Krvavec ski resort has a complex system for snowmaking process. Geographic position, climate with rapid changes in temperatures, wind directions and weather conditions lead the necessity of snowmaking optimization. The ATASSplus software developed by TechnoAlpin is a product that best meets our expectations. The system itself manages snowmaking procedures using input data (outside temperature, humidity, wind, snow depth, snow gun condition, water flow, etc.) and is user friendly. Results: 30% less water needed to cover the slopes with technical snow; 40% less working hours, safe management (from the office); optimal snow depth on the slopes; less snow groomer hours; 30% electrical power reduction.
