Solar tube

The out surface of the ineer tube is double coated with stainless steel and copper when adopting the newest magnetron sputtering coating technology. This type of selective coating (SS-C/ Cu) can withstand very high temperature. This is important because the tube is exposed in high temperature to evacuate the gas in the jacket between the inner tube and the outer tube. The solar energy absorption ability should be above 93%.
