Data Center Chillers Market to Surpass $6.4 Billion by 2035

TL;DR

• The global data center chillers market is projected to grow from USD 2.8 billion in 2026 to USD 6.4 billion by 2035 at a 9.6% CAGR, propelled by escalating rack densities from generative AI and high-performance computing workloads.
• Water-cooled systems remain the dominant technology, holding a 61.8% market share (USD 1.6 billion) in 2025 with a projected 10% CAGR. Meanwhile, air-cooled systems (32.9% share) are scaling rapidly in water-scarce regions.
• Technological innovation is shifting toward oil-free and magnetic-bearing platforms, which can cut compressor power consumption by up to 49% at part-load cycles to help operators hit strict Power Usage Effectiveness (PUE) targets.

The global data center chillers market is poised for significant expansion, projected to grow from USD 2.8 billion in 2026 to USD 6.4 billion by 2035. According to a comprehensive industry report published by Global Market Insights Inc., the market will advance at a steady compound annual growth rate (CAGR) of 9.6% during the forecast period. This follows a strong baseline year in 2025, where the market was valued at USD 2.6 billion.

The primary catalyst for this aggressive growth is the global transition into a hyper-digital era. The exponential rise of generative artificial intelligence (AI), machine learning, and high-performance computing (HPC) workloads has radically increased rack power densities. Because cooling demands scale directly with IT loads, modern multi-megawatt hyperscale and colocation facilities require massive, industrial-grade chiller systems to maintain operational stability and prevent thermal stress.

Water-Cooled Systems Dominate, Air-Cooled Solutions Scale in Arid Regions

• Water-Cooled Chillers: This segment dominated the landscape in 2025, capturing a 61.8% market share and generating USD 1.6 billion in revenue. Prized for their superior heat transfer efficiency and scalability, water-cooled systems are projected to grow at a 10% CAGR through 2035, especially across large-scale hyperscale campuses.
• Air-Cooled Chillers: Holding a 32.9% market share in 2025, air-cooled units are expanding rapidly due to speed-to-capacity advantages, simpler installation, and strict water-conservation mandates in drought-prone regions like the Western U.S. and Northern China.

The Rise of Oil-Free and Magnetic-Bearing Innovations

In response to tightening environmental policies and stringent Power Usage Effectiveness (PUE) targets, the industry is shifting rapidly toward technological innovations. Magnetic-bearing centrifugal chillers and oil-free platforms are emerging as key growth drivers. Validated data indicates these advanced systems can cut compressor power draw by up to 49% at part-load cycles, making them highly attractive to procurement teams retrofitting older halls or building out dedicated AI zones.

Regional Outlook: North America Leads, Asia-Pacific Accelerates

North America remains the largest market, valued at USD 1.3 billion in 2025, heavily propelled by massive domestic investments in AI infrastructure. Meanwhile, the Asia-Pacific region is slated to log the fastest growth rate with a 10.8% CAGR through 2035. Rapid infrastructure updates in China and aggressive government-backed digital initiatives in India are positioning APAC as a primary hub for future data center deployments.

Consolidated Competitive Landscape

The data center chillers market is highly consolidated, with the top five players, Johnson Controls, Carrier Global, Daikin, Trane Technologies, and Vertiv, collectively commanding 74.2% of the market in 2025. Johnson Controls emerged as the individual market leader, holding a 20.9% market share. Prominent players are actively introducing modular, water-free, and high-capacity units (such as recent 2026 launches from Panasonic and Johnson Controls) to capture emerging demand from generative AI infrastructures.
