$ECL is reportedly moving to acquire CoolIT Systems for around $4.5B–$5B, a major push into data center liquid cooling. The deal shows how critical cooling tech has become as AI infrastructure scales and power demands surge. CoolIT specializes in advanced liquid cooling for high-performance computing, especially AI workloads. This move puts Ecolab right into the heart of the AI supply chain, not chips, but the infrastructure that keeps them running.
