Highly-absorptive Vacuum Tube
Description
*Features:
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.
