Rotarex S.A.
Take over account

Rotarex S.A. is a leading supplier of gas control equipment across the full hydrogen value chain, spanning high-pressure cylinder and bundle valves for compressed hydrogen storage and transport in Multiple-Element Gas Containers (MEGCs) and tube trailers, bellows valves for cryogenic liquid hydrogen circuits, and valves and regulators for hydrogen automotive applications. The company's D615 and D655 high-pressure bundle valves, rated to working pressures of 500 bar and temperatures as low as -20 degrees C, address hydrogen's small-molecule sealing challenge with tightness below 10 to the negative 3 mbar-liters/second, and are homologated to ISO 10297:2024 for MEGC applications; the D655 adds pneumatic actuation for remote-controlled tube trailer and MEGC operation. Rotarex Puretec, the company's ultra-high-purity valve division, produces UHP cylinder valves (diaphragm, packed, O-ring, and VIPR types) assembled in cleanroom conditions for hydrogen energy, space propulsion, and scientific research applications requiring the utmost gas purity.
