solar collector: 1.copper layer 2.ss aluminumnitride metal ceramic 3.aluminumnitride layer

solar collector :

Advantages Scientific and reasonable Water inlet and outlet are located in the lower parts of the water tank with easy installation. It reduces the calorific loss. There is no dead angle area inside the water tank. Superior material the vacuum tube features:

1. metal reflecting layer(copper)

2.absorbance layer(ss aluminumnitride metal ceramic)

3.remittance reducer layer(aluminumnitride)

4.Coating Ss-ALNselective compound absorb coating

5.Absorbance :0.96

6.Vacuum degree

7.advanced technology:Our company use 3 target magnetron sputtering plating technology,which introduce from Germany and also called interferometer coating technology.

Non-pollution, effectively protect the environment, energy saving, extremely low use cost at ordinary times. Once invested, you will benefit from it forever. You may withdraw the cost within 2 or 3 years.
