(1)Outer tank: Colourful steel or galvanized steel
(2) Inner tank: SUS304-2B food-grade stainless steel; thickness≥0.4
(3) Sealing Ring: Excellenrt Silica gel material. life is twice longer than common Silica gel.
(4) Cap of;water tanks: aluminium-alloy thickness≥1.0
(5) Vacuum tuber: High-efficient ;vacuum tube
(6) 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.
(7) Vacuum tube strictly choose high-borosilicate glass 3.3 so that it has low coefficient of thermal expansion and higher intensity. Hail-resistance:25mm
(8) Insulation: 55mm polyurethane ; keep heating; ,reasonable density ,excellent insulation
(9) 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.
(10) Automatic operation: Digital controller shows water temperature and water lever,water loading automatically ,heating automatically ,controlling automatically.
