The water cooling system !

After the coolant comes back from underground with approx. 14 degrees Celsius it has to be re-cooled down to the required two degrees Celsius - and that happens in this water cooling system. Because of the fact that the three pumps have a capacity of 500 cubic metres of water per hour and pump, you can imagine that there is a lot of waste heat.

The waste heat is reduced in the water cooling system shown in this picture.
