Product Specifications / Features

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>0.93 (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;
Private Logo accepted.
