AI Data Centers May Need Fewer Chillers—and More Precision from Mechanical and Controls Teams

Nvidia’s latest roadmap for high-density AI infrastructure is being read as a warning shot for traditional data center cooling—and for the service providers who build and maintain it.

In a recent LinkedIn analysis, industry veteran Tony Grayson points to Nvidia’s CES announcement that its upcoming platforms can operate with liquid cooling supply temperatures around 45 °C. At that temperature, many AI data centers could rely far less on conventional chilled-water plants and compressors, using dry coolers or other non-mechanical heat rejection for much of the year.

If adopted at scale, that shift could materially reduce energy use tied to cooling. Fewer compressor hours mean lower electrical demand, better PUE, and potentially smaller central plants. For owners building data centers, that opens the door to deferring or downsizing expensive chiller infrastructure.

For mechanical and controls service providers, this impacts scope. Warm-water liquid cooling puts far more pressure on pump reliability, flow control, leak detection, and water chemistry management. Commissioning tolerance tightens. Controls sequences become more mission-critical. Failure modes look different—and often harder to troubleshoot.

The “death of the chiller plant” framing is clearly aspirational. Even the article acknowledges that trim chillers or adiabatic assist will still be required in many climates and operating conditions. But the direction of travel is clear: less work centered on large centrifugal machines, more work in precision liquid handling and control.

Service firms that stay anchored to legacy chiller-centric scopes may find themselves exposed as AI workloads drive the next wave of data center builds.
