The tried and trusted bestseller worldwide - mirotherm®

mirotherm® is the first commercially available solar selective absorber layer on an aluminium substrate produced with PVD-technology. It is the bestselling surface worldwide as more than 21 million m2 have been sold in the last 20 years. While the IR-reflecting layer ensures a low thermal emissivity, the oxide-absorption layer, in combination with an anti-reflection layer, ensures maximum solar absorption and resistance to external influences.

The all-rounder - eta plus®

eta plus®eta plus® achieves a very high solar absorption of 96 % - combined with a very low thermal emissivity of only 4 %. The product is available on copper or aluminium strip. is our fully sputtered product for solar thermal applications. It can be used in flat-plate collectors with full-surface or strip absorbers, in tube collectors as well as in air and large-area facade collectors.

Our lacquer product – mirosol® TS

In addition to PVD-coatings, coil-coated paints are also available for solar thermal collectors. mirosol® TS is ideal for solar thermal systems installed in regions with high solar radiation. In the production of mirosol® TS, a lacquer made of inorganic pigments functionalised with aminosilane is applied to aluminium. A specially developed coating process is used for this purpose.

mirosol® TS offers high resistance to heavy environmental pollution, salty air, moisture, condensation, oil and dirt as well as low stagnation temperature.
