Editorial interest 78/100 Selection signal · not a rating of the site

AdsoluteZero presents adsorption chillers that use 45–65°C return water from liquid-cooled AI racks to produce chilled water without a compressor.

Landing page captured for the 2026-09-10 issue.

Field notes

The proposed system attaches to the secondary loop serving direct-liquid-cooled racks rather than replacing the rack cooling hardware. Warm return water regenerates alternating sorption beds; evaporation under vacuum then produces chilled water for recirculation, with dry-cooler rejection described as evaporation-free. The page targets 45–65°C returns from GB300-era systems and identifies a proprietary composite adsorbent with a modeled 4.2× water-uptake advantage. Commercial traction, including approximately $1 million in committed sales, is presented as a company claim.
