EURO C20 AR

The EURO C20 AR featuring Sunarc solar glass with anti reflection nano technology is one of Europe’s most efficient flat plate collectors. It is generously dimensioned with a 2.4 m² effective aperture area. It surpasses therewith many other competing standard-format collectors. Moreover, the gross area, which is relevant for most regional subsidies is 2.6 m². It can be installed in horizontal or vertical format and is applicable for on-roof, in-roof and for flat roof (free standing) mountings. Its top-grade performance and versatility make it one of the most sought after sun catchers in the market today.

The glass: Antireflection glass increases energy yield
The glass covers of the EURO HTF C20 collectors with their highly pure glass mixture allow much of the solar radiation to pass – 91%.
Now we have come yet another step further: a special surface treatment process increases the transmissivity to 96%! The EURO C-20 AR with its new Sunarc® anti-reflection glass brings up to 10% more power!

The Absorber: Highly selective for optimized solar yield
Highly selective absorber coatings trap solar heat optimally and minimize back scattering of the absorbed heat. In our new ultrasonic welding facility, we convert these high quality absorber sheets to surface absorbers. The continuous surface, as distinct from the strip absorbers, further reduces heat loss.

The encasing: all round insulation for minimized heat loss
The 60 mm thick thermal insulation on the back side and continuous frame insulation reduces heat losses and ensures high temperatures. In stagnation, Wagner & Co collectors achieve temperatures of up to 232 °C!

High technology solar collectors
The test report of the Solar Institue in Hameln delivers proof: the EURO C20 AR Solar Collector is Germany’s most efficient flat plate collector with a peak yield of 546 kWh/m per year (according to ITW standard 5m²) and hence also one of the most powerful collectors in Europe.
