2.Our advantage:

1) High efficiency production line of solar water tank.

2) Advanced production line  of solar vacuum tube

3.Feature

1) The first solar vacuum tube technical manufacturer obtaining the GOLDEN SUN certificate in Zhejiang Province.

2Three high vacuum tube,efficient and high quality

 This vacuum tube makes higher heat aborption efficiency,stronger thermal insulation property ,besides,it is able to bear splat cooling and heat,has higher strength,doesn't crack,with anti-aging,and wears well as well as with longer operating life.

3)Perfect heat-preserved cabin,be away from cold in winter

 The whole foaming technology with high temperature originates from Germany Bayer Company,whose inner tank,outer skin,end cap and insulation layer form a perfect heat-preserved cabin,the rate fo air closure reacher up to 98%.it could adapt to various severe environment,longer heat perservation and better for winter.

4) Temperature when exposed to sun without water: 250°C, 2.5 hours to boiling point if using single tube.5) Stable and reliable performance, well wind resistance.6) Simple structure and easy to assemble and install.

7) High quality with reasonable price.

8) Heat preservation: at least 72 hours. The temperature go down 3~5°C per day.
