Data Center Cooling Market Size & Share 2026-2035

Data Center Cooling Market Size

The global data center cooling market was valued at USD 20.5 billion in 2025, is expected to reach USD 24.2 billion in 2026, and is projected to expand at a 12.3% CAGR from 2026 to 2035, reaching USD 68.7 billion by 2035. The market encompasses purpose-built thermal management equipment and integrated hardware systems that regulate temperature, humidity, airflow, and heat rejection in data center facilities.

The Global Data Center Cooling Market is being reshaped by the move from conventional enterprise computing toward high-density AI training and inference deployments. This transition changes cooling from a supporting facility utility into a core design constraint, favoring engineered liquid systems, higher-capacity heat-rejection equipment, integrated controls, and service models capable of maintaining thermal reliability across increasingly complex facility architectures.

Data Center Cooling Market Trends, Growth Drivers & GMI Forecast Outlook

AI rack density is accelerating the transition toward liquid and hybrid cooling, but water availability, grid constraints, permitting requirements, and retrofit complexity will determine where and when projects translate into equipment orders. The forecast therefore reflects strong structural demand alongside uneven project conversion across geographies and facility types.

Key Drivers

Evidence anchors use cited external data; demand implications and forecast conditions represent GMI analysis.

Thermal design limits are becoming a direct procurement trigger for AI-capable facilities. As accelerator density rises, operators must manage heat closer to the chip and transport it through more controlled fluid systems, which increases the strategic role of CDUs, rear-door heat exchangers, immersion systems, facility chillers, and heat-rejection equipment. Dell'Oro identifies liquid cooling as moving from a specialized deployment toward a foundational requirement for AI-focused data center capacity ^{[1]Dell'Oro Group.[delloro.com](https://www.delloro.com/news/data-center-liquid-cooling-market-to-approach-7-billion-by-2029-as-ai-deployments-accelerate)}.

The installed base also changes the quality of market demand. Every additional commissioned cooling system creates requirements for control integration, condition monitoring, preventive maintenance, fluid management, and emergency-response capability. This attachment opportunity is especially consequential where liquid systems raise the operational consequences of inadequate thermal oversight.

Interface standardization is reducing one of the principal barriers to liquid-cooling adoption: project-specific integration risk. More consistent mechanical and coolant-loop requirements enable operators, server providers, and cooling suppliers to shorten qualification cycles. The resulting shift should widen liquid-cooling adoption beyond the earliest hyperscale deployments, although mainstream colocation and enterprise uptake will remain conditioned by facility readiness and service availability.

Key Restraints

Evidence anchors use cited external data; demand implications and forecast conditions represent GMI analysis.

Regulatory complexity can delay the point at which committed data center investment becomes an executable construction program. State requirements concerning water use, energy disclosure, siting, and infrastructure costs vary materially, increasing diligence requirements for operators with multi-market expansion plans. WilmerHale reported that more than 40 data center-focused state bills introduced during 2025 became law, underscoring the breadth of the emerging compliance burden ^{[2]WilmerHale. [wilmerhale.com](https://www.wilmerhale.com/en/insights/client-alerts/20260223-state-regulation-of-data-centers-emerging-trends-and-potential-legal-complexities)}.

The California framework illustrates how utility and water obligations can alter project economics. Requirements for operators to address infrastructure impacts can raise upfront capital needs and redirect development toward locations with more predictable approvals, lower water exposure, or more favorable power arrangements. The state's action also increases the importance of cooling designs that reduce water dependency and support transparent operating performance ^{[3]Office of Governor Gavin Newsom. [gov.ca.gov](https://www.gov.ca.gov/2026/09/21/governor-newsom-signs-most-comprehensive-data-center-laws-in-the-nation-providing-communities-more-control-on-water-electricity-and-land-use)}.

Retrofit constraints remain a distinct limitation from technology demand. Older air-cooled facilities may lack the structural capacity, piping routes, leak-detection systems, isolation capability, and maintenance access required for liquid cooling. Consequently, the most rapid adoption is likely to remain concentrated in greenfield hyperscale and purpose-built colocation projects, while legacy facilities extend the life of existing precision-air equipment.

Data Center Cooling Market Segment Analysis

By Product Type

The Global Data Center Cooling Market is shifting from equipment categories designed primarily for room-level air management toward systems that manage heat through the full facility chain, from the rack and coolant loop to central plant and heat rejection.

Precision Air Cooling (CRAC/CRAH/In-Row)

Precision air cooling generated USD 7.80 billion in 2025 and is projected to account for 25.0% of market revenue by 2035. The category remains essential in moderate-density environments, legacy enterprise estates, and mixed-technology halls. Its strategic role is changing, however, as advanced facilities reserve air systems for lower-density zones while deploying liquid solutions for AI infrastructure. Suppliers with large precision-air installed bases retain a service advantage, but future differentiation will depend on hybrid configurations and retrofit pathways.

Chillers (Air-Cooled & Water-Cooled)

Chillers are projected to reach USD 12.36 billion by 2035, expanding at an 11.1% CAGR (2026-2035).

Chiller demand benefits from the upstream facility requirements created by liquid cooling. Direct-to-chip and immersion architectures still require dependable heat transfer and rejection beyond the rack, positioning chillers as a durable part of both conventional and advanced thermal designs. Equipment selection will increasingly favor efficiency, higher-temperature operation, modularity, and compatibility with heat-reuse strategies.

Liquid Cooling (CDU/Immersion/DLC)

Liquid cooling represented 17.1% of market revenue in 2025 and is projected to reach USD 22.67 billion by 2035.

Liquid cooling is the central technology transition within the market because it addresses heat loads that room-level air systems cannot manage economically or reliably. The segment's value proposition extends beyond thermal capacity: it can enable denser compute deployment, more controlled operating conditions, and more flexible facility designs. Vendor competition is therefore moving toward engineering depth, deployment capability, coolant management, and lifecycle support.

Cooling Towers & Dry Coolers

Cooling towers and dry coolers generated USD 2.30 billion in 2025 and are expected to grow at an 11.0% CAGR (2026-2035).

These systems are critical to facility-level heat rejection and are increasingly shaped by local water availability, ambient climate, and operating-cost constraints. In water-stressed locations, dry and adiabatic alternatives can gain preference despite their different capital and energy profiles. The category's growth is tied not only to new data center capacity but also to the need to redesign heat-rejection systems around denser computing environments.

Controls & BMS Systems

Controls and BMS systems are projected to account for 7.0% of market revenue by 2035 and to expand at a 12.4% CAGR (2026-2035).

Controls become more valuable as operators run legacy air-cooled zones alongside liquid-cooled AI deployments. Integrated hardware can improve visibility across temperature, airflow, coolant distribution, and equipment performance while reducing the risk of localized thermal events. The segment is positioned to benefit from demand for coordinated operation across increasingly heterogeneous cooling estates.

Services & Aftermarket

Services and aftermarket activity is projected to reach USD 4.80 billion by 2035 and accounted for 6.8% of market revenue in 2025.

The service opportunity expands with the installed base and with the complexity of deployed systems. Liquid cooling introduces operational requirements around fluid quality, leak management, component reliability, and technician capability, supporting deeper vendor relationships after installation. For equipment providers, this creates a more recurring revenue stream that can moderate exposure to project-based capital-equipment cycles.

By End Use

Hyperscale/Cloud Data Centers

The declining share reflects continued migration of workloads toward cloud and colocation environments, along with consolidation of remaining on-premises estates. Cooling demand will persist through replacement, reliability upgrades, and selective modernization, but large-scale greenfield investment is less central than in hyperscale and colocation markets. Retrofit feasibility will continue to determine the pace of liquid-cooling adoption.

Edge Computing Data Centers

Edge computing data centers are expected to grow at a 15.0% CAGR (2026-2035) and reach USD 5.49 billion by 2035.

Edge deployments create a different cooling requirement from centralized AI campuses: smaller footprints, distributed locations, varied climate conditions, and limited on-site technical support. This supports demand for compact, resilient, modular systems that can be rapidly installed and remotely monitored. Cooling suppliers that combine standardized products with strong local service capacity are well positioned in this segment.
