C Series

PEM Electrolyser

10-30 Nm³/h

The C Series electrolysers are ideal for a variety of industrial applications. Producing up to 30 Nm3/h of hydrogen gas at 99.9998% purity, these units replace the need for hydrogen tube trailers or liquid hydrogen storage. They can be containerized, and offer facilities flexible siting and reduced operational safety risks associated with delivered hydrogen.
