sunselect®

Selectively absorbing copper strip for solar collectors

Applications:
  • Flat-plate collectors
  • Vacuum tube collectors


  • Construction:
    Consists of a copper strip, onto which in a world-wide unique air-to-air process, a system of three layers is applied using the physical vapour deposition technique.
    While the infrared reflecting substrate ensures low thermal emission (ε), the metal oxide layers for absorption and anti reflection ensure highest solar absorption (α) while additionally offering resistance against outside agents.

    Sizes:
    Material width: up to 1200 mm (mill`s limit)
    Material thickness: 0.1 - 0.5 mm

    Available in:
    Slit coil or sheets with protective tape or paper
    interleaving upon request.

    Optical values:
    Solar absorption: (AM 1.5)
    αsol = 0.95 ± 0.02

    Thermal emission (at 100°C)
    ε(100°C) = 0.05± 0.02
