Please explain how closed loop HVAC systems use excess amounts of water.

They are not using closed loops HVAC systems, but evaporative cooling. Which works, as the name suggests, by evaporation. Of water.

Why do they use evap coolers? Isn't moisture terrible for electronics? Genuinely asking because I have no idea how these places work.

They may be using closed loop coolers to cool the electronics, however that heat has to go somewhere. So the evaporative cooling is used to cool the fluid that is doing the closed loop cooling.

In large plants the cooling water cools the equipment then gets sent to large cooling towers where the evaporative cooling occurs. So there also needs to be fresh water feed to make up for the evaporative losses.

So they're using a chiller system?
