Compact Unpressurized Solar Water Heater

1. Outer tank: SUS304-2B stainless steel
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 o 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
5. Insulation: 55mm polyurethane keep heating do with aging the cell is small and uniform reasonable density excellent insulation
6. Frame: Thicker stainless 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.
