Data Center Liquid Cooling Market Size & Share 2026-2035

Data Center Liquid Cooling Market Size

The data center liquid cooling market was valued at USD 4.8 Billion in 2025 and is projected to increase from USD 6 billion in 2026 to USD 27.1 billion by 2035, expanding at a CAGR of 18.2%.

The underlying shift is not simply a replacement of air-conditioning equipment. AI infrastructure is concentrating heat generation in processors, racks, and interconnects, making the thermal loop an increasingly important constraint on deployable computing capacity.

U.S. data centers consumed 176 TWh in 2023, equivalent to 4.4% of national electricity use, and the Lawrence Berkeley National Laboratory projects consumption of 325–580 TWh by 2028 as AI-oriented servers proliferate.^{[1]Lawrence Berkeley National Laboratory - eta-publications.lbl.gov} Globally, data center electricity demand is expected to more than double by 2030 to about 945 TWh.^{[2]International Energy Agency - iea.org} These loads change the economics of cooling: operators must assess whether a facility can remove heat at the required density, not only whether it can procure additional IT hardware.

Liquid cooling is gaining relevance because it can remove heat nearer to the chip and reduce the volume of air movement required around high-density equipment. CoolIT Systems reported that its 4,000W single-phase cold plate captures more than 97% of heat at 1.5 LPM/kW, illustrating the thermal performance being engineered for next-generation accelerators. The technology does not eliminate the need for facility cooling or residual air management, but it can shift a larger share of heat rejection into a controlled liquid loop.

The near-term constraint is implementation readiness. Many operators will retain hybrid air-and-liquid architectures because existing halls contain mixed workloads and because facility water, piping, service access, and heat-rejection design cannot be changed at the same speed as accelerator procurement. This creates an opening for retrofit-capable, modular solutions while preserving a longer-term role for purpose-built liquid-cooled campuses.

Key Drivers

AI and high-performance computing workloads. AI infrastructure is increasing both the scale and concentration of data center electricity demand. LBNL identifies AI-driven multi-GPU servers as a principal contributor to the projected increase in U.S. data center load through 2028. At the rack level, Meta presented its Catalina platform for NVIDIA Blackwell systems with support for up to 140 kW and a fully liquid-cooled architecture.^{[3]Meta Engineering - engineering.fb.com} Such configurations bring cooling decisions into the earliest stages of rack, power-distribution, and facility design.

Energy efficiency and sustainability requirements. Cooling efficiency is becoming a commercial consideration where electrical capacity is constrained or expensive. The U.S. Department of Energy's data center design guide identifies liquid cooling among the approaches used to manage high-density loads and improve facility efficiency when matched to the operating environment.^{[4]U.S. Department of Energy - energy.gov} Google reported fleet-wide PUE of 1.09 in 2025, demonstrating the value operators place on reducing non-IT energy overhead. Liquid cooling does not guarantee a particular PUE outcome, but warmer-water operation and reduced fan energy can improve the range of feasible facility designs.

Hyperscale and colocation expansion. JLL expects 10 GW of data center capacity to break ground globally in 2025, while noting that demand continues to outpace power and construction supply. Hyperscale leasing reached 7.4 GW in the third quarter of 2025, according to CRE Daily. Large projects create repeatable demand for factory-integrated liquid cooling, prefabricated distribution equipment, and standardized commissioning practices; they also intensify lead-time pressure for suppliers with limited manufacturing capacity.

Distributed architecture and edge deployment. The same thermal constraints are beginning to appear outside hyperscale campuses where localized AI inference, telecom workloads, and specialized computing are deployed in limited footprints. Smaller sites cannot always absorb the civil works associated with centralized liquid infrastructure, favoring contained and modular systems. This broadens the addressable market, although adoption in distributed sites remains sensitive to field-service availability and the economics of low-volume deployments.

Key Restraints

Capital intensity and retrofit complexity. Liquid cooling can require secondary loops, coolant distribution units, manifolds, leak detection, controls, and changes to heat rejection. The difficulty is greatest in operating facilities, where construction must be sequenced around availability commitments and mixed air-cooled and liquid-cooled IT estates. A strong efficiency case may still fail to secure capital approval if the operator cannot identify a credible migration path, customer downtime window, or utilization level for the upgraded capacity.

Technical and operating risk. Design choices concerning coolant selection, connector standards, flow control, water chemistry, and maintenance procedures introduce risks unfamiliar to some air-cooled data center teams. IEEE's 2025 overview of liquid-cooling safety requirements for AI and machine-learning data centers highlights the importance of safety considerations across direct-liquid and immersion approaches. Procurement is consequently moving toward suppliers that can validate the full system boundary rather than merely provide thermal hardware.

The market will not transition uniformly to immersion or two-phase systems. Single-phase direct-to-chip architectures offer a lower-disruption path for many deployments, while two-phase and immersion designs are more likely to be evaluated when density, footprint, or heat-reuse requirements make their additional complexity commercially defensible. Vendors that support multiple architectures can participate in both the retrofit cycle and the higher-density greenfield cycle.

Data Center Liquid Cooling Market Segment Analysis

Component

The solution segment is projected to grow from USD 3,429.2 million in 2025 to USD 14,828.1 million by 2035, at a 15.2% CAGR. It encompasses direct-to-chip equipment, immersion systems, rear-door heat exchangers, CDUs, heat exchangers, and related distribution hardware. Direct-to-chip offerings include cold plates and micro-channel coolers; immersion offerings include IT chassis and tub or open-bath systems; rear-door heat exchangers are available in active pumped and passive configurations.

Services are projected to expand from USD 1,394.6 million to USD 12,239.2 million, representing a 23.5% CAGR. Managed services include remote monitoring, performance optimization, and maintenance and support, while professional services cover consultation, design, installation, and deployment. Their higher growth rate reflects the fact that cooling performance depends on loop design and operation as much as on equipment specification.

Cooling mechanism

Single-phase liquid cooling is forecast to increase from USD 3,063.6 million in 2025 to USD 15,728.8 million by 2035, at a 17.2% CAGR. Its installed-base compatibility and more familiar fluid-management model support broad adoption. CoolIT's 4,000W cold plate announcement indicates that single-phase direct-liquid cooling continues to extend its performance range rather than ceding all high-density applications to more complex approaches.^{[5]CoolIT Systems - coolitsystems.com}

Two-phase cooling is projected to grow from USD 1,760.2 million to USD 11,338.5 million, at a 19.9% CAGR. The stronger rate reflects its role in high-heat-flux applications, although fluid requirements, controls, qualification procedures, and operating expertise can limit adoption. Carrier's February 2025 investment in ZutaCore, a developer of waterless two-phase direct-to-chip cooling, provides evidence of strategic interest in this technical pathway.^{[6]Carrier Global Corporation - ir.carrier.com}

Coolant

Water-based coolants remain the largest category, increasing from USD 2,165.9 million in 2025 to USD 10,881.1 million by 2035 at a 16.9% CAGR. Their accessibility and thermal characteristics make them suitable for many direct-to-chip systems, but they require disciplined materials compatibility and leak-management practices. Dielectric fluids are projected to increase from USD 1,299.0 million to USD 6,937.3 million at a 17.7% CAGR and are important where electrical non-conductivity supports immersion or specialized designs.

Synthetic fluids are forecast to grow at the highest coolant CAGR, from USD 737.6 million to USD 5,383.7 million at 21.3%. Mineral oils are projected to rise from USD 449.6 million to USD 3,118.2 million at 20.7%, and bio-based/natural coolants from USD 171.7 million to USD 747.1 million at 15.2%. The divergence implies that coolant selection will remain application-specific, shaped by thermal performance, equipment compatibility, maintenance requirements, and environmental objectives rather than a single industry-wide preference.

Data center size

Large data centers represent the largest size segment, rising from USD 2,334.2 million in 2025 to USD 12,637.7 million by 2035 at a 17.8% CAGR. They can spread CDUs, piping, and heat-rejection investments across substantial IT loads. Medium facilities are forecast to grow faster, from USD 1,849.4 million to USD 11,785.1 million at a 19.7% CAGR, as colocation operators and regional cloud providers use modular deployment to add high-density capacity without replicating hyperscale construction models. Small facilities are projected to grow from USD 640.1 million to USD 2,644.5 million at a 14.6% CAGR; their adoption case depends more heavily on packaged equipment and specialized local workloads.

Application

Server cooling is expected to advance from USD 3,521.4 million in 2025 to USD 18,676.4 million by 2035, at a 17.6% CAGR, reflecting the concentration of AI and HPC heat in CPUs and accelerators. Storage cooling is projected to grow faster, from USD 665.7 million to USD 5,115.7 million at 22.0% CAGR, while networking cooling rises from USD 436.6 million to USD 2,693.2 million at 19.4% CAGR. The faster growth in those categories indicates that dense AI clusters are extending thermal design beyond compute nodes to the data-movement and storage layers needed to sustain them. Other applications are projected to increase from USD 200.2 million to USD 581.9 million at 10.5% CAGR.

End use

Enterprise deployments are projected to grow from USD 2,150.9 million in 2025 to USD 10,093.4 million by 2035, at a 16.1% CAGR. Their lower growth relative to other end uses reflects the complexity of retrofitting mixed and often long-lived IT estates. Telecom service providers are forecast to rise from USD 1,013.0 million to USD 6,956.3 million at a 20.6% CAGR, supported by distributed computing and network-intensive workloads. Cloud service providers are projected to expand from USD 1,659.9 million to USD 10,017.6 million at a 19.1% CAGR, reflecting their role in deploying large AI clusters and establishing reference architectures.

Single-phase and water-based systems will remain commercially important because they provide a practical bridge between conventional data center operations and high-density computing. The faster growth of synthetic fluids and two-phase mechanisms should be interpreted as selective escalation at the performance frontier, not a wholesale replacement of direct-to-chip water-based cooling. Suppliers that clearly define the operating envelope of each architecture can reduce buyer uncertainty and protect margins against component commoditization.

Brazil remains central to regional demand, while Chile's 19.6% CAGR highlights the role of national power conditions and cloud-investment patterns. Colombia and Argentina add demand from growing digital infrastructure, but vendors must accommodate uneven procurement capacity and site-level infrastructure readiness across the region.

Middle East & Africa

The Middle East & Africa market is forecast to rise from USD 240.0 million in 2025 to USD 1,100.7 million by 2035, at a 15.5% CAGR. Saudi Arabia's 17.9% CAGR exceeds that of the UAE at 13.6%, while South Africa is projected to grow at 16.3%. High ambient temperatures, water constraints, and new sovereign-cloud and AI investments can strengthen the operating case for closed-loop liquid systems, but the smaller market base and heterogeneous infrastructure conditions moderate aggregate growth.

This fragmentation has commercial consequences. Global suppliers need common platforms for manufacturing scale, but regional success will depend on local fluid specifications, service capability, heat-rejection options, and compliance support. A solution designed only for greenfield hyperscale campuses may miss the medium-sized, regulated, or water-constrained installations that are likely to account for a growing share of incremental demand.

Data Center Liquid Cooling Market Share & Competitive Landscape

The five largest suppliers collectively account for 35% of the market in 2025, with Vertiv holding an 11.30% share. This level of concentration leaves room for specialist suppliers while favoring companies that can provide validated equipment, global service coverage, and integration with power and data center infrastructure.

Vertiv competes through liquid-cooling systems and hybrid cooling architectures that address high-density AI deployments. Its collaboration with Compass Datacenters on CoolPhase Flex combines liquid and air cooling in a multi-year supply arrangement, demonstrating the market's preference for transition architectures rather than abrupt all-liquid conversions.^{[8]Vertiv - vertiv.com} Schneider Electric has strengthened its cooling position through Motivair, its subsidiary following the October 2024 acquisition of a controlling interest. Schneider Electric and NVIDIA also announced a reference design for liquid-cooled AI clusters of up to 132 kW per rack for GB200 NVL72 systems.

Alfa Laval, Asetek, Boyd, CoolIT Systems, Green Revolution Cooling, LiquidStack, Rittal, Schneider Electric, Stulz, and Vertiv form the global-leader group. Alfa Laval's heat-transfer capabilities are relevant to facility-side heat rejection and heat reuse. Asetek and CoolIT Systems address direct-to-chip designs, while Green Revolution Cooling and LiquidStack serve immersion-oriented requirements. Boyd contributes thermal components, and Rittal and Stulz bring established data center cooling and regional support capabilities. CoolIT's manufacturing expansion in Calgary and its high-density CDU product launch illustrate how pure-play suppliers are scaling alongside technology development.

Regional players comprise Asperitas, DCX Liquid Cooling Systems, Delta Electronics, DUG Technology, Iceotope Technologies, Kaori Heat Treatment, and Submer Technologies. Their positions are often defined by specialization in immersion, localized engineering, manufacturing, or deployment support. Asperitas' February 2025 engineering alliance with Cisco, which connected its immersion platforms to Cisco UCS configurations, illustrates the value of pre-validated interoperability for broadening adoption.

Emerging players include Accelsius, Chilldyne, JETCOOL Technologies, LiquidCool Solutions, Midas Green Technologies, Seguente, and ZutaCore. These companies compete through differentiated thermal approaches, component innovation, and responsiveness to high-density requirements. Carrier's investment and technology partnership with ZutaCore provides external validation for two-phase direct-to-chip cooling, while also demonstrating that larger HVAC and infrastructure groups are seeking access to specialized liquid-cooling capability.

The competitive boundary is increasingly defined by who controls integration risk. Vendors able to coordinate IT interfaces, cooling distribution, controls, facility heat rejection, and commissioning can offer a more defensible proposition than suppliers competing solely on a single hardware specification. Consolidation is likely to remain selective, centered on technologies and service capabilities that shorten qualification cycles for AI infrastructure.
