ROTAREX has over 100 patents – most of them representing major industry-breakthrough technologies. They created the tied-diaphragm cylinder valve technologies now widely used in Ultra High Purity Gas (Electronic gases) applications. They pioneered the integrated valve technologies now widely used in medical gas applications. The European Space Agency (ESA) chose ROTAREX when they needed special cryogenic valves for their Ariane Rocket fuel coolant systems – as did the CERN particle accelerator project when they needed high-performance pneumatic line valves to power their billion-euro particle collider. Today, ROTAREX enjoys the reputation as the innovation and technology leader in its industry.

95% of their products are manufactured in Luxembourg – where high-precision machining and rigorous quality procedures ensure that each product meets the ROTAREX standard of technical excellence. In the world of gas equipment, “Made-in-Luxembourg” became the leader in terms of technical quality. Although ROTAREX is such a fast-growing global industry leader – it maintains a focus on local service. ROTAREX is a fourth-generation Luxembourg family-owned business who values customer relationships, and working face-to-face with customers to ensure their needs are met.
