Shell material: white pearl board, thickness 0.32mm

Inner core material: aluminum alloy, subjected to anti-corrosive treatment or stainless steel

Insulated material: polyurethane, thickness 55-60mm

Full-glass double vacuum tube material: borosilicate glass 3.3

Full-glass double vacuum tube size: 47/1500 47/1800 58/1800

Full-glass double vacuum tube film: red copper/stainless steel

Full-glass heat tube vacuum: P≤5.0*10-3(Pa)

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.
