Vogt revolutionized the commercial ice-making industry in 1937 when it built the first Tube-Ice Machine. Prior to this, ice was made in block form. Vogt engineers designed the unique Tube-Ice Machine specifically to freeze ice automatically in vertical tubes, momentarily thaw ice loose from the tubes and then cut it into short cylinders with a hole in the center. The hole is formed during the formation of the ice as a result of the falling film of water freezing inside the vertical tubes.
     Similar to the breakthrough of Tube-Ice, Vogt has now introduced a double tube design ice machine which produces fragmented ice.
