The condenser liquefies the steam coming out of the turbine and in this way enables a closed cycle.
To this end, the cooling water is passed through cooling towers where the energy absorbed in the condensation process is extracted. The cooling water circulates in a closed cycle with a quantity of about 2,100 cubic metres per hour.
The circulating cooling water is oxidised by means of ozonisation to keep it free from organic pollutants (pollen, algae etc.).
Moreover, hardness stabilisers to bind free hardness components and sulphuric acid for decarbonisation are added to the recooling water.
