Product Description
Compared with most flat plate design, evacuated tubular collector normally has a smaller fraction of total occupied area actually intercepting solar radiation because of the suppression of convectional and the provision of a selective surface, the efficiency value obtained with an evacuated tube collector are significantly higher than those obtained with conventional collector.

All-glass evacuated solar collector tubes are the key component of solar collector in water heaters, which consist of two layers of glass. 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 glas, but coated with a special selective coating, which features excellent solar heat absorption and minimum heat reflection properties. The air is evacuated from the space between the two glass tubes to from 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 borolisicate glass 3.3>0.89 and thermal expansion below 3.3 x 10-6 / �C, 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 competely 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 A>94.5% and emission B<5.5% which greatly improved the performance of the collector tubes.

Higher capacity VTS system is mainly used for commercial as well as industrial purpose in which evacuated tube may get upto 85� C which can minimize used of other conventional fuels.
