Four men and an extra valve....

We did a modification at the cooling system of the gasturbine of unit EC20.
The gasturbine is used as backup when shortage on the grid occusrs.
Before we used large firehoses, connected to the coolingsystem of unit EC 3 or 6 but we wanted a system that was easier to use and causes less sand on the floor of the basement.
There's a lot of sand in our coolingwater...
So now we use a part of the old EC 20 system and circulate it in a short circuit.
But we still need an extra valve and we had to talk about that...

Better in LARGE....
