With the solar air collectors, a simple and very efficient way has subsequently a solar heater in an existing building to install. Cold and moist air is replaced by dry warmth. Power from the built-in solar cell powers a fan that fresh, filtered outside air draws in the collector. There the air is heated by sunshine depending on up to 40C ° above the outside temperature. Subsequently, the cozy, warm air is directed through air ducts in the interior and led the stale humid air outside. Everything is coordinated, so that the system is fully automatic and safely during your absence. The twin solar air collector was developed in collaboration with the Fraunhofer Institute for Solar technology and has performed in independent tests as the test winner. The high quality and over 25 years experience of the manufacturer, the sun is optimally utilized and converted about 70% of incident solar radiation into heat. Year after year, the plant operates at no additional cost, the air filter is the only element that needs to be cleaned from time to time. Since the installation is very simple and the ventilation pipes are available in any hardware store is a DIY problem.

Operating principle see picture at the bottom, detailed information in the PDF files to download, other collector sizes on request.
