They absolutely can run closed loop. It does not cool as well as evaporative cooling (it takes MASSIVE heat to evaporate water) but it can work if designed right with large system capacity and big radiators. Trouble is it’s likely more expensive than pissing away the water and we know all that matters is bottom line.
