unglazed perforated plate collector
The most common application of this collector is for building ventilation air heating. Other possible components for this system are: a 20–30 cm air gap between the building, a canopy at the top of the wall that acts as a distribution manifold, and by-pass dampers so that air will by-pass the system during warm weather.
Another application for the perforated plate collector collector is crop drying. Systems have been installed in South America and Asia for drying of tea, coffee beans, and tobacco.
