PEM Hydrogen Generators: 2 to 6 Nm³/h

H Series water electrolysers use Proton Exchange Membrane (PEM) technology to produce hydrogen gas on-site. They offer turnkey solutions for medium-scale applications requiring up to 6 Nm³/h of hydrogen gas at 99.999+% purity. These units have a minimal impact on facility floor space, are easy to maintain and typically can be installed within a day.

Features

Pure hydrogen at process pressure – up to 30 barg (435 psig) hydrogen and 99.999+% purity

Economical hydrogen supply – tracks electric costs

Increased safety – no caustic chemicals

Virtually zero stored hydrogen – eliminates the risk of flooding the space

Small footprint – fraction of space needed compared to cylinders or trailers

Reliable supply of hydrogen – field-proven reliability

Fast and easy installation – typically up and running in a day

Automated – safe, unattended operation

Low maintenance – requires as little as 4 hours of maintenance per year
