The horizontal devices have a rectangular shape, the air is blown by the axial axial fan (similar to a squirrel wheel) through the column-shaped heating spiral system placed in several rows one behind the other. In stationary devices, a radial fan (the same as conventional fans) moves the air through a concentric heating coil system along a circular arc.
