Evacuated tube solar water heater/solar water heater/solar heater/solar energy water heater
Outer tank: SUS304-2B stainless steel or colourful steel or galvanized steel
Inner tank: SUS304-2B food-grade stainless steel thickness≥ 0.4
Sealing Ring: Excellenrt Silica gel material. Life is twice longer than common Silica gel.
Cap of water tanks: Aluminium-alloy thickness≥ 1.0
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
Insulation: 55mm polyurethane keep heating do with aging the cell is small and uniform reasonable density excellent insulation
Frame: Thicker galvanized steel, Anti-corrosive. And Anti-ultraviolet, installed in the slope and flat place freely. Strengthen hail-resistance. Best angle for the winter: 45 degree. Through oxidation process. It increase wind resistance., life is longer than common frame. Beautiful appearance.
Automatic operation: Digital controller shows water temperature and water lever, water loading automatically, heating automatically, controlling automatically.
