WEH® Fueling Nozzle TK17 H₂ 70 MPa ENR with exchangeable nozzle receiver - Product family


Fueling nozzle for hydrogen fast filling of cars at self-service fueling stations.


The WEH® TK17 H2 70 MPa ENR with exchangeable nozzle receiver was developed for refueling cars with compressed hydrogen (CGH2).
The fueling nozzle provides the same proven characteristics as the actual known TK17 H2 70 MPa.

Exchangeable data interface
The IR data interface which is located at the front part of the fueling nozzle ensures proper communication between the vehicle and the fueling station thus achieving the optimum filling level.
So far the complete fueling nozzle has had to be sent in for repair in case of damage or malfunction of the data interface. With this version of the TK17 H2 70 MPa, however, the data interface can now be easily exchanged by specially trained personnel on the spot and within a very short time. Downtimes are reduced.

Prevent fueling nozzles from freezing on the receptacle - WEH anti-freeze technology
The WEH® TK17 H2 70 MPa ENR is equipped with a purging line to allow for the hose to be flushed out with nitrogen during or after the fueling process. This can prevent ingress of moisture and formation of ice crystals when filling with pre-cooled hydrogen. Removing the fueling nozzle from the receptacle is thus facilitated even in unfavorable climatic conditions.

The accompanying mounting is also equipped with a connection for flushing cycles and enables flushing of the fueling nozzle when not in use.

Optimal safety for the operator
The continuous rubber protection offers optimal protection not only for the vehicle and the front part of the fueling nozzle against damage, impacts and weather-related influences, but also for the operator against frostbitten hands.

The internal coding for pressure range and gas type ensures that the WEH® TK17 H2 70 MPa ENR can be connected to the compatible WEH® Receptacles and also prevents the risk of confusion with natural gas.
