Solar Evacuated Tube
We are a professional manufacturer of glass-glass evacuated tubes that are to be used in solar collectors. We have 19 years of experience in this line. At present, we have 40 production lines to produce 10 million evacuated tubes annually, which are of high quality. Our products include dual-target tubes, tri-target tubes, glass heat pipe and several other new products. Such tubes are easy to make because only glass is to be used and the vacuum can last because the inner and the outer tube are sealed together. The inner tube and the outer tube are made of Borosilicate 3.3, which can well resist hailstones with a diameter of 28mm. The absorbers material is Al/ N/AL the absorption efficient of which is above 0.92.
