Man made snow is made only by spraying a mix of air and water under pressure of into cool ambiant air. At the exit of the snow producer's nozzles, the mix of air and water is atomized. Micro-droplets form and cristalize during what is called the hang time and before touching the ground.

The R&D teams of MYNEIGE develop snowmaking equipment and products since 1976, based on air / water technology. MYNEIGE has acquired a significant expertise in the techniques of spraying and controlling the jet geometry, two key factors in the performance of a snow producer. The ranges of snow producers, Rubis, Borax and Safyr all benefit from this expertise and offer an optimal production.

The machine room houses the production and control components, pumping groups for the water, compressors for the air, automation panel and power cabinets. The machine room allows feeding the snow producers with air and water resources through the pipes system installed on the trails.

On the trail, regulating snowmaking valves and snow producers allow making snow, according to the local weather conditions. All weather data (temperature, humidity, wind etc.) are transmitted in real time to the snowmaking management software. The management software acts as the center piece of the system, It will give start-up orders to the components and equipment in the machine room. It will adjust in real time the air and water resources taking into consideration the evolution of the weather conditions; thus allowing respecting the operating parameter set by the operator and guaranteeing a best possible production.

MYNEIGE has developped all the materiel and equipment needed to run an automatic snowmaking system: The management software suite, Liberty, the snow producers, Rubis Evo, Borax and Safyr ranges, the snowmaking valves - YB and VAR, as well as its own PLC, the YPLC range, for the control of the machine rooms...

The measurement of wet bulb temperature takes into account several parameters:

• The temperature of the air
• The humidity of the air
• The barometric pressure

The combination of these three measures is used to determine the wet bulb temperature. Thus one can determine whether the conditions allow making snow, but also what the quantity and quality of snow production will be. The lower the wet bulb temperature is and the higher quantity and quality of snow of snow will be.

MYNEIGE has developed a calculation algorithm specifically tailored to manage a snowmaking system. In addition a special care is taken in the selection of temperature probes and humidity sensors. This ensures a high reliability of data transmission to the control software of the system, the Liberty sotware suite.

To improve the performance of a snow production facility, fisrt and foremost it is necessary to be able to know the different operating parameters on a long enough periode to have a relevant image ... A regular record of operating and production statistic and data allows building this history.

On the basis of the operating data, we can then make a diagnosis of energy performance (operation time, volume of water, air consumption) and suggest possible improvements to replace the existing snow producers by latest generation equipment, and make recommendation and new production practices (production quota) per trails or key sectors.

The teams of MYNEIGE have developped competences and tools to be able to conduct those energy and performance audits. In addition, the installations with a Liberty software suit benefit from a regular and detail record of the all operating parameters that are ready for use and analysis.

Equipment and materials developed by MYNEIGE incorporate the principle of upward compatibility. The old equipment is compatible with the new ones. This allows operators to be able to start from basic snowmaking solutions (manual or semi-automatic) and to up-grade their facilities toward more complex solutions.
