About this update from Ecolab Inc.
Ecolab today announced the close of its acquisition of CoolIT Systems, a leader in direct liquid cooling for high‑density data centers. The transaction closed earlier than expected, and Ecolab welcomes the world-class CoolIT team to the company. Ecolab acquired CoolIT for approximately $4.75 billion. CoolIT’s year‑to‑date sales have grown more than 100%, driven by accelerating demand for liquid cooling in AI data centers. With CoolIT, Ecolab extends its established global leadership in water technologies, research and service to the fastest-growing market in the world: AI infrastructure and computing. At the heart of AI is water. We need water to produce chips, power chips, and cool chips. Ecolab is now uniquely positioned to offer end-to-end solutions across the full AI value chain, from ultra-pure water to produce the most advanced chips, to high-performing water systems for optimized power generation, to direct liquid cooling for the most powerful AI data centers. This enables Ecolab to help customers scale AI faster with global solutions that protect people, natural resources, and communities. At Supercomputing in November 2026 in Chicago, Ecolab plans to introduce a breakthrough innovation: a new end-to-end 3D TRASAR™ cooling platform combining CoolIT technologies, including cooling distribution units and high-performing cold plates, with integrated 3D TRASAR™ digital optimization and advanced cooling fluids. Supported by global expertise, it will optimize water, power, and compute performance at scale. This will provide operators with real‑time visibility into system performance to help reduce cooling power demand and increase power efficiency, while leveraging closed-loop solutions to move data centers toward a near-zero water footprint. This technology is applicable for AI architectures like NVIDIA Vera Rubin, Grace Blackwell, and more to help enhance uptime while accelerating the shift to an AI infrastructure with less impact on the environment and natural resources. “NVIDIA has collaborated with Ecolab and CoolIT across a broad range of liquid‑cooling initiatives, including coolant qualification, coolant health monitoring, cooling infrastructure development, and next‑generation AI factory technologies,” said Ali Heydari, technical director and distinguished engineer at NVIDIA, and Saket Karajgikar, senior engineering manager and ASME fellow at N...
