Abstract:
1. A gas cabinet including an enclosure containing at least one gas supply vessel and flow circuitry coupled to the gas supply vessel(s), and including multiple sticks each of which is arranged for gas flow communication to a respective gas-utilizing process unit, with a vacuum source and a purge gas source being coupled to the flow circuitry and arranged for evacuation and purging of one or more of the multiple sticks, wherein the flow circuitry is valved to enable portions of the flow circuitry associated with respective ones of the multiple sticks to be isolated from other portions of the flow circuitry, so that process gas can be flowed to one or more of the sticks, while other sticks are being evacuated and purged, or otherwise are closed to flow of dispensed gas therethrough, wherein each gas supply vessel comprises a vessel containing gas and an interiorly mounted gas pressure regulator, arranged so that gas dispensed from the vessel flows through said gas pressure regulator prior to flow from the vessel to said flow circuitry coupled thereto, and wherein each of said multiple sticks is contained in the enclosure containing said at least one gas supply vessel.
