Data Center Liquid Cooling Market to Surge

- The global market was valued at approximately $4.8 billion in 2025 and is projected to reach $27.1 billion by 2035. Other forecasts estimate the market could grow from $5.65 billion in 2024 to over $48 billion by 2034. - Liquid cooling can significantly improve a data center's Power Usage Effectiveness (PUE), a measure of energy efficiency. While traditional air-cooled facilities often have a PUE of 1.4 to 1.8, liquid cooling systems can achieve a PUE as low as 1.05-1.15. - Two dominant technologies are direct-to-chip cooling, which targets specific components like CPUs and GPUs with cold plates, and immersion cooling, where entire servers are submerged in a non-conductive fluid. Direct-to-chip solutions can be easier to retrofit, while immersion supports extremely high densities. - While upfront capital costs for liquid cooling can be higher, operational costs are typically lower due to reduced energy consumption. For a 10MW data center, switching to liquid cooling can result in $3-7 million in annual electricity savings. - The push is driven by rising server rack power density, which is expected to reach 15-20 kW per rack by 2025, with some AI clusters already exceeding 80 kW—a level traditional air cooling struggles to manage effectively. - Key market players include Vertiv, Schneider Electric, and CoolIT Systems, who are actively partnering with chip manufacturers. For example, Vertiv was selected as a primary partner for NVIDIA's advanced GB200 NVL72 systems. - Regulatory measures and sustainability goals are accelerating adoption. Germany's Energy Efficiency Act, for example, mandates that data centers achieve a PUE of 1.3 or lower by 2027, compelling operators to upgrade cooling technologies. - Liquid cooling facilitates waste heat reuse, where the captured thermal energy can be repurposed for district heating or other industrial applications, turning data centers from energy consumers into contributors to circular energy systems.
