WEH® Fueling Nozzle TK20-S1 H₂ 70 MPa ENR
The WEH® TK20-S1 H2 70 MPa ENR Fueling nozzle with exchangeable data interface (ENR = exchangeable nozzle receiver) was developed for fast filling of cars with compressed, gaseous hydrogen (CGH2 ). Through to the larger nominal width, refueling in medium flow with 90 g/s or higher is possible. In addition, this filling coupling is designed for a maximum operating pressure of 96.25 MPa (= MAWP according to ISO 19880-1:2020).
In addition, the new TK20-S1 H2 70 MPa ENR has the same tried and tested features as the already well-known TK17 H2 70 MPa ENR. The fueling nozzle is additionally equipped with a purging line that allows purging with nitrogen during and after refueling process. This can prevent ingress of moisture and the formation of ice crystals during filling with precooled hydrogen.
The WEH® TK20-S1 H2 70 MPa ENR offers optimum safety for the operator thanks to the locking mechanism. The Fueling nozzle remains connected to the receptacle until the locking mechanism is released by the operator.
