In technical snow-making, water is finely atomised using pressurised air and expelled from a snow gun in the form of droplets. On the way to the ground, the fog freezes into snow crystals before it lands.
As is the case with natural snowfall, with technical snow-making the air temperature and humidity must meet certain requirements. In technical snow-making we refer to the wet bulb temperature, in other words the relationship between the temperature and air humidity. Our snow machines are able to produce snow at a wet bulb temperature of -2.5 ºC. This means, with air humidity of 40% it is possible to produce artificial snow at a temperature of +1 ºC.
Where does the water for producing the snow actually come from?
Reservoirs are used for this. In spring and autumn they are filled from the stream. The amount of water that can be diverted from it is strictly regulated. These storage reservoirs are also used to irrigate the pasture. The fire service can also use them in the event of a fire. There is also room for fish in our reservoirs. They make sure that the water stays clean. Pumps are used to feed the water to the 100-plus snow machines in our ski resort.
The “snow masters” are responsible for ensuring that the technical snow-making machines run smoothly. During snow-making they check a range of parameters. If a machine is faulty, they are on the spot immediately to ensure that the breakdown lasts for as little time as possible.
Every year, an average of 250,000 kWh of electricity is needed to provide artificial snow for an area of 20 hectares.
A single flight from Munich to Mallorca and back with 200 passengers consumes exactly the same amount of energy.
In spring the artificial and natural snow melts and runs off in the form of water. The cycle begins again, and we are able to offer our guests perfect conditions on the slopes with guaranteed snow.
