solar collector

Automatic operation: Digital controller shows water temperature and water lever,water loading automatically ,heating automatically ,controlling automatically.

It increase wind resistance.,life is longer than common frame.  Beautiful appearance.

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.

Insulation: 55mm polyurethane  keep heating 

Vacuum tube strictly choose high-borosilicate glass that it has low coefficient of thermal expansion and higher intensity. Hail-resistance:25mm

Adopts the international advanced film-coating technology, solar thermal conversion rates extremely high, good performance even if in the cloud weather.

High-Efficient heat-collection function: New generation of vacuum tubes, use molecular nanotechnology, greatly enhance heat-absorption by 20 percent, higher water temperatures.

Vacuum tube: High-efficient  vacuum tube (with our special designed heat pipe,which will have  higher efficiency than others' )

Sealing Ring: Excellenrt Silica gel material. life is twice longer than common Silica gel.

Inner tank: SUS304-2B food-grade stainless steel 

Outer tank: SUS304-2B stainless steel or colourful steel

Certificates: EN ISO  ROHS En12975

solar collector from GTC-solar have been exported to many countries in the world.
