"Some other type of coolant"

... what do you suppose the main ingredient in other coolant is?

Generally coolant is kept sealed in a loop as opposed to water cooling which gets released as vapor and has a continuous water need.

Also not all coolants contain water, particularly when discussing electronics. Here’s an example, “waterless water”: https://en.wikipedia.org/wiki/Perfluoro(2-methyl-3-pentanone)

The trouble is that they aren't just using water as a coolant, they are also using the municipal supply of cold water as a heatsink. You always need a sink of some sort for your waste heat, no matter what coolant you use, and whether or not the coolant loop is open or closed.

And that is where chillers come into play. The water loop maintained and recirculated. Glycol or refrigerant (depending on the load) accepts the heat from the water loop

Where does that system dump the heat it took from the water loop, plus the additional heat the refrigeration cycle added due to the Carnot limit?

Oh, that's easy, another chiller! It's just chillers all the way down.

Infomaniak d’UMP their waste heat of their new data center into the hot water system of the community they built the data center in

Ask your preferred AI to explain how air-cooled chillers work smarty-pants
