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.

Benefits

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
