I go into a lot of data centers. Most large ones will use cold water sources with some kind of backup system. The backup is usually only rated for a short time and does not have the capacity to replace the chilled water.

Understood, but are those closed-loop recirculating systems, or open systems with a lot of evaporative loss?

The ones like this that use chilled water are open systems which require a steady supply of chilled water from an outside source.

They can operate a short time without it on the backup systems they are supposed to have. The backup systems are expensive and rarely rated for long term use.

Good for Utah. This datacenter brings a lot of money into the state so this is an encouraging move by politicians.
