TechnoAlpin:
The revolution at the summit
Only the world market leader is capable of coping with the most difficult installation conditions: one of the highest snow producers in Europe is installed at a height of 3320 m in Cervinia. The machine in question is the revolutionary TR8 fan gun. This snow producer is impressively unique because for the first time the fan and compressor are driven by just one electric motor. The compressor is an oil-free rotary screw compressor, which stands out due to its uniform compressed air outlet, its lower weight and easy maintenance. Thanks to its permanent magnet motor with inverter, the TR8 also achieves IE4 mechanical efficiency. In contrast to the T40, the TR8 can therefore be operated in a much wider voltage range than its predecessor with no change in power consumption. It can be operated constantly at maximum motor efficiency and has a higher air output because of the improved efficiency.
Understand Fan Guns:
Perhaps the most significant advantage that fan guns have over traditional air/water guns is that no air pipes need to be installed along ski trails. Although electrical cables must be run. Is that always 440v? However, on board air compressors are used. Is that used inject air into the water stream which shoots out the nozzles? That pressure, plus the fan gives the throw of water droplets.
Adjustment to weather conditions, especially temperature and humidity, are made through the air/water mix. Are traditional guns more flexible because they have a greater volume of air available to make adjustments?
Mt. Snow has gone big time into fan guns. I’ve not been to Crotched for over 25 yrs., but I understand they have also. Many areas have fans in wide open sections where the grater throw of fans can be well used. Are there other resorts that have significantly switched to fans?
