Glove Box Installation and Commissioning
Installation and commissioning item preparation list
For the glove box you ordered, please prepare the following items required for installation and commissioning:
1. Two bottles of pure argon gas(or nitrogen) with a purity of 99.99%.
2. One bottle of high-purity argon gas(or nitrogen) with a purity of 99.999%.
3. One bottle of argon-hydrogen (or nitrogen-hydrogen) mixed gas.
The hydrogen content is 5% to 10% (recommended to be 8% for the best effect), and the rest is high-purity argon gas(or high-purity nitrogen gas).
The inert gas used for items 1, 2 and 3 should be the same!
4. One pressure reducing valve for gas cylinders.
The main gauge pressure range is greater than 15 MPa, and the secondary gauge pressure range is 0 – 1 MPa (or can accurately read 0.4 – 0.6 MPa).
5. One pressure reducing valve for gas cylinders.
The main gauge pressure range is greater than 15 MPa, and the secondary gauge pressure range is 0 – 0.5 MPa (or can accurately read 0.05 – 0.08 MPa).
The thread interface of the pressure reducing valve is consistent with that of the argon-hydrogen mixed gas cylinder.
Gas and other criteria required by the system
| Working Gas | Nitrogen, Argon or Helium |
| Purity | 99.999% |
|
Quantity |
Ensure a continuous supply (generally, during the initial installation, it is necessary to purge and replace the air in the box. Each section of chamber requires approxi- mately 4000-8000 liters (standard volume) of gas). |
| Regulator | Primary valve pressure range>150bar （ 15MPa） [ >2,200 psi ]
Second valve pressure range 0~10bar （ 0-1MPa） [ 0-150 psi ] |
|
Regenerating Gas |
Depending on applications:
When Nitrogen is the working gas, use Nitrogen/Hydrogen mixture (90-95% N2， 5-10% H2） When Argon is the working gas, use Argon/Hydrogen mixture (90-95% Ar ，5-10% H2) When Helium is the working gas, use Helium/Hydrogen mixture (90-95% He, 5-10%H2) |
| Purity | 99.999% |
| Regulator | Each regeneration process for MK100 purifier needs approx. 3,000 – 4,000 L [125 –
150 cu. ft.] (Measured at standard atmospheric pressure) of gas mixture |
| Purging Gas | Use the same gas as the working gas (Share one gas source) |
| Purity | 99.99% or above |
| Quantity | When purging the glove box illed with atmospheric air, each single workstation glove box needs 4000-8000L [150 – 300 cu. ft.] (Standard Atmosphere Pressure) working gas.
For initial purging, >8000L [>300 cu. ft.] working gas is recommended |
| Regulator | Primary valve pressure range>150bar (15MPa) [>2,200 psi] Second valve pressure range 0~10bar (0-1MPa) [0 – 150 psi] |
