The WEH® TK17 H2 35 MPa ENR with exchangeable nozzle receiver was developed for refueling fuel cell electric cars with compressed hydrogen (CGH2).
The fueling nozzle provides the same proven characteristics as the actual known TK17 H2 35 MPa without 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 35 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.
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 TK17 H2 35 MPa ENR is additionally equipped with a purging line, that allows purging with nitrogen during and after 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 internal coding for pressure range and gas type ensures that the WEH® TK17 H2 35 MPa ENR can be connected to the compatible WEH® Receptacles and also prevents the risk of confusion with natural gas.
