Energy conservation thanks to efficient water cooling
The temperature of the water is one of the key factors in the process of snow-making. Using water at the ideal temperature improves the performance of the individual snow guns. TechnoAlpin has therefore designed its own cooling towers for use with our snow-making systems. The cooling towers in the "Cooltech" range have a honeycomb-type cooling system which works by redirecting the water. All the components are designed for extreme working conditions and can withstand high pressures. The cooling of the water has a positive impact on the snow output and therefore on the energy consumption of the snow guns. Each snow gun can produce 45% more snow on average if supplied with water at the right temperature. This means 45% more output with little change in energy consumption. Moreover, the snow-making process can begin earlier if a water cooling system is installed. This translates into an enormous commercial advantage for the ski resort.
The cooling towers have been in use this year in Gerlitzen (AUT). Two towers, each boasting a throughput of 90 l/s, have been installed in the Carinthia ski resort. The water is delivered to the cooling tower at a temperature of 9.3 °C. The temperature of the water at the output is 2°C – corresponding to a cooling capacity of 2,732 kW per tower. Thanks to the ingenious honeycomb-type system, this cooling capacity can be achieved with very low energy consumption. The two towers consume 90 kW in total which corresponds to 1.6% of the cooling capacity actually achieved. Thanks to the increased snow output, the cooling towers are bringing about a significant reduction in energy consumption in Gerlitzen. Taking account of the total energy consumption of the Gerlitzen system, consisting of snow guns, pumping plants and cooling towers, the higher snow output leads to a cost saving of 25%.
