Maximum safety when filling with H₂
Unforeseen tensile forces during refueling – for example if a vehicle with a connected fueling nozzle is unintentionally driven away – can cause damage to the filling station, vehicle or filling system. WEH® breakaway couplings reliably prevent this: they separate the connection in a controlled manner, seal both sides pressure-tight and thus ensure maximum safety. WEH offers the right solution for all common filling station concepts – whether for road vehicles, off-highway equipment or industrial applications in the heavy-duty sector.
Reusable, compact & low-maintenance – for maximum availability
Thanks to their robust design, WEH® breakaway couplings can be integrated into filling station systems to save space. Depending on the design, they can be reused after demolition – a factory repair is not absolutely necessary. This minimizes downtimes and reduces maintenance costs. In addition, an integrated filter reliably protects against impurities in the hydrogen flow. This keeps your H₂ infrastructure permanently operational and safe – even under demanding operating conditions.
