The system was put into operation at the Italian resort on schedule at the end of October/beginning of November, with a team from TechnoAlpin handing over the turnkey system more than two weeks before the requested completion date.
TR8 fan guns were installed up to a height of 3320 m. The TR8’s fan and compressor are driven by just one electric motor, a first. The compressor is an oil-free rotary screw compressor, which stands out due to its uniform compressed air outlet, its lower weight and easy maintenance. Thanks to its permanent magnet motor with inverter, the TR8 also achieves IE4 mechanical efficiency. In contrast to the T40, the TR8 can therefore be operated in a much wider voltage range with no change in power consumption. It can be operated constantly at maximum motor efficiency and has a higher air output because of the improved efficiency.
