2. Transition cabinet

2.1 Shape: cylindrical (304 stainless steel), connected with the glove box, the use of shaft-locked large transition cabinet, easy to operate.

2.2 Dimensions: diameter 360mm, 600mm long large transition chamber, piston door, transition cabinet has a sliding tray, polished, the box is set up in another small transition cabinet, specifications: diameter 150mm, 300mm long, manual valve control pumping and make-up air.

2.3 Tray: stainless steel 260mm × 580mm, free to move the extension (used for large transition cabinet)

2.4 Vacuum degree ≤ 1bar (large and small right over the cabin are required to vacuum with display)

3. Control system

3.1 Methods: including self-diagnosis, power failure and self-starting characteristics, with pressure control and self-adaptive function. Automatic control, cycle control, password protection, vacuum chamber control using LCD display. Unit control adopts Siemens PLC touch screen.

3.2 Pressure control: Control the pressure of the box and transition chamber at a certain set value.

a) The user can set any working pressure interval between +12.5 and -12.5 millibars, and the PLC will automatically regulate the pressure of the box in the set range. The default value of the working pressure interval is -1 to +3 mbar.

b) When the box pressure is greater than 12 mbar, the PLC will automatically open the safety valve to relieve pressure and protect gloves, equipment and materials inside the box.

c) Use the foot switch to fine tune the box pressure.

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 Germany BASF, the United States UOP purification materials, Germany Baode valve. Host system integrated modular design, fully automatic electronically controlled gas solenoid valve group, PLC control, circuits, circulating pumps, purification of the residence, the display is integrated into an independent purifier, constituting a compact, simple system.

4.2 Control: water control in less than 1PPm

4.3 Adjustment device: through the PLC touch regulation (heating, evacuation, purification, regeneration) in addition to the whole process of 2.5 hours of ventilation without human monitoring.

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

4.5 Circulation fan: 0-100m³ high-speed frequency conversion fan, microprocessor control, after the pressure test stainless steel device.

4.6 Purification column: single purification column, imported purification material, American UOP high efficient water absorbing material 10kg, very high degree of life span, to ensure that the user in the use of the process of the product purification ability of long lasting. The water removal capacity is 4㎏.

4.7 Purification valve: full-automatic electro-pneumatic valve.

4.8 Filter: It adopts the high efficiency filter with 0.3 micron aperture in accordance with HEPA standard.

4.9 Regeneration: used to purify the system again, so that the activation; regeneration needs helium / H2, nitrogen / H2 or argon / H2 gas mixture, of which H2 accounted for 10%.

Regenerated gas into the flow meter and then into the purification column.

5. Display system.

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

6. Vacuum system

Increase the vacuum pump start-stop time control. The vacuum pump adopts British Edwards vacuum pump, model RV12, flow rate 12m3/h, ultimate vacuum 2x10-3 mbar. It can vacuum the transition chamber separately and realize separate control at any time. (Imported from abroad)

7. Box automatically cleaned

Automatic gas control plating plate; box gas automatic cleaning function users set the cleaning time, and then touch the start button on the touch screen, the system will begin to clean the box, to the set time is automatically stop. Automatic box cleaning function. Different nature of the gas environment replacement and misoperation into the water, oxygen fast box body automatic cleaning. The automatic cleaning valve to the box body piping integration using KF25 steel wire with steel tubes firmly connected to the external interface KF25 Pagoda connector.

8. Organic solvent adsorption system

In order to prevent the impact of organic solvents on the purification column, a solvent column in series to the glove box system, the medium is mainly high-quality high-efficiency activated carbon and activated alumina to prevent the formation of hydrofluoric acid. Organic solvent adsorption system filling capacity of 7KG, in the column of the upper and lower KF40 interface, easy to change the material, the user can change the material, in order to prevent the formation of hydrofluoric acid, solvent column tank half of the activated alumina.
