Solar Thermal Collector

Choosing high selective Titanium base coating, using best heat conductivity TU1 material as heat collecting board, with our specific technology and complete sealing design, we make sure that maximized heat can be stored into the water box. Meirun flat plat solar energy heat collector special skills make breakthrough in anti-freezing, so it can also be used in high-latitude area. It enjoys advantages like high anti-freezing ability, high heat efficiency, large capacity, high cost-effective, burdening, sunshine resistance. The special heat conductive media is heated in cupper tube, quality reliable, avoid maintenance for the long span of 15 years. The titanium base coating is the only substitution to the nickel and chromium coating by the titanium and quartz, and the production process will not pollute water and air.

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.
