Ecolab IncEcolab acquires CoolIT Systems for $4.75B, gaining advanced liquid cooling technology for AI data centers.

Ecolab agreed on March 20, 2026, to acquire CoolIT Systems for approximately $4.75 billion in cash. On June 1, 2026, CoolIT announced it had developed a 15-kilowatt coldplate design for single-phase direct liquid cooling, delivering nearly four times the capacity of its previously demonstrated coldplate and extending its roadmap for future ultra-high-density AI infrastructure. The coldplate was validated using a standard water-glycol coolant at 1.2 liters per minute per kilowatt, with system-level performance suitable for 45-degree-Celsius warm-water cooling environments. The technology supports water-efficient AI infrastructure as higher-density GPUs and accelerators push data centers toward liquid cooling systems that move heat through engineered fluid loops instead of relying only on traditional air cooling.
