ABSTRACT:
A gas cabinet including an enclosure containing at least one gas supply vessel and flow circuitry coupled to the gas supply vessel(s). The flow circuitry is constructed and arranged to flow dispensed gas from an on-stream gas supply vessel to multiple sticks of the flow circuitry, with each of the multiple sticks being joined in gas flow communication to a respective gas-utilizing process unit. The flow circuitry is valved to enable sections of the flow circuitry associated with respective ones of the multiple sticks to be isolated from other sections 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 dispensed gas flow therethrough.
