Due to the cold weather, the icing that exists on the train must be removed regularly to prevent damage or lumps of ice causing malfunctions in the safety system.

A row of 40 Mark Föhn air heaters blowing high-pressure air of 60 degrees to the trains, making sure they defrost rapidly. Now the trains can leave the de-frosting station in less than 45 minutes. This to the satisfaction of the railway company.
The delivery consisted of: 40 gas fired air heaters type Mark Föhn 270 with an air displacement of 20.000 m3/h and a nominal power of 280 kW. The available external static pressure is 500 Pascal.
