Product Description

At the heart of each vacuum tube lies a sophisticated U pipe, featuring direct flow-through connectivity, seamlessly linked to the
header pipe nestled within the manifold. This expertly engineered U pipe is encapsulated in an aluminum heat transfer fin, ensuring
optimal heat transmission from the vacuum tube's interior directly to the U pipe, maximizing efficiency.
Sunlight effortlessly permeates the outer glass tube and is superbly harnessed on the exterior of the inner glass tube by
a cutting-edge, highly selective sputter layer. This captured solar energy is efficiently channeled to a flush-contact
aluminum shield, and subsequently to a copper pipe infused with a dynamic heat transfer fluid. The 360° aluminum heat
transfer fin guarantees unparalleled speed in energy transmission.
