"Schneider: hotter coolant cuts AI datacenter water use" — The Register · AI & Technology
Schneider Electric, a major data center infrastructure vendor, is claiming that running liquid at higher temperatures in AI data centers can significantly cut water consumption. The idea is that warmer coolant allows for more hours of 'free cooling' (using outside air or water-side economizers instead of energy- and water-intensive chillers and evaporative cooling towers), potentially halving water use at a 100 MW facility in hot climates. This is a technical efficiency pitch aimed at operators facing water scarcity and regulatory pressure, not a new product launch per se.
The claim is a corporate statement from Schneider Electric, reported by The Register (an aggregated/secondary source with no primary citation in the item). The underlying physics is well-established — higher coolant temperatures enable more economizer hours — and the search results corroborate that Schneider has been promoting and water-reduction strategies. However, the specific 'at least half' figure is Schneider's own estimate, not an independent measurement, and the reporting likely relies on a press release or briefing rather than a peer-reviewed study.
This is genuinely new reporting from September 21, 2026, reflecting Schneider's current statements; no recirculation year is indicated.
We covered Schneider Electric's broader push into liquid cooling for AI in September 2025, when it unveiled a portfolio with Motivair for high-performance computing workloads, and in September 2026 we noted direct liquid cooling deployment risks in AI data centers.
