Modern laboratories often use H2, CH2, O2, N2, Ar, He and other gases in testing and analysis. The traditional laboratory gas supply method is to set a gas cylinder near each gas point, which causes repeated construction, brings safety risks, and affects the indoor beauty. Centralized gas supply has become a general trend for laboratory development and construction because of its safety, convenience, economy and beauty.

Laboratory gas supply mode

1, dispersed gas supply, the same gas with less gas points, and dispersed distribution is used. 2, centralized gas supply, the same gas with more gas points, and divided centralized distribution is used.

Advantages of centralized gas supply

1, easy to operate, good safety, a unified set of gas cylinders, the gas according to flammable and non-flammable nature of the distinguish placement. And take ventilation, fire and explosion-proof, emergency cut off and under-pressure alarm measures to facilitate cylinder replacement, management, safety and security.

2, stable air pressure, high purity, through the multi-stage decompression of gas supply, the gas pressure and flow rate of each gas point can be accurately adjusted, real-time display, by installing a gas path purge replacement system, high gas purity.

3, economical and practical, neat and beautiful, can reduce the repeated construction of the same gas supply gas bus, gas supply pipeline unified planning, neat and beautiful.

The composition of the centralized gas supply system

1, the gas source part: the gas cylinder (gas source) is centrally placed in a specific gas cylinder, and the high pressure gas is converted into low pressure gas through the primary pressure reduction system (gas regulator or bus).

2, the pipeline part: through the (316#) stainless steel pipeline to send the gas to the instrument equipment use point in each room on each floor.

3, the terminal part: the instrument before the configuration of the globe valve and two level pressure reducer, you can make the switch of the gas path, accurately adjust and display the gas pressure.
