Heat exchangers EC 20 in HDR

Three heatexchangers at unit EC 20, each with a capacity of 50%, so normally always two in use.
The white piping is sweetwater (demineralized) and the green pipes carry the seawater.
At the moment we have some temporary piping ; just to cool down the system used by the gasturbine. The unit is in preservation, so the gasturbine is only used for special occasions, when there is shortage on the grid.
