Alanod-SolarEFFICIENCY. SOLAR. SURFACES.

Surface treatment par excellenceAs a subsidiary of ALANOD GmbH & Co KG, Alanod-Solar benefi ts from more than 30 years of experience in the production of surface fi nished aluminium and copper strips. This expertise enables Alanod-Solar to focus with its products on the environmentally friendly generation of solar energy.

On four vacuum coating lines (PVD), and a lacquering line, specially devel-oped for Sol-Gel processes, selective absorbing or highly refl ective coat-ing systems are produced in a coil-to-coil process. An existing global sales network ensures tailor-made, on-site advice and support. Whichever world wide market you are in, we have on hand the resourcesand logistics to look after your specifi c needs.

Solar refl ectionWith our refl ecting surfaces, we offer various materials with a total solar refl ectance ranging between 85% and 95%. Thanks to a weather-resistant nano-composite lay-er, MIRO-SUN® is an ideal material for outdoor applica-tions. This is used as CPC refl ectors (CPC= Compound Parabolic Concentrator) in evacuated tube collectors and parabolic trough concentrators (CSP = Concentrated So-lar Power). In addition, MIRO-SUN® can also be used as a concentrating refl ector material for photovoltaic ap-plications (CPV = Concentrated Photovoltaics). The dif-ferent products in the portfolio enables Alanod-Solar to offer an ideal component for every possible application.

Solar absorptioneta plus®, mirotherm® and mirosol® TS are the three selective absorber coating systems for solar collectors. eta plus® and mirotherm® coatings are continuously produced in a PVD-process. This achieves 95% ab-sorption and at the same time, a low emission of not

more than 5%. For the fi rst time we offer, with mirosol® TS, a coil coated selective absorp-

tive lacquer.All the absorbing products are used in

a diverse range of solar-thermal col-lectors. Mostly copper or aluminium tubes are welded to the rear side of the absorbers to conduct heat, whereby laser welding has be-come established as the optimum

technology for joining together both identical and dissimilar metals. This

method ensures that the joints achieve not only long-term mechanical stability

but also excellent thermal conductivity.

Global playerOur top quality products are sold, processed and in-stalled by our partner companies on all fi ve continents. We are the world’s fi rst company to have reached the milestone of having sold more than 21 million square metres of absorber surface area.

Furthermore, we have an integrated and certifi ed qual-ity and environmental management system according to EN ISO 9001/14001 and also an energy management system certifi ed to ISO 50001.

eta plus® and mirotherm®

Technical informationmirosol® TS

Consists of an aluminium or copper strip 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 refl ecting layer ensures low thermal emission (ε), the metal oxide absorption and antirefl ection layers ensure highest solar absorption (α) while offering resis-tance against outside agents.

For the fi rst time, besides PVD coatings, selective lacquer is available for solar thermal applications. mirosol TS is a selective lacquer applied in a specially developed pro-cess on aluminium. The selective lacquer is hydrophob and resistant to fi ngerprints.

MIRO-SUN®

Technical information

Based on our MIRO®-product range which produces approx. 95% total light refl ection we have developed MIRO-SUN® especially for outdoor applications.A continuous air-to-air PVD-process applies a super-refl ec-

tive layer (MIRO®) to coil anodized material and after-wards the surface (MIRO-SUN®) is protected by a Nano-Composite in a coil-coating process.
