All-glass evacuated solar collector tubes are the key component of solar collector in water heaters, which consist of two glass tubes. The outer tube is made of extremely strong transparent borosilicate glass that is able to resist impact from hail up to 25mm in diameter. The inner tube is also made of borosilicate glass, but coated with a special selective coating, which features excellent solar heat absorption and minimal heat reflection properties. The air is evacuated from the space between the two glass tubes to form a vacuumed space, which eliminates conductive and convective heat loss. Evacuated solar collector tube could still work efficiently even on cloudy days, because it is able to absorb the energy from infrared rays passed through clouds.With the ratio of solar transmission of borosilicate glass 3.3 r≥0.89 and thermal expansion below 3.3 x 10-6/k, the collector tubes can make full of the solar radioactive energy and own excellent heat-resisting performance as well as high mechanical intensity.The surface of the tubes is completely rinsed by the water removed ion, which make the selective coating adhered to the tubes firmly and guaranteed the efficiency and service life of the collector tubes.Advanced skills in plating the selective coating and efficient system in evacuating vacuum provide the absorption of selective coating Α≥94.5% and the emission ε≤5.5%, which greatly improved the performance of the collector tubes.The patented technologies in circular sealing and annealing system enable a solid linkage between the inner and outer tube and fully eliminate the internal stress, solving the difficult problems of liable damage in the sealing parts.The vacuum evacuated collector tubes can be applied not only in the water heater under various weather conditions, but also in the hi-tech areas such as refrigeration and generating electricity.Outer packing:Foam or cartonCarton dimensions:1) Tube (47/37 x 1,500mm): 1,580 x 330 x 200mm2) Tube (58/47 x 1,800mm): 1,880 x 350 x 170mm3) According to customers requests
