Specifications and Product Details:
Solar vacuum tube:
Feature:
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°C of idle sunning, performing a
strong heating ability.
