sunselect® and mirotherm®
Consists of an aluminium- or copperstrip which has been anodised on both sides; then in a world-wide unique air-to-air process, a system of three layers is applied using the physical vapour deposition technique (PVD).
While an infrared reflecting layer ensures low thermal emission (ε), the metal oxide absorption- and antireflection layers ensure highest solar absorption (α) while offering resistance against outside agents.
For the first time, besides PVD coatings, selective lacquer is available for solar thermal applications. mirosol TS is a selective lacquer applied in a special developed process on aluminium.
The selective lacquer is hydrophob and resistant to fingerprints.
