Shell material: white pearl board, thickness 0.32mm

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

Insulated material: polyurethane, thickness 5mm

Full-glass vacuum tube material: borosilicate glass 3.3

Full-glass vacuum tube size: 47/37/1.6/1500 and 58/47/1.6/1800

Full-glass vacuum tube color: black

Full-glass 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.
