1.7. The box is equipped with anti-reflection lighting energy-saving lamps, and the light is soft.

1.8. There are two layers of display boards in the box

1.9. There is a multi-hole power terminal board in the box (power supply: 220V±10% 50Hz±10%)

1.10. The cabinet can be set with 3 standard KF-40 ports.

1.11. Leakage rate: ≤0.01vol%/h.

1.12. Steel structure bracket, height 950 mm, mounted with swivel casters.

2. Transition cabin

2.1. Shape: Cylindrical (304 stainless steel), connected to the glove box, with shaft lock type large transition hatch, easy to operate.

2.2. Size: diameter 390mm, length 600mm large transition cabin, piston door, sliding tray in the transition cabin, polished, another small transition cabin in the box, specifications: diameter 150mm, length 300mm, manual valve control air extraction and air supply .

2.3. Tray: stainless steel 300mm×450mm, free to move and extend (large transition cabin configuration)

2.4. Vacuum degree ≤ 1bar (both large and small right transition cabins are required to be evacuated with display)

3. Control system

3.1. Mode: including self-diagnosis, self-starting characteristics 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 box and transition cabin at a certain set value.

3.3. Foot pedal: can control the pressure of the glove box, easy to operate.

4. Circulation system (including purification and regeneration system)

4.1. German BASF, American UOP purification material, German Baode valve. The host system integrates modular design, fully automatic electric control gas circuit solenoid valve group, PLC control, circuit, circulating pump, purification, display integrates an independent purifier to form a compact and simple system. (Add an alarm. Box body When the pressure exceeds ±10mbar, the water and oxygen exceed the range alarm. The alarm can be turned off manually)

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 does not require human monitoring except for 2.5 hours of ventilation.

4.4. Working gas: He.N2/or Ar gas (gas circulation)

4.5. Circulation fan: 0-100m³ high-speed variable frequency fan, microprocessor controlled, stainless steel device that has been pressure tested.

4.6. Purification column: single purification column, imported purification material.

4.7. Purge valve: fully automatic electric valve.

4.8. Filter: High-efficiency filter with HEPA-compliant 0.3 micron pore size filter.

4.9. Regeneration: It is used to re-use and activate the purification system; regeneration requires a mixture of helium/H2, nitrogen/H2 or argon/H2, of which H2 accounts for 10%.

5. Display system

Germany SIEMENS, the unit control adopts Siemens PLC touch screen. Chinese and English bilingual can be switched.

6. PLC oxygen analyzer

Range: 0-1000PPm

Error: ±1%PPm

Environment: -10℃-50℃

7. PLC water analyzer

Range: 0-500PPm

Error: ±1% PPm

Environment: -10℃-50℃

8. Water probe protection device.

The water probe can be used for long-term detection and segmented detection.

9. The box is automatically cleaned.

Automatic box cleaning function. The gas environment of different nature is replaced and the water and oxygen are quickly cleaned automatically by the misoperation. The automatic clearing valve of the box body to the integration of the box body pipe should be firmly connected with KF25 steel wire plastic pipe, and the external KF25 pagoda joint should be used.

10. Organic solvent adsorption system

   304 stainless steel, diameter 220mm*470mm, with vacuum, filled with 7kg high-quality activated carbon. It can be operated independently and is easy to replace.
