Description

(1) Outer tank: Colourful steel or galvanized steel (2) Inner tank: SUS****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 *0 percent, higher water temperatures. (7) Vacuum tube strictly choose high-borosilicate glass 3.3 so that it has low coefficient of thermal expansion and higher intensity. Hail-resistance:*5mm (8) Insulation: *5mm 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 :*5 ***** oxidation increase wind resistance, life is longer than common frame.; Beautiful appearance.
