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
  • Snow production start at -1.5° WBT
  • 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.

Main Features of NESSy?

The New Energy-efficient Snowgun System NESSy combines the latest scientific knowledge with well-established snowmaking technology. Several patents on the new nozzle technology are pending.

NESSy based on reliable Bächler snowmaking technology
  • Modular design
  • Single- or multi-stage water flow
  • High-quality nozzles from MVT micro technologies AG
  • Existing Bächler snowguns can be upgraded easily

Suitable supplies

SnoTek ET MEDUSA

The 8-level SnoTek ET MEDUSA can produce an enormous amount of snow of up to 124 m3/h at lower temperatures.

Pit Solutions

The ingenious pit components can be assembled on your demand. Thereby it provides endless opportunities to design the system inexpensive and user-optimised.

Combi-Pitvale

The very compact combi-pitvalve with combined control of water and air in the basic is perfectly suited for use with NESSy/SnoTek.

Hydrant handler

The handler is applicable for nearly all common hydrants through the exchange of the shaft adapter.

Compressor

The compact and quiet compressor, which is installed in a box of aluminium, feeds a NESSy or SnoTek with sufficient compressed air.

Snow and transport hoses

Our approved and high quality heavy-duty snow hose for low-pressure, high-pressure and lance-snowmaking-systems.

Base Frame Mobile

The installation of the base frame occurs before winter with a wheeled vehicle on the mounted wheels or with a snow groomer on the snow.

Slewing drive

The slewing drive is used for the optimal area width snowmaking.

Fully automatic system BTT

The fully automatic system, which is developed specifically for Bächler snowmakers, is characterised by the excellent adjustment with the optional components.
