Method of evaporating and/or drying of liquid-applied coating. Warm air is sucked in from workspace and/or from the outside, gets filtrated and warmed and is supplied selectively to the workpieces via air nozzles. The drying process itself is done inside of drying tunnels, flat-flow dryers, high dryers ... -dependent on geometry of the workpiece, production quantity, spatial conditions etc. ...

To speed up the drying process, hot-air dryers are combined with infrared-radiators, e. g. when using water-soluble lacquers.
