solar vacuum tube High quality solar vacuum tube with 1 or 3 layers elements planting, solar absorbance can reach more than 94%.

* Features of solar vacuum tube:Vacuum tubes assimilate the advanced 12 layers of spattering deposition of trivalentelement technology, high borosilicate glass, gradual change of SS-C/CU selectivecomplex absorptive coating and these make vacuum tubes have high performanceof absorptance and low reflection ratio. Through the interlayer, vacuum has aunique effect of thermo, with its temperature up to 380 degrees of idle sunning,performing a strong heating ability* Optional size: 47 x 1,500mm / 58 x 1,800mmPacking: Export carton
