With a central gas supply system, individual work places or gas take-off stations are supplied with gas through pipeline networks. The cylinder pressure (high pressure) is reduced in the central gas supply system to low pressure. The desired working pressure or flowrate is regulated individually on the low pressure take-off stations.
With a change-over switching station is guaranteed that there is always gas in place as reserve and that there is a continuous gas supply without interruption. The flexible modular system permits individual attention to user requirements for the central gas supply system and enables the possibility for a retrospective installation expansion.
