The german industrial gas company, Messer GmbH, has released a new Duplex bundle which enables gas supply at pressures of both 200 and 300 bar, without the need for costly equipment modifications.

Operations with a high demand for technical gases in cylinders are usually supplied with 200-bar compressed gas cylinder bundles. In recent years, however, 300-bar bundles have also gradually conquered the market, because they have 50% more capacity than 200-bar bundles. But to draw gas from these bundles many production plants incorrectly connect gas systems.

For this case, Messer, the largest management-owned industrial gas specialist, has developed a new type of bundle: filled with 300 bar filling pressure. The Duplex bundle has two connections, one of them is equipped with a pressure reducer integrated within the bundle, which reduces the extraction pressure to below 200 bar. This makes it possible to consume gas at 200 or 300 bar without any modification of the technical installations - and without the costs associated with such modifications. According to Messer, the Duplex can cover the full demand of major consumers which have multiple consumption points at 200 and 300 bar within their operation.


Duplex bundles from Messer are fitted with quality line pressure regulators from Spectron. These pressure regulators ensure high control accuracy with the same maximum delivery volume as a conventional bundle. Duplex bundles are available for all standard types of gas, such as argon, oxygen, nitrogen and argon mixtures.

According to the German company, over coming months, Messer will gradually introduce the new type of bundle to specific countries and for specific products.
