All-glass Evacuated Solar Collector Tube

The all-glass evacuated solar collector tube consists two concentric cylindrical glass tubes, the inner cylindrical tube is the absorber tube on which solar selective coating is sputtered, the jacket between the two glass tubes are evacuated to extremely low vacuum to reduce the heat loss by free convection and conduction. Top quality tubes
increase the solar yield of your solar system and reduce the aging problem. This technology can be utilized under all kinds of climate
conditions, especially better in colder area.

Features
High absorption a>0.93 (AM1.5) and low emittance e<0.06 (80 Celsius degree);
Borosilicate glass 3.3 with transmittance higher than 91%
Long service life by ensuring vacuum integrity;
Quality manufacture ensures standardized tube with uniformity and reproducibility;
