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
