Solar Heater High Absorption Vacuum Tube

Product Introduction
KD-VT-HA solar heater high absorption vacuum tube is made of borosilicate glass. It adopts the advanced 12-layer ALN/ALN-SS/CU selective absorptive coating by spattering. This makes the solar evacuated tube highly absorptive and highly resistant to high and low temperatures. In addition, the double walled glass tube features a low reflection ratio. The interlayer produces a unique thermal effect, making the surface temperature reach up to 380℃.

The vacuum tube, a key part of the solar water heater, decides the performance of the solar water heating system. With the inner wall color of red, our high absorption vacuum tube has high heat efficiency and is reasonably priced. Even at a temperature of -20℃, it can still work normally.
