Solar absorber coatings and surfaces
We manufacture a wide range of highly advanced absorption coatings, which are available on a choice of metal substrates. These offer unique combinations of thermal or solar energy absorption, with extremely low thermal emissivity.
Selective absorber coatings for aluminium or copper strips
eta plus® is our semi-finished product for solar thermal systems and is used in absorbers for flat-plate collectors with full-surface or strip absorbers, in tube collectors as well as in air and large-scale façade collectors. In addition, it facilitates the production of high-performance collectors for solar cooling and the generation of process heat.
eta plus® achieves a very high solar absorption of 96% – combined with a very low thermal emissivity of just 4%. Based upon an aluminium or copper strip, the innovative absorber layer system is applied using a continuous PVD method in a worldwide technologically unique air-vacuum-air process.
mirosol® TS is the ideal material for solar thermal systems installed in regions with high solar radiation. During the manufacture of mirosol® TS, a selective, hydrophobic lacquer is applied to aluminium in a specially developed process.
This means that for the first time, in addition to PVD coatings, lacquers using the coil coating method are now also available for solar thermal collectors.
mirosol® TS is unique thanks to its high resistance to heavy environmental pollution, salty air, moisture, condensation, oil and dirt as well as a low stagnation temperature.
Developed on the basis of our best-selling and established coating mirotherm®, mirotherm® Control offers all the advantages of the proven system: solar absorption up to 96%, highest product quality, resistance to external influences such as moisture and integrated protection against overheating.
With Government policies driving investment in all kinds of renewables, the efficacy of solar energy generation is rising to the top of many agendas, and is something of vital importance to profitability.
