Abstract

The invention relates to a device (1) for prevention of scale in water supply systems with at least one electrode unit (12), mounted in a reaction vessel or housing on the device, through which water flows, whereby at least two layers of a water-permeable electrical conducting planar material are provided in the annular gap between electrode elements of the electrode unit (12). Each layer is electrically connected to an electrode element. A separating intermediate layer made from a water-permeable electrical insulating planar material is arranged between the above layers.
