A filling station for filling a liquid cryogenic refrigerant from a supply tank to a receiver tank, the filling station comprising a flash tank between the supply tank and the receiver tank, adapted to de-pressurize the refrigerant that is transferred from the flash tank to the receiver tank, resulting in formation of a liquid cryogenic refrigerant phase and a vapour cryogenic refrigerant phase within the flash tank, and to phase separate the liquid and vapour cryogenic refrigerant phase, and a pump between the flash tank and the receiver tank, adapted for pumping the refrigerant out of the flash tank to the receiver tank, wherein the flash tank is equipped with a level control unit that is arranged to keep the level of the liquid cryogenic refrigerant phase within the flash tank at a predetermined minimum. |
