According to MarketsandMarkets’ report titled “Data Center Liquid Cooling Market by Component (Solution and Services), End User (Colocation Providers, Enterprises, and Hyperscale Data Centers), Cooling Medium, Data Center Type, Type of Cooling, Enterprise, and Region – Global Forecast to 2033,” the global market for data center liquid cooling is valued at approximately USD 4.07 billion in 2026 and is expected to grow significantly to USD 27.65 billion by 2033, registering a compound annual growth rate (CAGR) of 31.5% during this period.

Market Size & Forecast

Key Trends and Insights
The market is set for strong expansion, largely driven by the rising demand for artificial intelligence (AI) workloads and high-performance computing (HPC). Increasing rack densities—often reaching 30–50 kW—are making traditional air-based cooling systems less effective. Consequently, advanced solutions such as direct-to-chip cooling, immersion cooling, and cold plate technologies are becoming increasingly critical.

Small and mid-sized data centers are expected to experience the fastest growth, with a projected CAGR of 33.9%, as they increasingly adopt liquid cooling to handle high-density computing requirements. Among cooling technologies, immersion cooling is anticipated to lead growth with a CAGR of 34.1%.

In terms of components, solutions dominate the market, accounting for an estimated 63.5% share. By end user, hyperscale data centers hold the largest share at 76.4%, reflecting their massive infrastructure and performance demands.

Within enterprise segments, industries such as BFSI, IT & telecom, healthcare, and retail are key adopters, with IT & telecom projected to grow the fastest at a CAGR of 29.6%, fueled by 5G expansion, cloud services, and AI-driven applications.

Regarding cooling mediums, dielectric fluids—especially in immersion cooling systems—are gaining popularity due to their superior heat dissipation capabilities. Regionally, Asia Pacific is forecast to grow at the highest rate (32.8% CAGR), while North America is expected to maintain the largest market share.

Growth Drivers
The surge in hyperscale and edge data centers, driven by technologies like 5G, IoT, and cloud computing, is accelerating the need for efficient cooling solutions. Regulatory initiatives such as the EU Energy Efficiency Directive and the rising global energy consumption of data centers—expected to reach 8% of total energy use by 2030—are also pushing adoption. Advances in dielectric fluids and two-phase cooling technologies are further shaping the future of the market.

Segment Highlights

Regional Outlook
North America is expected to lead the market, supported by the expansion of hyperscale facilities, strong adoption of AI workloads, and stringent environmental regulations. Increasing power demand—projected to reach 35 GW in the U.S. by 2032—along with a surge in data center construction, is making energy-efficient cooling solutions essential.

Competitive Landscape
Major companies operating in this market include Vertiv Group Corp., Schneider Electric, Super Micro Computer, Inc., Rittal GmbH & Co. KG, Green Revolution Cooling, Submer, LiquidStack, Iceotope, CoolIT Systems, and several others. Emerging players such as Giga-Byte Technology, TAS, and Teimmers are also gaining traction by focusing on niche segments and innovative solutions.

VIAVI Solutions Inc. has introduced the industry’s first integrated testing and certification system designed for both medium- and long-distance bidirectional validation of hollow core fiber (HCF). The solution combines VIAVI’s advanced 8100 Series OTDR modules, optical dispersion measurement (ODM) technology, and ReportPRO software, which incorporates specialized algorithms to support the bidirectional OTDR analysis required for HCF networks.

The performance and reliability of the solution have been demonstrated through extensive validation trials conducted in collaboration with fiber manufacturers, specialist installation partners, and three major hyperscale operators.

Compared with conventional single-mode fiber, hollow core fiber delivers up to 30% lower latency, as much as 70% less chromatic dispersion, approximately 65% lower attenuation, and reduced signal distortion. These characteristics allow higher-speed data transmission over longer distances with fewer amplification requirements and minimal signal loss or errors.

Adoption of hollow core fiber is accelerating, particularly for data center interconnects between hyperscale campuses, as well as applications such as artificial intelligence workloads, high-frequency trading, quantum communications, defense, and other use cases that demand significant improvements in operational and service performance.

HCF deployments typically involve higher capital investment and more complex testing requirements due to increased manufacturing costs, specialized installation processes, and unique optical behaviors such as altered backscattering and broader spectral ranges. To safeguard these investments and ensure long-term performance—especially across medium- and long-haul links—comprehensive testing is required, including bidirectional OTDR at higher wavelengths, dispersion measurements, and attenuation profiling. However, available testing and certification solutions are limited, and systems lacking sufficient OTDR performance or relying on OTDR-based dispersion techniques are often restricted to shorter distances.

VIAVI’s offering is the first unified certification solution capable of performing bidirectional OTDR, polarization mode dispersion (PMD), chromatic dispersion (CD), and attenuation profile (AP) testing with full reporting for hollow core fiber links. Leveraging industry-leading OTDR dynamic range and non-OTDR-based dispersion measurement methods, the solution supports all HCF types—including DNANF and PBG—across short, medium, and long-reach deployments. The solution is delivered via VIAVI’s OneAdvisor 800 Fiber platform.

“Hollow core fiber enables faster data transmission over longer distances, but validating splice quality, connector loss, and overall fiber integrity demands higher-performance and specialized test approaches,” said Kevin Oliver, Vice President and General Manager, Fiber and Access Solutions at VIAVI.

“Our all-in-one solution has demonstrated strong results across short-, mid-, and long-haul links during trials with leading fiber manufacturers and hyperscalers, helping customers protect their HCF investments and secure long-term returns.”
