Nozzles can be used with great advantage in rooms where long air throws are desirable, even at small air flows/volumes. Nozzles are suitable for both heating and cooling. Depending on the chosen nozzle the supplied air pattern can be adapted to the job at hand. Consequently, nozzles can be used to solve very different problems, but excells especially at ventilation of larger rooms with high ceilings. The nozzles can also be used as a “help-system” to lead heated air from units placed high up, down into the occupied zone.
