Sirius project completed: green hydrogen electrolyser validated at industrial scale with record purity
Hyter and its partners validated an AEMWE electrolyser up to 1 MW in an industrial environment, achieving hydrogen purity up to 99.999%.

FT 518 is a lever-operated device for high and medium pressure with multiple replaceable orifice.
FT 518 is an unbalanced pressure regulator.
This regulator is suitable for use with previously filtered, non corrosive gases. It is a truly top entry design which allows an easy maintenance of parts directly in the field without removing the body from the pipework.
When the built-in token relief valve is active, it prevents undesiderable slam shut trip due to minor internal leakages or ambient temperature variation.
The modular design of FT 518 pressure regulators allows to retrofit either slam shut valve or integral full monitor.
