gtc-58 solar heating sytem solar water heater

solar systems, solar systems, solar systems, solar systems, solar systems, evacuatedtube solar water heater from GTC-solar have been exported to many countries in the world. Certificates:CE ISOROHS,CSA Outer tank: SUS304 stainless steel or colourful steel Inner tank: SUS304-2B food-grade stainless steel Sealing Ring: Excellenrt Silica gel material. life is twice longer than common Silica gel. Vacuum tube: 47*1500MM, 58*1800MM m SEREIS VACUUM TUBE High-Efficient heat-collection function: New generationof 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,good performanceeven if in the cloud weather. Vacuum tube strictly choose high-borosilicate glass that it has low coefficient of thermal expansion and higher intensity. Hail-resistance:25mm Insulation: 55mm polyurethane keep heating Frame: thicker galvanized steel , Anti-corrosive, installed in the slope and flat place freely.Strengthen hail-resistance. Best angle for the winter :45 degree horizontal. 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. solar water heater , solar water heater, solar water heater, solar water heater , solar water heater, solar water heater, solar water heater, solar water heater, solar water heater
