More safety at hydrogen fueling stations with the new WEH® TSA31-S1 H2 70 MPa breakaway coupling.

The breakaway coupling is installed directly between the filling hose to the fueling nozzle and the filling hose to the filling station. If unexpected tensile forces occur, e.g. when a vehicle with a connected fueling nozzle drives away, the TSA31-S1 H2 70 MPa disconnects the connection between the dispenser and hose in a controlled manner. Both sides are sealed pressure-tight directly after breakaway and therefore damage to the vehicle and the dispenser can be prevented as far as possible. 

The max. operating pressure of 96.25 MPa offers even more safety. If there is a malfunction, the safety valve of the dispenser opens at a pressure of 96.25 MPa. This high pressure can also reach the breakaway coupling, but the TSA31-S1 H2 70 MPa can withstand this pressure perfectly.

In the event of a breakaway, the base unit can be reused - no factory servicing is necessary. Only the receptacle insert needs to be replaced or serviced. Therefore we offer a replacement receptacle insert, to avoid downtime at the dispenser.

The WEH® breakaway coupling consists of the base unit, the receptacle insert and a holding flange, which contains the plug-in couplings for the data cable and purging cable. The integrated filter ensures clean filtered hydrogen and thus prevents damage caused by dirt ingress. The TSA31-S1 H2 70 MPa is suitable for use with pre-cooled hydrogen.
