three-target coated solar vacuum tube

As one of the most important components for a solar water heater, solar tube should be made of great material and have good conductivity of heat.

1) This collector tube adopts magnetron sputtering coating technology

2) Structure: All glass coaxial dual tubes

3) Material: High borosilicate glass 3.3

4) Coating: Cu/Ss-Aln/Aln high efficient selective absorptive coating and vacuum heat insulation could get higher heat and have high performance of absorptance and low reflection ratio and performing a strong heating ability.

5) Vacuum pressure:5×10-4 Pa.

6) Usage life: more than 15 years.
