Cryostar has released its brand new LNG Dispenser, called the LNG Dispenser 2.0.

The production of the device is thanks to Cryostar’s know-how in LNG refuelling stations technology and capitalizing on its strong experience acquired from the design and start-up of more than 90 LNG/LCNG fuelling stations worldwide

The LNG Dispenser 2.0 is a unique piece of equipment in the world, designed for LNG refuelling stations, for fleet operators and for lorry drivers using LNG as a fuel for their trucks.

LNG, which causes less pollution and is cheaper, is an alternative fuel to conventional fuel such as diesel, for example.

Behind the simplicity of the new dispenser stands a concentrate of technology, combining reliable, automated, safe and user-friendly designed equipment to meet customer satisfaction. Thus, the new design of the LNG DISPENSER 2.0 offers to reduce drastically gas losses, and allows for a more convenient use of the LNG dispenser.

The new LNG Dispenser benefits from Cryostar’s latest innovations:

  • Coriolis flowmeter and electronic calculator validated for weights & measures approval according to MID directive: the legal threshold of 1.5% imposed by the European Directive on “Weights and Measures” is not only reached but even exceeded on the Coriolis mass flow meter for LNG.
  • Independent Cryostar CRYOFUELTRONICTM electronic card - The proprietary CRYOFUELTRONICSTM electronic card is designed to manage the entire automatic refuelling process controlling valves and instrumentation for tank venting, flow meter cooling down and vehicle refuelling. The electronic card ensures a safe refuelling process for use in ATEX zone 1 and is fully suitable to be weights and measures approved following the MID directive.
  • The Optional Vent back Coriolis flow measurement device in the vent line calculates precisely the volume of gas transferred and quantifies exactly the mass filled as well as that ‘recovered’ from the truck, making it unique in its kind globally. Until now, the volume of gas ‘vented’ was not accounted for, making this innovation a true value added to the customer and helping to significantly optimise the installation.
  • Enhanced communication with station supervision system using Modbus for communication with PLC and IFSF protocol for communication with payment system. In addition a simple communication mode through a single contact for pump start and stop is available.

Ergonomics

Cryostar paid special attention to the ergonomics of the LNG dispenser:

  • Improved design

The design of the dispenser has been improved to be user friendly and is dedicated to LNG refuelling. Thanks to the position of the dispenser screen the operator safely stays behind the dispenser during the refuelling and is not blocked in-between flexible hoses during refuelling operation. Moreover, the dead-man operation button is placed in such a way that it is easy to handle.

  • Enhanced flexible hose layout

The layout of the flexible hoses has been improved to ensure a longer lifetime. They are now hanging from the top of the dispenser. In addition, a specific support is installed in order to ensure a good bending radius when the nozzle is replaced onto his receptacle.

  • Improved user interface

In order to make the use of the dispenser much more user friendly only one “dead-man” button has to be pushed to start the refuelling sequence. There is no other buttons except the Emergency stop Button. The dispenser automatically detects flexible hose disconnection.

The graphical interface of the screen looks like any standard fuel display with 3 lines for the total weight, total price and price per kg. An additional instruction line shows useful information to the operator and describes each refuelling steps. In addition, a fifth line allows for either specific messages or other information, such as a Diesel litre equivalent display.

Safety

Safety is paramount when using the dispenser and Cryostar has worked hard to cover aspects such as:

  • The absence of sparks is ensured when connecting and disconnecting the connector to the lorry (earthing).
  • The proper functioning of the air pistol is important when cleaning the connector to remove all traces of ice. When fuelling, the driver is positioned away from surfaces with cryogenic temperatures, where there is a risk of frostbite.
  • Correct positioning of the flexible hoses, the buttons and the clamp, but also the absence of constraints for the operator.
  •  Increased service life of the hoses, thanks to their configuration.
  • Emergency stop button directly connected to the station control panel allowing a complete shutdown of the station.

Performances:

  • Short fuelling time: 160l/min (80kg/min)
  • Truck tank higher refuelling capacity: 3min for 450l tank
  • Refuelling system compatible with every existing trucks models worldwide: 3bar (-150°C Cold LNG) or 8bar (-130°C saturated LNG)
  • Optimisation of the refuelling level through overshoot function
