We products diameter 47,58, meters in length is 1.5 m /1.8 m / 2.0 m,multiple graded AI-N/AI specifications selective coating the entire structure of the coaxial double glass vacuum tube solar collector, three-cavity, the three executives interference coating. We look forward to solar industry colleagues to inspect and guide negotiations, and create a glorious industries.
The thick-walled tube is heavier and thicker. Resisting the better withstand natural conditions,.the vacuum tube in the north so as to further enhance the anti-freezing cold in winter.
