Gases are usually stored compressed, liquefied or dissolved in suitable cylinders. For withdrawing the gases from their containers the use of appropriate equipment play a key role in order to ensure safety and preserve the quality of the gases.
Messer offers the full range of equipment for any application. We will be glad to support you in finding the optimal form of supply.
Selection of equipment
With Messer’s equipment selection tool the suitable specialty gases equipment can be easily selected.
Type of gas
The type and quality of gas basically determine the selection of materials for gas supply equipment.
For non-corrosive, high purity gases up to 6.0 grade and mixtures the use of (chrome plated) brass equipment with metal diaphragms and corresponding sealing materials are recommended. The Messer Spectrolab product line meets these requirements and can be used for all non-corrosive, high purity gases and gas mixtures.
For corrosive gases and sensitive, low-concentration gas mixtures we recommend stainless steel components. On the one hand, it is necessary to protect the equipment against corrosion, and on the other, especially in case of low concentration gas mixtures (low ppm or ppb-range), it prevents the trace compounds from being absorbed by the surface and significantly affecting the composition of the gas mixtures. Sealing materials need to be adapted according to the type of gas. The Messer Spectrocem product line covers all the components for this type of applications.
Cylinder pressure regulator or gas supply system?
In general, there are two types of gas supply: individual cylinders at the point of use with cylinder pressure regulators or a central gas supply system. In case only one application has to be supplied with gas and the cylinder can be placed right next to the point of use, cylinder pressure regulators can be used. With a central gas supply system, consisting of pressure control panels, pipelines and tapping points at the various points of use, the gas cylinders are safely stored outside of workplaces.
