The market is projected to reach USD 6.90 billion by 2035, a CAGR of 7.88% from 2025. **How fast is the Data Center Chiller Market growing?** 7.88% a year from 2025 to 2035, after 15.69% a year between 2020 and 2025, because new data center capacity keeps rising while warm-water AI cooling lowers the share of halls that need chillers. **What is a data center chiller?** USD 3.23 billion of 2025 spending covers the air-cooled and water-cooled chillers that remove heat from a data hall's chilled-water loop, plus their installation, replacement and service. Cooling towers, CRAH units, CDUs and pumps are excluded. **Which chiller type leads the Data Center Chiller Market?** 54.0% of 2025 value, or USD 1.75 billion, goes to air-cooled chillers, which grow 9.21% a year because they need no cooling-tower water. Centrifugal compressors lead by compressor type with 45.0%. **How much does a data center chiller cost per MW?** About USD 210,000 of chiller equipment per MW of IT load in a conventional hall and USD 260,000 in an AI hall in 2025, according to DC Market Insights estimates, or about USD 616 to USD 703 per ton before 18% installation. **Do AI data centers still need chillers?** 80% of new AI capacity used chillers in 2025, but DC Market Insights expects 50% by 2035 because NVIDIA's 45 °C liquid inlet design allows chiller-free dry coolers. Hot sites such as Riyadh and Mumbai keep chillers. **Which region leads the Data Center Chiller Market?** 42.0% of 2025 value, or USD 1.36 billion, is spent in North America. The Middle East and Africa grows fastest at 12.35% a year, and India is the fastest large country at 13.54%. **Who are the leading companies in the Data Center Chiller Market?** About 55% of 2025 value is held by Trane Technologies, Johnson Controls, Carrier Global, Daikin Industries and Vertiv together (DC Market Insights estimate). Mitsubishi Electric, LG Electronics, Modine, STULZ and Midea also compete. **How do refrigerant rules affect data center chillers?** Replacement chillers rise from USD 613.87 million in 2025 to USD 1.55 billion in 2035 as the US EPA 700 GWP limit (2025) and the EU F-gas ban on chillers with a GWP of 750 or more (2027) push older units out. **Why do Data Center Chiller Market estimates differ?** USD 3.76 billion in 2026 is the DC Market Insights figure for chillers and their installation and service at data centers only. Estimates that add cooling towers, pumps, air handlers, liquid cooling or comfort chillers come out several times larger. ## Dataset | Series | Value | Unit | | --- | --- | --- | | Market size 2025 | 3,230 | USD million | | Revenue CAGR | 7.88 | % | | Market size 2035 | 6,900 | USD million | ## Frequently asked questions ### What is the size of the Data Center Chiller Market in 2026?
