Nozzles are the most important factor for good artificial snow. With the help of ultra-fine atomizing twin-fluid nozzles, smallest water drops are firstly produced, which immediately freeze to ice. In the next step, the drops of further single-fluid nozzles accumulate on this so-called ice germ over the flight time and become snowflakes. A perfect adaptation of compressed air and water pressure to the ambient temperatures is a prerequisite for good snow.
The throwing distance of up to 40 metres ensures that the snow is evenly distributed on the slopes. Depending on the snow gun, hollow cone or flat jet nozzles are used. With propeller machines – better known as snow cannons – hollow cone nozzles (e.g. series 214/216) are used. Flat jet nozzles (e.g. series 632) are used for snow-making lances.
