6.4 Glovebox operating modes
Box purge The circulation is switched off and purge gas is blown into the
glovebox. The purge gas can be supplied by the working gas
connection through the purifier or by an external source. This
mode is triggered by selectable conditions (H
2
0, O
2
, RH-%) de-
pending on the specific box process.
Atmosphere ex-
change
A new process requires an exchange of the glovebox atmo-
sphere.
Circulation over
multiple glove-
boxes: AND / OR
Optional circulation:
¡ Through glovebox 1
¡ Through glovebox 2
6.5 Antechamber operating modes
Materials required for a process are moved into and out of the glovebox through the ante-
chamber.
During loading, the ambient air in the antechamber is replaced step by step with working
gas. This requires several cycles of purging or evacuation and refilling. These are dedic-
ated operation modes depending on the antechamber type.
6.6 Shut down system
Switch the system off over a lengthy time
The concentration of oxygen and water vapour inside increases continuously.
The system should only be switched off for the following reasons:
- In case of an emergency.
- During extended maintenance (e.g. replacement of reactors, particle filters, valves or
window opening).
- If the system will not be used for a longer period (> 4 weeks).
Shut down in case of emergency
► Turn the main switch from the “I” position (on) to the
“0” position (off).
