This type uses the all-glass evacuated tube solar collectors as the heat-absorbing element. The high vacuum degree of the clearance between the outer and inner tube reduces the heat emission, which is caused by convection and conduction. The layer films (coating) of the all-glass evacuated tubes transfer the sun energy into heat energy. The high absorption and low emittance rate of Sunray’s layer films is unique.
The manifold is made of stainless steel. The header is a pair of contoured copper pipes with dry connect sockets that the evacuated tubes plug into. The manifold casing is made of a strong but lightweight stainless steel that is folded to form a strong protective enclose. In addition the glass wool insulation is literally baked like a cake to form a complete structural shell around the header pipe.
The mounting is easy to install with various options and settings according to different mounting methods.
