Specifications and Product Details:

Kaidun Highly-absorptive Vacuum Tube is made of borosilicate glass, which applies the advanced 12-layer of spattering deposition technology of gradual change of ALN/AIN-SS/CU selective absorptive coating. This makes the vacuum tubes highly absorptive and highly durable to high temperature and low temperature. Meanwhile the vacuum tube features a low reflection ratio. The interlayer gives the tube a unique effect of thermo, and the surface temperature could be as high as 380. It is the key part of the solar water heater and decides the performance of the heating system.
