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 nozzleis 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.
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.
