Flat plate solar collector

1)High selective titanium base coating
Introduced from Germany (alanod) into the market, used for solar energy heat collector, the high selective coating is based on coating of blue titanium and quartz, adopts one time ionization coating skills, enjoys unmatchable advantages in features, compared with generally used electroplated nickel and chromium coating, and stands for the new directions of coating technology in solar energy coating technology.

2)High efficiency
The efficiency of solar energy absorber is decidedly by the gathering effect of heat convergence in solar spectrum. The high absorbing efficiency to the solar radiation is the basic condition, and titanium base coating should be the advanced direction for the future development of flat plat solar energy heat collecting technology. The most complicated part should be how to store solar energy into the heat storage system. This coating is not only a high absorbing coating but also store the heat into the inside of absorber while reducing reflective. The result prove that if we use this blue coating technology of titanium and quartz in solar energy heat collector, the system working efficiency can also be greatly improved under the condition of cloudy weather. And the same time, the special tube technology used by Meirun group can reduce the heat loss in tube conduction and increase efficiency.
