New Energy-efficient Snowgun System

The New Energy-efficient Snowgun System NESSy combines the latest scientific knowledge with well-established snowmaking technology.

• 80% less air pressure than comparable lances
• Up to 2°C higher snow making start temperetatures (marginal temp.)
• Higher water temperatures has less of an effect
• Low noise emissions
• No additives required

This innovative snowgun is awarded by Swiss Excellence and is the result of 3 years intense research and development and joint collaboration between the Institute for Thermo- and Fluid-Engineering ITFE, University of Applied Sciences Northwestern Switzerland, Swiss Federal Institute for Snow and Avalanche Research SLF, Davos, MVT micro technologies AG, nozzle technology, and BÄCHLER TOP TRACK AG, snowmaking technology. This project was supported by the Innovation Promotion Agency (CTI) of the Swiss Federal Office for Professional Education and Technology (OPET).

Through field tests in a climate controlled wind tunnel with a detailed theoretical model numerous breakthroughs could be achieved and then optimized. The results of the breakthrough snow lance is a drastic reduction of the required air pressure, snow making at a 2 °C higher temperature and snow performance is affected less by higher water temperatures. Through improved nozzle technology and the reduced air pressure NESSy produces very low noise emissions.
