Standard infrared nozzle for universal FCEV compatibility.

Engineering Analysis Layout
Safety Protocols

Fail-Closed. Buffer-Less.

Our design priority is absolute safety over peak efficiency. We minimize stored energy to eliminate catastrophic failure modes.

  • Buffer-Less Design: HP storage limited to <10 L, minimizing potential energy release.

  • SIS Logic: Independent hard-wired safety circuits (SIS) bypass software for critical stops.

  • Zone 2 ATEX: Full compliance with ATEX 2014/34/EU for residential environments.
