Ray Magic® NK
Ray Magic® NK (Naked) is a high performance hydronic radiant panel. It is installed within the ceiling (and walls) and it is covered with 5⁄8″ regular drywall, wood, or other ceiling material, to create unobstructed radiant surfaces.
The panel consists of a 1 1⁄2″ thick EPS board and aluminum heat transfer plates with propriety omega shaped channels. Pressed into these channels are two symmetrical 8 mm [≈ 5⁄16″] PE-RT radiant tubing circuits laid out in a serpentine pattern.
Each tubing circuit is connected in parallel to 16 mm [≈ 1⁄2″] PE-RT return and supply lines that run along the length of the panel.
Panels are connected together using patented slide-in fitting technology that allows for internal PE-RT piping expansion and contraction.
