Evacuated Tube Solar Collector With EN12975


The pipeline is made of red copper and conducted by heat transfer medium liquid. Water cannot flow in vacuum tubes and operated when confined. The crust uses aluminum alloy mould material of high strength with air flow design. It is furnished in good style.
Can endure high pressure when it works.
Module design, optional combination, which can meet the demand of large water consumption.


1.Manifold : red copper
2.Manifold Casing: aluminum alloy
3.Glass tube dimensions: 58mm x 1.8m
4.Heat preservation: 72hrs
5.Hail resistance: 25mm
6.max pressure: 10 bar
7.Coating of vacuum tube: Cu-SS-Al/N/Al

8.Vacuum tube material:High borosilicate galss3.3
9.Heat Pipe: anti-freezing > -35°C
10.Inner diameter of inner tube :37mm or 47mm
11.Outer diameter of outer tube :47mm or 58 mm
12.Thickness of glass tube:1.6 mm or 2.0 mm

The working principle of solar collector is very simple.

1.Solar Absorption: Solar radiation is absorbed by the evacuated vacuum tubes and converted into heat.

2.Solar Heat Transfer: Heat pipes conduct the heat from within the solar tube up to header.

3.Solar Energy Storage: Water or water mix is circulated through the header, via intermittent pump cycling. Each time the water circulates through the header the temperatures is raised by 5-10oC / 9-18oF. Throughout the day, the water in the storage tank is gradually heated.
