    1. Detailed information

    Purple Golden Solar Vacuum Tube

    Solar vacuum tube can be classified into three categories according to the crafts: Normal Solar Vacuum Tube, Three Layer Solar Vacuum Tube and Purple Golden Solar Vacuum Tube.

    Comparing with Normal Solar Vacuum Tube, Purple Golden Solar Vacuum Tube has the different membrane structure, which contains Infrared-reflection layer, Absorbance layer and Anti-reflection layer. What’s more, there are two layers in Absorbance layer, which contributes to the higher absorptive ratio and lower emission ratio. It has the very excellent efficiency of absorbing the heat.

      Purple Golden Solar Vacuum Tube is made on the basis of Three Layer Solar Vacuum Tube, the difference lies in the color of coating material on outside tube. Besides, the time of metallic-membrane plating is comparatively longer than others, the chemical compound in the absorption layer keeps very pure, which invariably leads to the high absorption rate.
