The super vacuum tubes adopts special material,it is different to the common.Thesuper vacuum tubes make the heating area to small part, as you can see on the picture, it is the little pipe out of the dark one. The absorbing pipe is all closed,the
solar energy passes to the heating part with special medium.The temperature
of the heating part is very high because of the energy focusing on one part,
it raises the speed of heating. It adopts the advanced skill of interfering thin
coating, too.
Diameter of pipe: dia. 47mm, dia. 58mm, dia. 70mm
Length of pipe:1.2m,1.5m,1.6m,1.7m,1.8m,1.9m,2.0m,2.1m,2.2m
