200L low pressure colourful steel solar geyser

solar geyser Certificate: SRCC, Solar Keymark, CE and ISO9001

solar geyserOuter 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.

Certificate: ISO,CE,SGS, SRCC, Solar Keymark
