AdsoluteZero Turns Warm AI-Rack Water Into Cooling

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.
