The HAM Group has developed a new nozzle to supply fuel to heavy vehicles that allows to increase the safety and to minimize the emissions of polluting gases. The disconnection of the nozzle is carried out without any gas emission in the air. This operation eliminates the risk of burn and possible creations of explosive atmospheres. It also highlights the disappearance of leakage or loss of liquid from the seal of  the tank of the truck,  so frequent, thanks to the new design of anchorage and closure. With a double anchoring system that increases safety in the supply of LNG,  the innovative nozzle  is a further step towards the normalization of the refueling operation making it similar to a conventional fuel loading.
