SolarVenti air collector – heating fresh air by using solar energy

CTCN Keyword Matches

SolarVenti has produced solar air collectors for different purposes for more than 25 years. In 2015 the number of sold collectors is near to 70.000 units.

The air collectors have a unique way of heating fresh air – running for free by solar energy. The air collectors heats and dehumidificates houses, basements or other buildings having humidity problems.

When heating the air you lower the relative humidity, and this may be used for drying and making a better indoor climate.  The small systems even run for free using a solar driven fan.

SolarVenti has much experience in all climate zones on earth – from Greenland to Australia – and we have large professional systems available. These are used in industrial buildings for drying purposes such as drying of grain, fish, coffe etc. or just for renewing the air with fresh warm air – saving much heating energy. SolarVenti has also been proven as the perfect solution for keeping halls with mashinery dry and free of rust on metal.

SolarVenti cooperates with:  Technical University of Denmark (DTU), DtI, Agrotech, Ecolab, Technical Scool in Hadsten, TU München, Fraunhofer Inst. and many others. Our systems are Solar Keymarked.

Payback time is often as low as 2 years, due to the efficient function. And its much more than just an energy saving device. It gives a lot of nice comfort on top.
