Precision control software for efficient snowmaking operations

Fully automatic and intelligent control of the snowmaking system is the basic prerequisite for energy-efficient snow production. Only with the aid of powerful control software is it possible to exploit the ever shorter windows when the temperature is at its optimum for making snow or to react to changes in the most efficient way. In ATASSplus and Liberty, TechnoAlpin supplies advanced technology for the straightforward and precise control of snowmaking systems.


The ATASSplus software developed by TechnoAlpin collects data from snow guns and meteo stations, and optimizes the snow production according to the prevailing conditions. The use of resources is continuously monitored and analyzed, and a clever water and air management system enables a significant conservation of resources.

ATASSplus provides an overview of the temperature readings in the whole resort, allowing energy-efficient snow-making processes on individual ski slopes. The statistics in real time enable continual monitoring of the water and energy consumption and prevent the maximum power limit from being exceeded. The simple evaluation of the data facilitates exact and efficient planning of snow-making operations. It is also possible with ATASSplus to analyze data and react swiftly to changes in conditions. The ATASSplus SnowManager is also designed to display snow depth measurements in centimeters. This is an innovative feature in that the minimum snow quantities are defined and then the SnowManager automatically calculates the remaining amount of snow required for slopes. As soon as this limit is reached, the snow operations team is informed and the snow-making process can be stopped automatically by request. It is therefore possible, with the help of ATASSplus, to avoid the production of excess snow and to limit the amount to the level which is actually needed. This is the most economic, resource-efficient and eco-friendly way to run the system and to cover the whole length of the slope with snow of consistently high quality.

The TechnoAlpin software is continually updated and upgraded. The control of a snowmaking system has been further simplified by the 2016 ATASSplus update which boasts new unique features, an improved user interface, and an integrated maintenance manager for the whole system. A mobile app has also been developed for ATASSplus for even further simplification of snowmaking operations.

Weather module

Weather data are collected and analyzed professionally with the help of ATASSplus and they are combined with meteorological model data thanks to the collaboration with Europe's largest private weather service, MeteoGroup. This results in accurate and precise weather forecasts relevant to the use of snow guns, even when there are temperature differences in the ski resort. The weather can be forecast accurately for up to 10 days, serving as a decision-making aid for the efficient use of resources.



The Liberty control software developed by TechnoAlpin offers a simple, flexible and reliable means of controlling snowmaking systems. It can easily be integrated in the computer operating system and includes numerous applications for the control of the entire snowmaking system.

TechnoAlpin guarantees individual control and optimum use of the available resources with the use of Liberty. The software is suitable for all systems and can precisely control all the components and required resources. The resources and the production are adjusted to the weather conditions in real time, therefore energy efficiency is built into the use of the snowmaking system.

All the operating parameters are saved and are used to compile statistics and graphs in order to achieve optimum results in terms of snow coverage. Liberty enables a full overview of all the measurements taken on the slopes and in the machine room and, in conjunction with a remote maintenance system, it enables precise monitoring of the system.
