Normal Solar Vacuum Tube

Product Detailed

normal solar vacuum tube 1) competitive price 2) environmental friendly 3) energy saving and convenience 4) ISO CE

Specification:

Feature

Its membrane layer at bottom is typically made of aluminum. Absorption layer and antireflective layer is compound of Nitrogen and aluminums ion. This bears high thermal conductivity. And the membranous layer is about 0.3 micron.Normal solar vacuum tube is very popular among solar tubes because it not only owns the mature production process, but also has the competitive prices.
