Within each sophisticated vacuum tube lies an innovative U pipe that ensures direct and efficient flow-through, seamlessly connecting to the header pipe inside the manifold.
This U pipe is expertly encased within an aluminum heat transfer fin, positioned inside the vacuum tube, ensuring optimal heat conduction from the inner tube to the U pipe.
Inside the vacuum tube, heat is efficiently transmitted from the interior tube directly to the U pipe, thanks to the precise engineering of the aluminum heat transfer fin.
Solar radiation effortlessly penetrates the outer glass tube, capturing the sun's energy on the outer surface of the inner glass tube.
A highly selective sputter layer captures this solar radiation, transferring it effectively with flush-contact technology.
The energy is then passed to a 360° aluminum shield and further to a copper pipe filled with heat transfer fluid, ensuring maximum energy yield.
The 360° aluminum heat transfer fin guarantees the quickest and most efficient transfer of energy.
