1. Outer tank: Colourful steel or galvanized steel<o: P>
2. Inner tank: SUS304-2B or 316 food-grade stainless steel thickness≥ 0.4
3. Sealing Ring: Excellenrt Silica gel material. Life is twice longer than common Silica gel.
4. Vacuum tuber: High-efficient vacuum tube
*High-Efficient heat-collection function: New generation of vacuum tubes, use molecular nanotechnology, greatly enhance heat-absorption by 20 percent, higher water temperatures.
*Adopts the international advanced film-coating technology, solar thermal conversion rates extremely high, absorbing heat even if the cloud weather.
*Vacuum tube strictly choose high-borosilicate glass 3.3 so that it has low coefficient of thermal expansion and higher intensity. Hail-resistance: 25mm<o: P>
5. Insulation: 55mm polyurethane keep heating do with aging the cell is small and uniform reasonable density excellent insulation
6. Frame: Thicker galvanized steel, Anti-corrosive. And Anti-ultraviolet, installed in the slope and flat place freely. Strengthen hail-resistance. Angle: 20-80 degree. Through oxidation process. It increase wind resistance., life is longer than common frame. Beautiful appearance.
7. Automatic operation: Digital controller shows water temperature and water lever, water loading automatically, heating automatically, controlling automatically. <o: P>
How it works
The design of this type uses the all-glass evacuated solar collector tubes as the heat absorb element. The high vacuum degree of the clearance between the outer and inner tube can reduce the heat emission which caused by convection and conduction to a very low level. All-glass evacuated tube transfers sun energy into heat energy by high absorption rate and low emittance rate of layer films. Depend on the different density between the hot water and the cold water, a cycle created in the tube which hot water ascending and cold water descending status. Keeping natural circulation like this, the water in the tank will be heated. <o: P>
