Abstract
A nucleation device associated with a spray head and operating by either internal mixing or external mixing. The ratio air/water is not less than 200 and the pressurized water is supplied by the spray head nozzles, which, by simple circulation of water, at the nucleation device, prevents freezing problems. The nucleation device includes a part in the shape of a spray tip for high speed spraying of compressed air and parts in the shape small diameter nozzles for spraying pressurized water into the air stream.
