Abstract

The apparatus for making artificial snow by atomizing water comprises a ductlike housing mounted on a supporting frame, in which a blower is positioned and on whose downstream end a plurality of nozzles or orifices for spraying water or a water-air-mixture are provided. The ductlike housing is constructed double walled. An inner wall of the ductlike housing is provided with a plurality of holes. Sound absorbing material in the interior space located between the inner wall and an outer wall and one electric heater are also provided. Air baffles can also be provided which contain sound absorbing material and are similarly heated.
