Ecolab has completed its acquisition of CoolIT Systems, adding direct liquid cooling hardware to Ecolab’s data center and high-tech portfolio. The deal brings CoolIT’s liquid-cooling products—built for high-density compute—under Ecolab’s Global High-Tech business as AI infrastructure pushes rack power and heat flux beyond what air cooling can handle economically.
Ecolab acquired CoolIT for approximately $4.75 billion. Ecolab also reported that CoolIT’s year-to-date sales have grown more than 100%, attributing that growth to increased liquid-cooling demand in AI data centers.
Ecolab said it plans to introduce an end-to-end “3D TRASAR” cooling platform at Supercomputing in November 2026 in Chicago. The planned platform combines CoolIT technologies, including cooling distribution units and cold plates, with integrated 3D TRASAR digital optimization and advanced cooling fluids. Ecolab said the system is intended to provide real-time visibility into cooling system performance, reduce cooling power demand, and improve power efficiency. The company also said it will use closed-loop solutions aimed at moving data centers toward a near-zero water footprint.
For data center engineers, the practical question is how tightly Ecolab can integrate chemistry, monitoring, and service with the physical liquid-cooling stack. CDUs, cold plates, and fluids live or die on details like contamination control, materials compatibility, and long-term stability under real operating conditions, not just peak thermal performance.
NVIDIA cited existing work with Ecolab and CoolIT across “coolant qualification, coolant health monitoring, cooling infrastructure development, and next-generation AI factory technologies.” “Through collaborations spanning NVIDIA engineering labs, research programs, and large-scale AI infrastructure deployments, Ecolab and CoolIT have consistently demonstrated strong technical expertise, innovation, and responsiveness,” said Ali Heydari, technical director and distinguished engineer at NVIDIA, and Saket Karajgikar, senior engineering manager and ASME fellow at NVIDIA.
Ecolab said its Global High-Tech business is approaching $1.5 billion in 2026 annualized sales after adding Ovivo and CoolIT, up from approximately $150 million in annual sales in 2021. The company is targeting $4 billion in annual sales for the Global High-Tech business by 2030, with operating income margins of 25%.
