Solar radiation is absorbed by the collector, which in turn warms its surface The heat from the collector surface is transferred to the boundary layer of air

Fan unit Ambient air


From the air cavity, the heated fresh air can then be delivered directly into the building or as preheated air to the building’s main heating plant.


warmed by sun and drawn in through perforations
