycle)

The water removal capacity is 2.2kg and the oxygen absorption capacity is 63L.
4.7． Purification valve: fully automatic electro-pneumatic valve.
4.8． Filter: A high-efficiency filter with a 0.3-micron pore size filter that meets HEPA standards.
4.9. Regeneration: It is used to re-use the purification system to activate it; regeneration requires a mixed gas of helium/H2, nitrogen/H2 or argon/H2, of which H2 accounts for 10%.
4.10. The regeneration gas enters the purification column through the advanced flow meter.
5. Display system
Germany SIEMENS, unit control adopts Siemens PLC touch screen. Chinese and English bilingual can be switched.
6. Water analyzer, (imported from abroad) Brand material: British MICHELL/ (determined according to the customer's use environment)
Non-domestic or domestic assembly, third-party data guarantee credibility.
1) Measuring range: 0-1000ppm
2) Accuracy: ±1%ppm
3) Display: The output of the analyzer is connected to the PLC, the detected value is displayed on the touch screen, and the alarm value can be set.
4) Control: The gas circulation system can be controlled according to the user's settings to achieve circulation reduction.
5) Environment: -10℃—50℃
7. Oxygen analyzer, (imported from abroad) Brand material: American AVCRAY (determined according to the customer's use environment)
Non-domestic or domestic assembly, third-party data guarantee credibility.
1) Measuring range can be set: 0-1000, ppm
2) Environment: -10°C - 50°C
3) Accuracy: ±1% ppm
4) Installation position: The oxygen sensor is installed on the box body. No matter whether the gas circulates or not, the oxygen sensor continuously detects the atmosphere in the box and displays the oxygen content in the glove box.
5) Sensor: Electrochemical material battery, which has the advantages of accurate zero point, small drift, and avoids easy corrosion of other battery materials; low replacement cost (only oxygen battery is replaced).

7) Control: The user can choose the automatic circulation function to maintain the oxygen content in the glove box within the specified range of the user.
8. Vacuum system
Increase the start and stop time control of the vacuum pump. The vacuum pump is an Edwards vacuum pump from England, model RV12, with a flow rate of 12m3/h and an ultimate vacuum of 2x10-3 mbar. The transition chamber can be evacuated separately and can be controlled independently at any time. (Imported from abroad)
9. Automatic cleaning of the cabinet
Automatic air control electroplating plate; automatic gas cleaning function in the box The user sets the cleaning time, and then touches the start button on the touch screen, the system will start cleaning the box, and it will automatically stop when the set time is reached.
10. Organic solvent adsorption system
In order to prevent the influence of organic solvents on the purification column, a solvent column is connected in series to the glove box system. The medium is mainly high-quality and efficient activated carbon and activated alumina to prevent the formation of hydrofluoric acid. The filling capacity of the organic solvent adsorption system is 7KG, and there are KF40 interfaces on the upper and lower sides of the column, which is convenient for refueling, and the user can refuel by himself.
