Specification:

1. Shell material: white pearl board, thickness 0.32mm

2. Inner core material: aluminum alloy, subjected to anti-corrosive treatment

3. Insulated material: polyurethane, thickness 30mm

4. Full-glass vacuum tube material: borosilicate glass 3.3

5. Full-glass vacuum tube size:  58/1800

6. Full-glass vacuum tube color: blue and violet gold

7. Full-glass vacuum tube film: red copper/stainless steel/aluminium alloy

8. Solar absorption efficiency:0.93~0.95(Am1.5)

No water in the full-glass heat tube, the working medium is gasified to heat a condensing section so as to finish the heat exchange with water in the connection collector, so that the solar heat collector has the characteristics of quick start, high efficiency, one-way heat conduction and high anti-freezing property.
