The most intelligent and reliable LNG dispenser
on the market today


Innovative and patented technics

A patent has been obtained for the nozzle docking bay, which is integrated in LIQAL’s latest dispenser line. This docking bay is heated and purged in order to ensure tension-free connection and de-coupling of the nozzles to and from LNG-powered vehicles, as well as long life of nozzle seals and hoses.
The latest LIQAL dispenser has been implemented at the forecourt of various LNG station operators across North-West Europe who are convinced of its benefits compared to traditional dispensing- and docking devices.
