    Linuo inorganic superconductivity heat tubes are composed of diameter altered tubes and high efficient collecting tubes. The diameter altered tubes are made of absorption copper pipes of different diameters. They are used together with top quality “Blue E rhythmus” evacuated tubes so as to the increasing of the absorption efficiency and advantage such as no pipe cracks, long duration.
