The striking feature is the wide, clean strip below the copper-edged chimney. We achieve the same effect with our copper strips between the heat exchangers. The possible impacts of the very small quantity of copper on the sewage treatment plants have been investigated by leading energy service providers, public utilities and wastewater associations: The anti-fouling system is absolutely harmless for sewage treatment plants. Measurement results available on request.

So heat exchangers do not have to be slimey and insulating. They have to conduct heat well. With a lot of time and money a new ferritic steel was developed which makes it at least as suitable for withstanding corrosion and erosion as the previously used material. In addition, it was possible to increase the thermal conductivity by over 80%.
