Solar Glass Vacuum Tube (LQ-BE-A74)

Product Description

Vacuum Solar Tube
We are a professional manufacturer of glass-glass evacuated tubes that are to be used in solar collectors.

Our products include dual-target tubes, tri-target tubes, glass heat pipe and several other new products.

The inner tube and the outer tube are made of Borosilicate 3.3, which can well resist hailstones with a diameter of 25mm. The absorbers material is SS/Cu/ N/AL the absorption efficient of which is above 0.92.

We export the tubes to several buyers in India, the USA, and Africa at present and they are becoming popular there.
Please advise us what of the tubes are of your interests and we are prepared to be of service to you.
