Descripción del producto

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 evacucated 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 absorptance a>0.*3 (AM1.5) and low emittance e<0.*6 (*0 Celcius degree); Borosilicate glass 3.3 with transmittance higher than *1% Long service life by ensuring vacuum integrity; Quality manufacture ensures standadized tube with uniformity and reproducibility; Private Logo accepted. for more information please visit our page www dot cibsolar dot com. or send us email to info at cibsolar dot com.
