The economy of the ski and mountain industry is dependent on the randomness and unreliability of snowfall. Ski resorts must counteract the lack of natural snow to guarantee that they can open during the busiest tourist seasons. Snow making machines currently available in the market are both costly economically and for the environment. We resolve these issues by offering a clean-tech snowmaking machine, producing snow of the highest quality. Furthermore, our machine can operate in temperatures above 0°C and therefore it produces snow even when traditional snowmakers (fans and cannons) cannot. The proprietary technology is based on a steam jet ejector chiller (SJEC) and uses the triple point of water. The thermal energy for the ejector can be provided by solar collectors or by a biomass steam boiler. Water is the only working fluid in the entire refrigeration system as there are no chemical additives, which guarantees an ecologically friendly concept for the snow supply. Thermal energy for the machine is provided by renewable energy sources, which may be either a solar thermal collector or a biomass steam boiler.
