The break-away coupling type TSA5 H₂ (bus/truck) offer additional safety for your fueling station. The coupling consists of a receptacle and a nozzle which are installed between the dispenser and the fueling hose.
In the event of accidental deployment, e.g. driving a vehicle from the dispenser with the nozzle remaining in the vehicle fuel port, the coupling will separate and protect your dispensing equipment against damage. The detached coupling can be easily reattached and placed back in service after having been function tested.
The integrated filter system provides clean hydrogen and is easy to maintain.
The WEH® Breakaway Coupling consists of a coupling body, a receptacle insert and a gas recirculation with check valve.
On request we also offer complete nozzle-hose-assemblies consisting of a fueling nozzle, a hose set and a breakaway coupling.
