Special Feature 6 | Thermal Management Industry Chain: Four Billion-Dollar Acquisitions in One Year—What Are the Giants Buying?

Data Sources: Dell’Oro, Grand View Research (GMI), company announcements (Eaton / Ecolab / Trane / Vertiv / Modine), and publicly available industry reports. The conclusion of our previous article on the power supply chain left a hook: 800V power delivery and liquid-cooling piping are now being delivered within the same server rack—electricity and heat are converging. This article focuses on the thermal side—the thermal management industry chain. First, consider this timeline—its pace is among the densest across the entire AI hardware sector. Eaton acquired Boyd, a thermal management leader, for $9.5 billion, instantly securing approximately $1.5 billion in liquid-cooling revenue; water treatment giant Ecolab acquired CoolIT—the leading liquid-cooling provider—for $4.75 billion in March 2026; HVAC giant Trane acquired LiquidStack, a company specializing in immersion cooling; and Vertiv acquired Strategic Thermal Labs. Power infrastructure giants, water chemistry leaders, and HVAC titans have, within roughly one year, lined up to write multi-billion-dollar checks for liquid-cooling technologies. When industry giants enter via acquisition rather than internal R&D, it signals that the market window for this category has already narrowed beyond the typical R&D cycle. This article follows those checks to dissect the thermal management industry chain layer by layer: Where is the money flowing? Who’s securing strategic positions? Where is competition intensifying? And where do hidden, underappreciated business opportunities still lie? I. Core Thesis: Liquid Cooling Has Evolved from a Niche Product into Mainstream Infrastructure Our earlier article on power and thermal management explained the underlying physics: Air cooling hits its ceiling at 20–30 kW per rack, while AI racks now exceed 100 kW—e.g., the GB200 NVL72 consumes ~120 kW. Liquids must therefore make direct contact with chips. This article adds the industrial logic: How large is this shift from air to liquid cooling—and how is value distributed across the chain? Market size figures: The liquid-cooling market is projected to reach ~$4.8 billion in 2025, ~$6.0 billion in 2026, and ~$27.1 billion by 2035—a compound annual growth rate (CAGR) of ~18%. Its fundamental value proposition can be distilled into one sentence: Liquid cooling reduces cooling energy consumption by over 30% compared to conventional refrigeration. In an era where “saving electricity equals expanding compute capacity,” every watt saved on cooling directly translates into sellable computing power. That is the logic behind the giants’ checks. II. Industry Narrative: Ecolab’s $4.75 Billion Purchase Is Not About Hardware Among the four acquisitions, Ecolab’s acquisition of CoolIT deserves special attention—because it’s most easily misunderstood. Ecolab is a global water treatment leader, primarily providing industrial water chemistry solutions—corrosion inhibition, scale prevention, and water quality monitoring. Its $4.75 billion acquisition of CoolIT—a top-tier provider of CDUs (Coolant Distribution Units) and cold plates—prompted an initial market reaction of “a water treatment firm venturing into hardware.” But the real strategy lies in the business model: Hardware sells once; chemicals generate recurring annual revenue. Once a liquid-cooling system is operational, coolant degrades, piping corrodes, and water quality requires continuous monitoring—creating a recurring revenue stream built on consumables and services. This is precisely Ecolab’s core competency. By bundling CoolIT’s CDU hardware with its own coolant chemistry formulations and water management services, Ecolab isn’t acquiring just an equipment manufacturer—it’s securing the “consumables entry point” for the entire liquid-cooling era.

ESG Investing Demystified: Top Companies Worth Watching on Wall Street (with Stock Tickers)

According to WallStreetCN, as 'sustainable assets' have become the preferred choice for governments, pension funds, and corporations seeking to reduce their carbon footprints and better fulfill social responsibilities, the ESG concept has drawn enthusiastic support from official institutions and capital markets. By the end of 2020, sustainable investment assets in the U.S., Europe, Australia, Canada, and Japan had reached $35.3 trillion—up more than 50% since 2016. Cathie Wood’s ARK Investment Management recently announced plans to launch a new Transparency ETF. This fund deliberately excludes sectors such as banking, alcohol, and oil & gas. Analysts view this ETF as reflecting ARK’s vision for ESG investing. In a report released Thursday, RBC Capital Markets analysts Ashish Sabadra and John Mazzoni stated: “With the pandemic nearing its peak and the surge in ESG-driven investment, economic reopening will place greater emphasis on health, hygiene, and safety—thereby boosting demand for business services. Specifically, demand for cleaning/disinfection, outsourced facilities management, unified leasing, and food services should all drive steady growth among commercial service providers.” RBC also noted that digital transformation further enhances operational efficiency for commercial service companies—as well as employee and customer satisfaction. Additionally, RBC identified three commercial service firms expected to outperform the broader market: 1. Ecolab (ECL) Ecolab specializes in water conservation, sanitation, and infection prevention services. Analysts commented: “Ecolab holds leadership positions in personal hygiene/disinfection solutions and water treatment. Heightened attention stemming from the pandemic and ESG-driven water conservation initiatives will further elevate its profile.” “In this highly fragmented industry, Ecolab offers products and services across dozens of verticals—achieving exceptional scale. Moreover, the company boasts strong R&D capabilities, holding thousands of patents and leveraging predictive analytics technology,” said RBC analysts. RBC Capital Markets set a target price of $260 for the stock—implying approximately 15% upside from current levels. 2. Cintas (CTAS) Cintas primarily provides corporate uniforms and apparel, as well as first-aid, safety, cleaning, and restroom supplies and services.
