Data Center Chillers Market Size & Share 2026-2035

Data Center Chillers Market Size

The data center chillers market was valued at USD 2.6 billion in 2025 and is projected to reach USD 6.4 billion by 2035, expanding at a 9.6% CAGR from 2026 to 2035.

Growth is being shaped less by conventional facility expansion than by the thermal consequences of AI-oriented computing: global data center electricity demand is projected to rise from 415 TWh in 2024 to 945 TWh by 2030, while AI-accelerated servers are expected to increase power consumption by about 30% annually ^{[1]International Energy Agency, "Energy and AI: Energy Demand from AI," iea.org}. Chillers therefore increasingly sit within a wider plant architecture that must manage conventional air cooling, liquid loops for dense compute zones, and tighter operating-efficiency targets.

Cooling can account for 7% to 30% of a data center's electricity use, depending on facility design and workload mix. This makes chiller selection consequential for both operating expenditure and power availability. DOE guidance identifies cooling-system efficiency of 0.6–1.1 kW per ton in high-performing facilities and places recommended server-inlet conditions within an 18°C–27°C range ^{[2]U.S. Department of Energy, "Best Practices Guide for Energy-Efficient Data Center Design," energy.gov}. These requirements favor equipment capable of maintaining efficiency under changing load profiles rather than systems optimized only for full-load performance.

The market's regional pattern reflects different combinations of capacity growth, climate, water availability, and regulation. North America represented USD 1,394.4 million, or 49.9%, of the market in 2026. Asia Pacific accounted for USD 933.3 million, or 33.4%, and is forecast to grow fastest at 10.8% CAGR through 2035. Europe's growth is comparatively more compliance-led, particularly where new and existing facilities must meet progressively stricter energy-performance and heat-reuse obligations under Germany's Energy Efficiency Act.

Capacity growth alone does not determine demand. Electricity access, water availability, and operating-performance rules increasingly determine which cooling topology can be deployed in a given market. Suppliers that can combine large cooling blocks, economization, controls, and low-water configurations are positioned to benefit as operators move from single-system specifications to site-specific thermal strategies.

Key Drivers

Drivers Impact Analysis

Exponential growth in hyperscale and edge data centers

Hyperscale facilities are the largest end-use segment, representing USD 1,263.0 million and 45.2% of market value in 2026, with a projected 10.8% CAGR through 2035. Large campus development concentrates thermal demand into fewer but more complex projects, raising the importance of modular capacity, redundancy, and plant-level controls. The estimated contribution of hyperscale and edge expansion to market CAGR is +3.2%, with the strongest effect in North America and Asia Pacific over the short to long term.

The driver is reinforced by the scale of the broader power buildout. Global data center power capacity is projected to rise from 200 GW in 2024 to 382 GW by 2030 ^{[3]S&P Global, "Data Center Sustainability Faces Challenges Amid Growth," spglobal.com}. For chiller suppliers, this shifts commercial emphasis toward designs that can be replicated across campuses while accommodating local climate, grid, and water constraints.

Rising rack power densities from AI/HPC workloads

AI computing changes the cooling requirement because the additional electrical load becomes concentrated around high-density compute clusters rather than distributed evenly across a hall. AI-accelerated server electricity consumption is expected to grow by about 30% annually. That profile favors chilled-water and liquid-loop configurations capable of serving dense zones without requiring an entire facility to abandon air cooling.

The estimated impact of AI/HPC density on market CAGR is +2.8%, led by the U.S. and China over the short to medium term. The commercial opportunity is not confined to greenfield AI campuses: colocation operators and enterprise sites need selective upgrades that can support liquid-cooled clusters alongside legacy air-cooled halls.

Stringent energy efficiency and sustainability regulations

Efficiency regulation is moving cooling systems from a facilities consideration to a compliance variable. Germany's EnEfG requires new data centers commissioned after July 1, 2026 to meet a maximum PUE of 1.2. Existing sites face maximum PUE thresholds of 1.5 from 2027 and 1.3 from 2030, alongside escalating energy-reuse-factor requirements ^{[4]White & Case, "Data Center Requirements Under the New German Energy Efficiency Act," whitecase.com}. Such requirements elevate the value of part-load efficiency, free cooling, heat-recovery readiness, and controls integration.

This driver contributes an estimated +2.1% to CAGR, with Europe leading the effect over the medium to long term. Regulations do not prescribe a single chiller technology, but they narrow the acceptable performance envelope and make lifecycle energy performance more influential in procurement.

Upgrades and retrofits of existing data centers

Replacement deployments represented USD 718.1 million, or 25.7%, of market value in 2026 and are projected to grow at 8.2% CAGR through 2035. The retrofit cycle is being extended by AI readiness requirements and compliance pressures: operators must improve cooling performance without necessarily rebuilding entire facilities.

The estimated contribution of upgrades and retrofits is +1.5% to CAGR, particularly in North America and Europe over the short to medium term. Retrofit projects favor suppliers that can phase capacity additions, integrate with installed controls and piping, and demonstrate operational gains under occupied-facility conditions.

Key Restraints

Restraints Impact Analysis

High capital investment and infrastructure costs

Chiller projects often require expenditure beyond the equipment itself, including electrical distribution, pumps, heat-rejection systems, controls, piping, redundancy, and site preparation. This raises the capital threshold for water-cooled central plants and hybrid architectures, particularly when a facility is simultaneously addressing utility interconnection limits or resilience requirements.

The estimated drag from capital intensity is -1.8% on market CAGR, most visibly in capital-constrained markets over the short to medium term. The restraint strengthens demand for modular air-cooled systems in fast-track projects, but it also creates a commercial opening for suppliers that can quantify energy savings, support phased deployment, and reduce commissioning risk.

Water scarcity concerns limiting water-cooled systems

Water efficiency is becoming a siting and operating constraint rather than a secondary environmental metric. S&P Global estimates that 43% of data centers are located in areas of high water stress, while 60% of China's data centers face high water-stress conditions. Water-cooled systems retain an efficiency advantage in many large facilities, but their suitability increasingly depends on local water rights, drought exposure, and community scrutiny.

This restraint is estimated to reduce CAGR by -1.3% over the medium to long term, particularly in the western U.S., China, the Middle East, and other water-stressed areas. It does not eliminate water-cooled demand; instead, it creates a technology-selection trade-off between electricity efficiency and water resilience, accelerating interest in air-cooled, dry-cooled, adiabatic, and hybrid configurations.

A facility that cannot secure water, power, or construction capacity cannot monetize a superior kW-per-ton figure. The strongest product propositions will increasingly link equipment performance to a credible site-level solution: lower water dependence, staged capital deployment, and measurable performance under local ambient conditions.

Data Center Chillers Market Segment Analysis

By Product

Water-cooled chillers accounted for 62.0% of market value in 2026 and are forecast to expand at approximately 10.0% CAGR through 2035. Their position is strongest in hyperscale and large colocation facilities where multi-megawatt scale and lifecycle energy efficiency justify more complex heat-rejection infrastructure. Air-cooled chillers held 32.9% share and are expected to grow at approximately 9.2% CAGR, supported by shorter deployment cycles and lower water exposure. Glycol-cooled chillers represented 5.1% share and are projected to grow at about 6.7% CAGR, serving specialized applications where freeze protection or loop isolation is required.

The product mix is being determined by site conditions rather than a universal technology hierarchy. Water-cooled systems remain compelling where water access and plant scale support their operating economics, while air-cooled platforms gain when water restrictions or rapid capacity additions dominate procurement.

By Technology

Screw chillers led the market with 48.1% share in 2026 and are expected to grow at approximately 9.4% CAGR. Centrifugal chillers represented 24.7% share and are projected to expand at about 10.5% CAGR, reflecting their relevance in larger-capacity installations. Scroll chillers held 15.2% share and are forecast to grow at approximately 8.1% CAGR, while absorption chillers accounted for 4.1% and are projected to grow at about 7.0% CAGR.

Magnetic-bearing chillers held 7.9% share in 2026 but are expected to record the fastest technology growth at approximately 11.2% CAGR. DOE indicates that magnetic-bearing chiller compressors can provide about 49% average power savings compared with conventional alternatives in suitable applications ^{[5]U.S. Department of Energy, "Magnetic-Bearing Chiller Compressors," energy.gov}. Their growth reflects the increasing value of oil-free operation and efficiency under variable-load conditions, although the premium remains easier to justify in large, continuously operated facilities than in smaller installations.

By Cooling Capacity

The >2,000 kW category is forecast to grow fastest at approximately 12.7% CAGR through 2035. This reflects the concentration of AI-oriented capacity in hyperscale campuses and large colocation facilities, where higher-capacity systems reduce equipment count and simplify integration with central plants. The 1,000–2,000 kW segment is projected to grow at about 10.2% CAGR, serving a broad range of large enterprise and colocation deployments.

Smaller categories remain commercially relevant but follow different demand patterns. The 500–1,000 kW segment is forecast to grow at approximately 7.7% CAGR, while the <500 kW category is expected to expand at about 6.5% CAGR. These ranges remain important for distributed deployments, smaller facilities, and phased retrofit work, but they capture less of the concentrated AI-driven expansion.

By Data Center

Hyperscale data centers accounted for USD 1,263.0 million, or 45.2%, of the market in 2026 and are forecast to grow at approximately 10.8% CAGR. Colocation data centers represented USD 908.2 million, or 32.5%, and are expected to grow at about 9.8% CAGR. These two segments set the market's equipment-development agenda because their projects require high availability, repeatable designs, and flexible thermal support for mixed tenant workloads.

Enterprise data centers accounted for USD 491.8 million, or 17.6%, in 2026 and are projected to grow at approximately 6.6% CAGR. Edge data centers represented USD 131.3 million, or 4.7%, and are forecast to expand at about 5.0% CAGR. Enterprise and edge demand is more dependent on retrofit feasibility, local service coverage, and compact equipment configurations than on the multi-megawatt standardization seen in hyperscale facilities.

By Data Center Size

Large data centers held 60.2% share in 2026 and are projected to grow at approximately 9.9% CAGR. Their scale supports advanced central plants, redundancy strategies, and sophisticated controls, allowing suppliers to compete on lifecycle efficiency and integration. Medium data centers represented 25.0% share and are forecast to grow at approximately 10.3% CAGR, benefiting from expansion in regional colocation and enterprise modernization.

Small-scale data centers accounted for 14.8% share and are projected to grow at approximately 7.0% CAGR. Their purchasing decisions are more sensitive to installation simplicity, physical footprint, and service responsiveness, creating different competitive conditions from large-campus projects.

By Deployment

New installations represented USD 2,076.2 million, or 74.3%, of market value in 2026 and are forecast to grow at approximately 10.0% CAGR through 2035. Greenfield projects allow operators to specify integrated cooling architectures from the outset, including liquid-cooling support, free cooling, and controls coordination.

Replacements accounted for USD 718.1 million, or 25.7%, of the market in 2026 and are expected to grow at approximately 8.2% CAGR. This segment has a different value proposition: equipment must improve efficiency and capacity while fitting within existing space, piping, electrical, and uptime constraints. The replacement market therefore rewards modularity and predictable commissioning as much as peak performance.

The most important procurement divide is between standardized greenfield campuses and constrained operating sites. Greenfield demand favors integrated, high-capacity plants with room for liquid-cooling expansion. Retrofit demand favors equipment that can deliver measurable performance gains without disrupting operations. Manufacturers that address both pathways can reduce exposure to project-cycle volatility.

Data Center Chillers Market Regional Analysis

North America

North America was the largest market in 2026, valued at USD 1,394.4 million and representing 49.9% of global revenue. The region is projected to expand at approximately 9.4% CAGR through 2035. U.S. growth is supported by the anticipated increase of roughly 240 TWh in data center electricity use by 2030, while Canada's 10.0% CAGR exceeds the U.S. rate of approximately 9.3%.

The U.S. combines the largest AI and hyperscale demand base with meaningful water and power constraints in several development corridors. Canada's cooler climate can improve the value proposition for economization, but local project economics still depend on grid availability and facility location. Across both countries, chiller procurement increasingly balances rapid air-cooled capacity additions with water-cooled or hybrid central plants for long-term expansion.

Europe

Europe represented USD 357.7 million, or 12.8%, of the market in 2026 and is projected to grow at approximately 7.8% CAGR through 2035. Germany is forecast to expand at about 7.0%, while the rest of Europe is projected to grow at approximately 8.0%. Germany's EnEfG is a key market-shaping factor because it establishes defined PUE thresholds for new and existing sites, mandates increasing energy-reuse performance, and requires renewable-electricity sourcing targets.

The UK, France, Italy, Spain, Sweden, Switzerland, the Netherlands, and Poland reflect distinct combinations of climate, power availability, and planning requirements. This makes Europe a market for site-specific solutions rather than a single regional specification. Equipment that supports economization, efficiency verification, and heat-reuse readiness can gain relevance where compliance requirements influence plant design from the earliest project stage.

Asia Pacific

Asia Pacific accounted for USD 933.3 million, or 33.4%, of global market value in 2026 and is forecast to grow at the fastest regional rate of approximately 10.8% CAGR through 2035. Deloitte estimates that Asia Pacific could attract USD 800 billion in data center investment by 2030, with regional electricity demand increasing by 50% by 2035 ^{[6]Deloitte, "Powering Asia Pacific's Data Centre Boom," deloitte.com}. This investment creates a large addressable base, but the region's climate diversity and infrastructure constraints prevent a standardized cooling approach.

China is projected to grow at approximately 10.5% CAGR, while the rest of Asia Pacific is expected to grow at about 11.2%. China's water-stress exposure increases the importance of low-water thermal designs in affected areas. Japan, South Korea, India, Australia, New Zealand, Singapore, and Indonesia present different design conditions, ranging from climate-driven economization potential to high-density urban sites and fast-growing cloud capacity. This favors modular and hybrid systems that can be adapted to local operating environments.

Latin America

Latin America was valued at USD 47.5 million in 2026 and represented 1.7% of global revenue. The market is forecast to grow at approximately 5.4% CAGR through 2035. Brazil and Mexico provide the region's principal scale opportunities, while Argentina and Chile add demand shaped by localized digital infrastructure development.

Cooling suppliers face a different market structure in Latin America than in North America or Asia Pacific. Projects may be smaller and more sensitive to capital availability, local service capability, and construction lead times. This favors solutions that can be deployed incrementally and maintained through established regional support networks.

MEA

The Middle East and Africa market was valued at USD 61.5 million in 2026, accounting for 2.2% of global revenue, and is projected to grow at approximately 6.5% CAGR through 2035. South Africa, Saudi Arabia, and the UAE are the region's spotlighted markets. High ambient temperatures and water-management considerations make thermal design especially consequential in these locations.

The region's opportunity lies in cooling systems engineered for difficult operating environments rather than in simple capacity addition. Air-cooled, dry-cooled, and hybrid configurations can be attractive where water conservation, high outdoor temperatures, and resilience requirements outweigh the energy advantages of conventional water-cooled approaches.

The regional technology mix will increasingly be governed by the local balance between power, water, climate, and regulation. Water-cooled central plants retain a strong role in suitable large-scale locations, but air-cooled and hybrid designs gain strategic value where permitting, water stress, or deployment speed determine whether a project can proceed. Regional service infrastructure and controls expertise will therefore become more important competitive assets.

Data Center Chillers Market Share & Competitive Landscape

The market is concentrated among large HVAC and mission-critical infrastructure suppliers. Johnson Controls held a 20.9% share in 2025, followed by Trane Technologies at 18.7%, Carrier Global at 14.5%, Daikin Industries at 12.0%, and Vertiv at 8.1%. The top five companies collectively accounted for 74.2% of market value, while the top seven accounted for 82.6%. This concentration reflects the value placed on product breadth, project execution capacity, controls integration, and lifecycle service support in critical-facility procurement.

Johnson Controls is the market leader and has aligned its offering with high-density, water-constrained deployment requirements. Its February 2026 YORK YDAM launch introduced an air-cooled magnetic-bearing centrifugal chiller designed for high-density multistory data centers and AI factories, with up to 3.5 MW of capacity per unit and zero water use ^{[7]Johnson Controls, "Johnson Controls Launches YORK YDAM, the Ultimate High-Density Chiller for Multistory Data Centers and AI Factories," johnsoncontrols.com}. The launch illustrates how suppliers are targeting dense urban and water-sensitive sites where conventional water-cooled plant configurations may be less practical.

Trane Technologies, Carrier Global, and Daikin Industries compete from positions of scale across air-cooled and water-cooled equipment categories. Their commercial relevance rests on delivering reliable capacity across multiple project sizes while supporting efficiency-oriented specifications. Vertiv's 8.1% share reflects the strategic importance of mission-critical integration, where cooling decisions are increasingly tied to power, controls, and facility-level resilience.

Schneider Electric held 4.8% market share in 2025 and is extending its position through integrated infrastructure commitments. Its November 2025 USD 1.9 billion supply-capacity agreement with Switch included Uniflair chillers using oil-free, variable-speed centrifugal compressors and integrated free cooling ^{[8]PR Newswire, "Schneider Electric and Switch Expand Partnership With USD 1.9 Billion Supply Capacity Agreement to Power AI Factories," prnewswire.com}. The agreement demonstrates how capacity assurance and integrated infrastructure supply can matter as much as standalone chiller performance for AI-factory projects.

Mitsubishi Electric, with 3.6% market share, LG Electronics, STULZ, Rittal, and Airedale International form an important competitive group across precision cooling, controls, regional delivery, and specialized data center applications. Airedale International's TurboChill 3+MW platform, launched in early 2026 for GPU-dense data centers, illustrates the industry's response to higher unit-capacity requirements and the need for broader free-cooling operating ranges.

Thermax, Dimplex Thermal, Blue Star, Dunham-Bush, Aermec, and Motivair contribute through regional execution, specialized thermal solutions, and application-specific engineering. Their competitiveness depends on the ability to match local project conditions, including climate, service expectations, and retrofit constraints, rather than competing solely on global scale.

ENGIE, Geoclima, and GalxC represent emerging participants whose potential lies in specialized, locally adapted, or lower-water cooling propositions. As water exposure and energy-performance requirements become more central to project approval, smaller specialists can gain opportunities where they demonstrate a clear advantage in a defined application or geography.
