Every TechnoAlpin snow gun is subjected to a functional check with water before delivery to ensure the quality of the snow gun, regardless of whether it is new or used.
The test stands have a water tank that collects and reuses water. Before use, the water is treated with UV light to kill any bacteria, ensuring it can be used over a long time frame. This test water recirculation system enabled TechnoAlpin to save around 5,800 m³ of water per year in 2021-22 and around 8,626 m³ per year in 2022-23.
These tests require high-pressure water, which is provided by an internal pumping station at both sites. The previous system was optimized in 2023. Up until that point, the pressure of the system was kept at a constant level, regardless of whether tests were being performed. This required a significant amount of energy, namely 20.5 kWh per m³ of water. With the new system, the pumps activate automatically when the snow guns are tested. The amount of energy required has therefore been reduced to just 3.7 kWh per m³ of water.
