 "summary": "Dry coolers, adiabatic/evaporative units, and cooling towers reject heat picked up by the facility water loop to outside air, driven by fans and motors.",
 "description_md": "This equipment sits at the end of the facility cooling chain, rejecting heat that chillers (6.01) concentrated or, in free-cooling designs, heat drawn straight off the facility water loop (6.05). The choice among dry (air-only), adiabatic (evaporative-assisted), and wet cooling-tower designs trades water consumption against fan energy and footprint, a tradeoff drawing more scrutiny as campuses grow and site water rights come under pressure — see water treatment and reuse (6.06). AI campuses' round-the-clock, weather-insensitive load makes free-cooling hours more valuable than in a conventional building, pushing designs toward larger dry-cooler and adiabatic arrays that can carry more of the year without compressors. Fans and motors are a distinct, high-count sub-component here, sized for continuous duty and increasingly specified with variable-speed drives for part-load efficiency. Investors should track cooling-tower and dry-cooler capacity backlogs alongside chillers, and the split between water-intensive and water-free designs on new campuses, since that choice reshapes both the bill of materials and the number of large fans a given site needs.",
 "ai_delta": "Round-the-clock AI load raises the number of full-load hours this equipment runs and makes water-free or low-water dry and adiabatic designs more valuable at sites where water rights or drought risk constrain wet cooling towers.",
