For several years, DÉFI SYSTÈMES has been strengthening its position in "gas process" applications, particularly in the field of hydrogen. Driven by the desire to internalize manufacturing operations as much as possible, in 2020 we acquired an ORBITALUM orbital welding equipment, dedicated to the production of our vast array of equipment.


This investment was accompanied by the recruitment of an experienced pipe fitter, who carries out the welding, bending and assembly of the process lines.

With this know-how, DÉFI SYSTÈMES now produces all the gas assemblies dedicated to its equipment, for high purity applications (hydrogen cell test benches) or nuclear applications (tritium gas processes).
