The data center liquid cooling market hit $5.52 billion in December 2025. It is projected to reach $15.75 billion by 2030. That kind of growth rate attracts everyone. The question is who can actually manufacture at the scale the buildout demands.
Schneider Electric moved first among the industrial conglomerates. Their acquisition of Motivair in February 2025 gave them a dedicated liquid cooling portfolio: coolant distribution units, ChilledDoor rear-door heat exchangers, dynamic cold plates, and chillers. Since the acquisition, Motivair has opened a fourth production facility and is tripling global manufacturing capacity across plants in Buffalo, Italy, and India. Schneider is packaging this alongside their existing power distribution and thermal management products, creating an integrated stack that a facilities operator can buy from a single vendor. That bundling advantage is significant. Data center procurement teams prefer fewer suppliers, not more.
Vertiv has been in the cooling business longer than most of its competitors have existed. Their rear-door heat exchangers and CDU product lines are specified by default at several major colocation providers. Vertiv's advantage is installed base and channel relationships. The disadvantage is that they are defending market share against companies spending billions on acquisitions specifically designed to take it.
Eaton's $9.5 billion acquisition of Boyd Thermal was the largest pure-play cooling deal in data center history. Boyd brings manufacturing depth in heat exchangers, cold plates, and thermal interface materials. Eaton brings power distribution, UPS, and switchgear. The combination mirrors Schneider's strategy: own enough of the cooling and power stack to sell integrated solutions rather than individual components. Whether the integration happens fast enough to capture the 2026 and 2027 buying cycles is another matter. M&A at this scale takes time to produce coordinated product lines.
Below the three frontrunners, the field is crowded. CoolIT has shipped over a million direct liquid cooling connections and holds factory-integration partnerships with Dell, HPE, and Lenovo. Daikin acquired Chilldyne for its negative-pressure liquid cooling technology. Trane Technologies bought LiquidStack to gain an immersion cooling footprint. Munters, nVent, and dozens of smaller manufacturers are all competing for the same purchase orders.
The constraint is not demand. Demand is running ahead of supply across CDUs, cold plates, and rear-door heat exchangers. Lead times have stretched. Operators planning 2027 facility deliveries are placing cooling equipment orders now. The vendors who can ship on schedule will capture market share. The ones who cannot will lose it to whichever competitor can deliver faster, regardless of whose product benchmarks better on a spec sheet.
