Ecolab Completes $4.75B CoolIT Buy to Enter AI Cooling Market

Ecolab has completed its $4.75 billion acquisition of CoolIT Systems, marking the water technology company's entry into the rapidly expanding market for AI data center cooling infrastructure. The deal closed ahead of schedule, according to Data Centre Magazine, which first reported the details.

The transaction positions Ecolab to address a critical bottleneck in AI deployment: the thermal management of high-density computing hardware. CoolIT brings direct-to-chip liquid cooling technology that serves hyperscale operators, along with year-to-date sales growth exceeding 100%.

Why it matters

As AI workloads push data centers toward unprecedented power densities, traditional air cooling becomes insufficient. Liquid cooling systems can handle higher heat loads while potentially reducing water consumption through closed-loop designs—a combination that addresses both performance and sustainability pressures facing the industry. Ecolab's move signals that infrastructure providers see thermal management as a strategic differentiator, not just an operational necessity.

Integrated platform targets 2026 launch

Ecolab plans to introduce a combined product at the Supercomputing conference in Chicago in November 2026. The platform will merge CoolIT's cooling distribution units and cold plates with Ecolab's digital optimization software and cooling fluids under the 3D TRASAR brand.

The system is designed to provide real-time visibility into cooling performance, power efficiency, and water usage. Ecolab emphasizes that closed-loop architectures can push facilities toward near-zero water footprints while supporting advanced chip designs including NVIDIA's Vera Rubin and Grace Blackwell platforms.

NVIDIA engineers Ali Heydari and Saket Karajgikar confirmed their collaboration with both companies across coolant qualification, health monitoring, and infrastructure development for next-generation AI systems.

Financial targets and growth trajectory

The acquisition reshapes Ecolab's Global High-Tech division, which generated approximately $150 million in annual sales in 2021. With the additions of Ovivo and now CoolIT, the division is approaching $1.5 billion in annualized sales for 2026. Ecolab has set a target of $4 billion in annual sales by 2030 with 25% operating margins.

The company expects 2026 adjusted diluted earnings per share between $8.03 and $8.23, representing 7% to 9% growth compared to 2025. Organic sales growth is projected to accelerate to 6% to 7% in the second half of 2026.

Addressing resource constraints

Ecolab Chairman, President and CEO Christophe Beck framed the acquisition as enabling AI infrastructure to scale while managing environmental impact. "Water is at the heart of it all," Beck stated. "It is needed to produce chips, power and cool them."

The combined entity targets the full AI value chain: ultra-pure water for semiconductor manufacturing, water systems for power generation, and direct liquid cooling for data centers.

Beck emphasized that the industry's focus on water and energy efficiency should drive better design rather than slower deployment. "The answer is not to slow innovation," he said. "It is to build it better."
