Together with our customer Wintertechnik Engineering, we implemented the first stage of the planned expansion of the artificial snow machines at the “Einhornbahn” pump station in Bürserberg at the end of October 2009.
We were responsible for the entire control system for the artificial snow machines from engineering right through to the successful implementation of the system.

The control of guaranteed snow
Artificial snow machines only run for a few days every year but when they are in operation, they work at an intense rate and must be free of interference factors. The plant was therefore designed in such a way that, in the case of disruption to the control terminal or system, an emergency backup system (controlled by a switch/button) could be activated to ensure uninterrupted snow production.
In the pump station, two booster pumps are responsible for ensuring plant pressure. Two primary pumps which are controlled using a frequency inverter guarantee the required snow pressure for the snow cannons for wherever they are on the slopes.
A 15” touch panel display with a WinCC visualisation application ensures comfortable operation. The entire plant is controlled using a Siemens Simatic S7 control system with decentralised Profibus I/Os. In addition, the entire system can be controlled and monitored by snow technicians via a central control and communication system.
Ensuring that Austria continues to be one of the most popular international skiing destinations simply can’t be left to chance.
