Distilling apparatus or condenser for obtaining fresh water from salt water, with handwritten explanation on paper (NG-MC-1108-2). The system has two separate water flows: cold seawater from outside the ship enters the outer cylindrical vessel below and, heated, leaves the apparatus from above and is led outside the ship again; steam is introduced through the top of the apparatus and distributed into several pipes, where it is cooled by the seawater in the outer vessel and, once condensed, is tapped off as fresh water at the bottom. Two taps are also attached to the wall of the outer vessel, connected to a pipe. The closures of the outer vessel and the distilling pipes are fitted with bolts and nuts.
