AIR LIQUIDE offers a full range of equipment for the handling of pure gases and mixtures. Our equipment is designed for high-purity gases and calibration mixtures. Best features include: electropolishing walls, reduced dead space, butt-welded fittings... All ALPHAGAZ™ equipment for pure gases and mixtures is helium leak-tested with a mass spectrometer to: 3.10^-7 to 10^-9 mbar.l/s of helium for ALPHAGAZ™ 2, 10^-6 mbar.l/s of helium for ALPHAGAZ™ 1.

• Equipment for cylinders

Cylinder regulators : Pressure regulators, more commonly called "regulators" are devices that lower the pressure of a gas to a stabilized value. This reduced pressure is to be kept constant for a range of given flow rates, even if the gas source pressure is variable (case of a cylinder).


• Equipment mounted on gas lines

In line valves : used to open, close, or isolate a circuit.

Flow Control valves: used to regulate the flow of your gas delivery system.

Pressure regulators : used to lower the pressure of a gas to a stabilized value.

Drain tee : Purges provide safety by preventing the release of toxic or corrosive gases into the workplace when changing cylinders, corrosion resistance by preventing corrosive or halogen gases from coming into contact with atmospheric moisture, and purity by preventing air from infiltrating high purity systems at the time of cylinder change.

Miscellaneous small equipment : purifiers, relief valve, etc.: used for optimal and secure management of your distribution system.
