Ecolab has announced plans to acquire CoolIT Systems from investment firm KKR in a $4.75 billion all-cash deal, signaling a major push into the fast-growing market for liquid cooling solutions in AI-driven data centers.
Strategic Move to Capture AI Infrastructure Growth
The acquisition comes at a time when global demand for artificial intelligence infrastructure is surging. Tech companies are rapidly scaling up data center capacity, increasing the need for advanced cooling technologies that can handle higher chip densities and power loads.

The recent Gartner report said AI spending is expected to reach $2.52 trillion in 2026, growing 44 percent. A major share of this investment is directed toward AI infrastructure, including servers, GPUs, networking, and data centers, which form the backbone of AI deployments.
Gartner highlights that AI infrastructure and data centers are key drivers of overall IT spending, which is projected to hit $6.15 trillion in 2026.
IDC report forecasts continued acceleration in AI infrastructure investments, with spending expected to reach $758 billion by 2029.
Traditional air cooling systems are becoming less effective for modern AI workloads. As a result, liquid cooling solutions – like those developed by CoolIT – are gaining traction for their efficiency and ability to manage heat in high-performance computing environments.
CoolIT Systems provides liquid cooling technologies widely used by hyperscale and colocation data center operators. Its client base includes leading semiconductor companies such as Nvidia and Advanced Micro Devices, highlighting its strong position in the AI hardware ecosystem.
Strengthening Ecolab’s Digital and Water Solutions Portfolio
Ecolab, known for its expertise in water management, hygiene, and industrial solutions with annual revenues of $16 billion in 2025, aims to integrate CoolIT’s thermal engineering capabilities with its own strengths in water, chemistry, and digital monitoring systems. This combination is expected to transform Ecolab into a more comprehensive provider of cooling and fluid management solutions for next-generation data centers.
The company estimates that CoolIT will generate approximately $550 million in revenue over the next 12 months, offering a solid growth base as AI adoption accelerates globally.
Financial Impact and Deal Timeline
The acquisition is expected to close in the third quarter of 2026, subject to regulatory approvals and customary closing conditions. Ecolab anticipates that the deal will become accretive to its adjusted diluted earnings per share by 2028, reflecting long-term value creation from the transaction.
Despite the strategic rationale, Ecolab’s shares dipped slightly in premarket trading following the announcement, indicating cautious short-term investor sentiment.
Growing Importance of Liquid Cooling in Data Centers
The shift toward liquid cooling is becoming a defining trend in the data center industry. AI workloads require significantly more processing power, which in turn generates higher heat output. Liquid cooling systems offer improved thermal efficiency, reduced energy consumption, and better scalability compared to conventional air-based methods.
As companies invest heavily in AI infrastructure, the demand for advanced cooling solutions is expected to rise sharply, creating new growth opportunities for firms operating in this space.
Outlook: Positioning for the Future of AI and Data Centers
With this acquisition, Ecolab is positioning itself at the intersection of sustainability, water management, and AI infrastructure. By combining its legacy expertise with CoolIT’s cutting-edge cooling technologies, the company aims to play a critical role in enabling efficient and sustainable data center operations worldwide.
