The WEH® TSA1 H2 Breakaway Coupling offers additional safety for your car fueling station. The breakaway is installed between the dispenser and the filling hose resp. filling and venting 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 the connections between dispenser and hose sealing both ends. This protects largely the receptacle, the fueling nozzle and the dispenser against damage. The detached coupling can be easily reattached and placed back in service after having been function tested.
The integrated filter 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. The breakaway is also available without gas recirculation.
The TSA1 H2 for fueling nozzles with data interface additionally contain a dispenser mounting incl. data cable for the data interface.
On request we also offer complete nozzle-hose-assemblies consisting of a fueling nozzle, a hose set and a breakaway coupling.
