WEH® Fueling Nozzle TK20-S3 H₂ 35 MPa ENR Medium-Flow
The WEH® TK20-S3 H2 35 MPa ENR Medium-Flow 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 with 120 g/s or higher is possible. In addition, this filling coupling is designed for a maximum operating pressure of 48.125 MPa (= MAWP according to ISO 19880-1:2020).
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-S3 H2 35 MPa ENR Medium-Flow 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.
