Glass Evacuated Solar Collector Tube

 Glass Evacuated Solar Collector TubeDetailed Product Description 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 coatingis sputtered, the jacket between the two glass tubes are evacucated to extremely low vacuum to reduce the heatloss by free convection and conduction. Top quality tubes increase the solar yield of your solar system and reducethe aging problem.This technology can be utilized under all kinds of climate conditions, especially better in colder area.FeaturesHigh absorptance a>0.93 (AM1.5) and low emittance e<0.06 (80 Celcius degree);Borosilicate glass 3.3 with transmittance higher than 91%Long service life by ensuring vacuum integrity;Quality manufacture ensures standadized tube with uniformity and reproducibility;
