Hydrogen cooling system SUK 350L

  • Hydrogen cooling system SUK 350L offers innovative temperature control solutions to meet the challenges of handling hydrogen, which arise in the refueling of hydrogen vehicles.
  • Refueling at a pressure of 700 bar causes high compression of the remaining gas in the tank and heats it up. Therefore, the hydrogen must be pre-cooled to absorb this heat energy.
  • LAUDA has modified an ultracool circulation chiller for this purpose, to achieve the required temperature. Even lower temperatures are required for the actual refueling process −40 °C is required for pre-cooling.
  • Accumulator has the advantage that the dispenser is immediately ready when a vehicle drives up.
  • Heat energy is discharged indirectly via the liquid heat carrier over a distance of 30 to 40 meters. This is a real advantage, as a cold temperature of −40°C is needed as close as possible.
  • Cooling capacity must also be safely provided when the ambient temperature is between −20 and 42 °C, which is now a widespread specification in central Europe, due to rising (outdoor) temperatures. In this respect, the system is usually located in the open air.


  • Lowest temperatures such as −40°C can be achieved by this hydrogen cooling system with output power of 20KW
  • Heat energy is discharged indirectly via the liquid heat carrier over a distance of 30 to 40 meters. This is a real advantage, as a cold temperature of −40°C is needed as close as possible to the fueling station

Use cases

  • We will provide around 20 process cooling units for a French manufacturer of hydrogen filling stations until June 2022. These will be responsible for an essential part of the refueling process, cooling the hydrogen to -40 °C as part of the application. The filling stations will be used throughout Europe
