Within each highly efficient vacuum tube lies an advanced U pipe designed for seamless direct flow-through, seamlessly integrated with the
header pipe housed within the sophisticated manifold. This U pipe is expertly seamed within an aluminum heat transfer fin, a marvel of engineering, located in the
interior of the vacuum tube. This design facilitates the efficient transmission of heat from the interior tube directly to the U pipe.
Solar radiation effortlessly permeates the outer glass tube, capturing abundant energy right at the exterior of the inner glass tube, thanks to a
highly selective sputter layer. This captured solar energy is efficiently transferred to a precision-engineered flush-contact
aluminum shield, subsequently channeling it to a copper pipe, ingeniously filled with cutting-edge heat transfer fluid. The 360° aluminum heat
transfer fin ensures the swiftest and most efficient energy transfer, maximizing performance.
