Product Description

Nestled within each state-of-the-art vacuum tube, you'll find a cutting-edge U pipe, designed with a seamless direct flow-through connection that effortlessly links to the
header pipe within the manifold. This U pipe is precision-engineered, elegantly seamed in an aluminum heat transfer fin located
inside the vacuum tube, expertly channeling heat from the tube's interior directly to the U pipe, ensuring optimal thermal efficiency.
Solar radiation elegantly penetrates the outer layer of the glass tube, and upon reaching the inner glass tube, it is astutely captured by
a highly selective sputter layer. This ingenious layer ensures that the solar energy is expertly transmitted to a flush-contact
aluminum shield. From there, the energy is transferred to a copper pipe filled with a specialized heat transfer fluid. The comprehensive 360° aluminum heat
transfer fin guarantees a swift and efficient energy transfer, optimizing performance.
