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 99.9995% purity. These units have a minimal impact on facility floor space, are easy to maintain and typically can be installed within hours.

Features

  • Pure hydrogen at process pressure – up to 30 barg (435 psig) hydrogen and 99.9995% 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
