Solar Conductivity Tube

Superconductivity tube: the difference in structure lies in the copper heat pipe inside it and most of the radiation from the sun is absorbed by this sealed heat pipe which contains an anti-freeze type liquid.

It has many advantages as follow：

a. the pipe is made of super conductive oxygen-free copper. The general solar tubes transfer the heat energy by the water, but the superconductive tube with the smallest surface ,can transfer the heat to a long distance by the copper pipe and the heat spoilage is almost zero ,possessing a very high heat conducting efficiencyand a high speed.

b. No water inside, can protect from freezing or boiling ,more reliable and safe.

c. The evacuated tube with the super conductive heat pipe is the most advanced technology in the world.

d. long service life and graceful appearance keeps eco-friendly and be your best choice.
