The HydrogenSmartFueller, HSF for short, is a adaptably designed dispenser with control software, specially developed for hydrogen filling stations. The HSF is available with a 350bar or 700bar nozzle. In order to allow refuelling from both pressure levels, the HSF is also available with two dispensing points. This modularity allows a wide range of applications, which makes the HSF perfect for refuelling of any kind of vehicle.

Small footprint – big impact

The HSFs compact design enables a broad application range. The HSF stands tall at around 3m height, and with a footprint of under 1,45m². The optional roof protects customers from rain and sun.

Smart und Flexibel

Our Hydrogen Smart Fueller is designed as controls unit of the H2 fuelling station. Other parts, like compressor systems, supply tanks or cooling solutions play only a minor role. The HSF can be used as a modern standalone replacement for mechanical overflow devices of yesteryear.

The modular design of the HSF allows it to be adapted to the most diverse customer requirements. The main focus is on seamless integration into the overall system. We can offer nearly limitless options when it comes to adaptability and expandebility, thanks to our own, customizable software.

N2 Flushing connection

  • Enables the use of the HSF as a first fuelling unit


Writing good software is, due to safety requirements, on of the more complex parts of a hydrogen fuelling station. Our software allows us to fully customize the fuelling process, so that we comply with standards where they exist: SAE J2601 under 10kg, cooled, JPEC over 10kg, cooled.

However, our experience has shown that customer requirements often exceed the standards and we’re happy to develop, in coordination with vehicle manufacturers, new and exciting fuelling solutions for every use-case.

H2 fuelling stations all over the globe use our software and operators trust us with our expertise when it comes to software, as well as electronical planning for H2 fuelling plants.
