Solar Heater High Absorption Vacuum Tube
Solar Heater HighAbsorption Vacuum Tube
Product Introduction
KD-VT-HA solar heater high absorption vacuum tube is made ofborosilicate glass, which applies the advanced 12-layer of spatteringdeposition technology of gradual change of ALN/ALN-SS/CU selective absorptivecoating. This makes the vacuum tubes highly absorptive and highly resistant tohigh temperatures and low temperatures. In addition, the vacuum tube features alow reflection ratio. The interlayer produces a unique thermal effect, making thesurface temperature reach up to
The vacuum tube, the keypart of the solar water heater, decides the performance of the heating system. KD-VT-HA high absorption vacuum tubehas high heat efficiency and is reasonably priced. Even at a temperatureof–
