Vacuum chamber glove boxes are designed to enable a loaded glove
box to be evacuated, to effect an environmental change from air
to inert gas rapidly and efficiently, and have the added advantage
of out-gassing the containment and loaded contents in the process.
This type of glove box is usually specified where there is a need
to frequently transfer large process item, typically welded components.
The glove box chamber is a large cylindrical chamber with domed
ends, (one of which acts as a hinged door fitted with seal and closure
latches) the glove ports are equipped with external hinged cover
plates and together with the window, are designed to withstand the
Due to the volume and frequency of evacuation, the evacuation equipment
normally consists of a booster pump and vacuum pump combination.
For versatile operation with smaller components, a double door
antechamber is usually attached to the main chamber.
Vacuum chamber can be designed and manufactured from about 90 cm
in diameter, which accommodates both gloves and window comfortably,
up to 200 cm diameter but with reduced physical access.
Full gas management and monitoring facilities can be supplied.
As these systems involve considerably more engineering, they are
custom designed and require a thorough understanding of the application
and process operation.
