This is the first natural draught cooling tower in Greece to be equipped with plastic fill. The water distribution system and the drift eliminator also consist of environment-friendly plastic and are therefore particularly resistant to corrosion.
Due to the extreme weather conditions in the mountains of Northern Greece in the winter the natural draught cooling tower is provided with a multi-sectional connection system for water distribution and a de-icing pipe.
These sections can be connected and disconnected locally or from the central control room. This ensures reliable winter operation and also facilitates maintenance and servicing of the cooling tower system.
