Evidence
QDs should benefit most, alongside manifolds and cold plates, with CDUs also benefiting, though to a lesser extent
Context After
For the FWS layout, the headline implication is the potential for chiller-less designs. While we addressed this debate in a separate explanatory note for our core research and datacenter model subscribers, we reiterate that this is not entirely disruptive. Some operators are already running Blackwell systems without chillers in more AI-optimized designs, while others choose to retain chillers for workload flexibility, mixed-hall compatibility, redundancy, and reliability. Over the long term, we expect AI-optimized systems to make chillers less necessary, with content shifting from air-cooled chillers toward dry coolers or adiabatic towers. We currently estimate roughly 0.2M/MW for dry coolers or adiabatic towers. SPX Technologies, alongside BAC and Evapco, could benefit, while Johnson Controls, Carrier, and Trane may be challenged. Nonetheless, we expect this efficiency/flexibility trade-off to persist in the medium term and do not foresee a chiller downturn occurring overnight. See our Industrials Model for more details. ↗
