Snow uncertainty is a critical factor for winter tourism. With the KTI snowPRO technology, we have created new opportunities for a ski resort in Sauerland, Germany, in that the season can now be planned and snow is guaranteed. In addition to the first installation in 2014, seven other lifts followed in the region, which were equipped with the technology from KTI snowPRO are equipped.  Already in 2014 we are equipping from KTI snowPRO a region in the Sauerland region with a system for snowmaking at plus degrees. The uncertain weather and fluctuating temperatures played an increasingly important role in the issue of snow reliability when it came to planning the opening of the ski resort. Due to its location, the popular ski resort attracts German winter sports enthusiasts but also English, Dutch and Danish skiers. Four years later, in 2018, followed another installation of two lifts of type snowPRO210 and already in 2019 another two of the same design. With a total of six systems, the winter sports resort can now speak of real snow reliability. All of the installed systems generate flake ice, which is transformed into snow by a mechanical process. In 2020, the first system of the type snowPRO260 installed. With plate ice as a real alternative to flake ice, the success story of this technology, which is extremely energy-efficient and effective for snowmaking at plus degrees, begins here. In 2022, another of the same type followed in order to continue to guarantee snow reliability for winter sports enthusiasts and to ensure plannability for the important economic sector of tourism.
