Solar Vacuum Tube 1.Specification:47-1500mm/58-180mm 2.Inner coating:AL-C/S 3.Max.pressure: 0.8MPa 4.ISO CE KEYMARK
Solar Vacuum Tube
Runsun Vacuum tubes assimilate the advanced 12 layers of spattering deposition Of trivalent element technology, high borosilicate glass, gradual change of ALN/AIN-SS/CU selective complex absorptive coating. And these make vacuum tubes have high performance of absorptance and low reflection ratio. Through the interlayer, vacuum has a unique effect of thermo, with its temperature up to 380 of idle sunning, performing a strong heating ability.
