Cooling that runs on the heat you throw away.
AI racks like the GB300 NVL72 dump enormous low-grade heat into their warm-water loops. AdsoluteZero turns that waste heat into cooling - adsorption chillers built on zeolite / calcium-chloride composites, with no compressor and near-zero evaporative water.
The name is the thesis: ADSorption to absolute zero.
For the first time, the heat source is the right temperature. Liquid-cooled AI racks return 45-65°C water - squarely inside the driving band adsorption chillers already use. AdsoluteZero is a drop-in module on the direct-liquid-cooling secondary loop: it takes the heat the CDU rejects and turns it back into cold. We complement liquid cooling - we don't replace it.
A materials advantage, packaged for the rack.
DC-tuned composite adsorbent
A zeolite / calcium-chloride composite engineered to regenerate at warm-water DLC temperatures - more water per gram at lower drive heat than plain zeolite. The material is the moat, and it's licensable.
Water-lean by design
Evaporation-free cooling for water-stressed regions - the sharpest wedge where cooling towers face permits, drought and community pushback.
Closes the loop on-site
Unlike district-heat reuse, which needs an offtaker and only displaces heating, cooling is always needed on-site, year-round. No external customer required.
Thermal storage built in
Sorption beds charge off-peak and release cooling on demand - a grid peak-shaving asset as AI strains interconnection queues.
Operators cooling dense AI - especially where water is scarce.
Hyperscale and neocloud operators running liquid-cooled GB300-class fleets, colocation providers under water and PUE pressure, and greenfield AI campuses in hot or water-stressed regions where evaporative cooling is a liability rather than an option.
Cool the AI build-out on its own exhaust.
