vacuum tube solar 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.
