Rockville, MD., September 19, 2026 — The global coolant distribution units market is projected to reach USD 6,976.8 million by 2036, up from USD 1,032.5 million in 2026, expanding at a 21.10% CAGR, according to Fact.MR. The market is being shaped by higher rack power densities, AI workloads, high-performance computing, and the shift from conventional air cooling toward liquid cooling in data centers.

The immediate question for data center operators is how to manage rising heat loads without allowing cooling requirements to erode energy efficiency. Fact.MR identifies liquid cooling as increasingly relevant where rack power densities reach 30 to 80 kW per rack, making conventional air cooling less efficient for dense AI and HPC environments.

AI workloads accelerate demand for liquid cooling

The expansion of artificial intelligence is changing the thermal requirements of computing infrastructure. AI accelerators and high-performance GPUs generate concentrated heat loads that can exceed the practical limits of conventional air-based systems.

Fact.MR identifies the rapid deployment of AI accelerators and HPC clusters as a direct driver of CDU demand. Data center operators are adopting liquid cooling to maintain temperature control while supporting higher computing density.

The report points to a specific industry development. In March 2024, Vertiv introduced the Vertiv CoolChip CDU 70, designed for high-density AI and HPC applications and scalable direct-to-chip liquid cooling integration.

Extractable fact: A coolant distribution unit is a cooling system that pumps, filters, monitors, and regulates temperature-controlled liquid through servers, racks, or direct-to-chip cooling loops.

Fact.MR states that long-term market leadership will depend on suppliers' ability to integrate high-efficiency liquid cooling into hyperscale and AI-driven data center architectures while maintaining modular scalability and competitive total cost of ownership.

Energy-efficiency rules support CDU adoption

Energy consumption is another factor influencing cooling architecture decisions. The European Union Energy Efficiency Directive and regional data center sustainability guidelines are encouraging operators to reduce power use and improve facility efficiency.

CDUs support closed-loop liquid cooling architectures. These systems can improve thermal management while reducing the energy intensity associated with cooling high-density computing equipment.

Schneider Electric expanded its liquid cooling portfolio in April 2024, integrating rack-based CDU systems with EcoStruxure monitoring for AI-ready data centers, according to Fact.MR.

The market also faces constraints. High upfront investment, integration difficulties in existing air-cooled facilities, coolant-loop expertise requirements, corrosion risks, fluid compatibility, and maintenance requirements can slow deployment.

India records 26.9% CAGR through 2036

India is projected to record the fastest growth among the countries listed by Fact.MR, with the coolant distribution units market expanding at a 26.9% CAGR from 2026 to 2036. Rising data center construction, cloud infrastructure expansion, and digital transformation are supporting demand.

China follows at 21.5% CAGR, supported by investment in AI infrastructure and hyperscale data centers. The report identifies the government-backed Eastern Data, Western Computing project as a factor supporting energy-efficient data center development.

Germany is projected to expand at 21.4% CAGR, while France records 22.7%. Saudi Arabia is expected to grow at 23.2%, reflecting increasing digital infrastructure investment and smart-city development. Indonesia is projected to expand at 22.4% CAGR as colocation facilities and cloud adoption increase.

The United States remains a major market, with Fact.MR projecting a 19.3% CAGR through 2036. Hyperscale data center expansion, AI infrastructure, and early liquid-cooling adoption are supporting the market.

HPC creates demand for high-capacity thermal management

High-performance computing is a major application area for coolant distribution units. Scientific research centers, defense computing clusters, weather modeling systems, and genomics facilities require precise thermal management because dense computing workloads generate substantial heat.

In May 2024, CoolIT Systems partnered with Dell Technologies to deploy direct-to-chip liquid cooling integrated with Dell PowerEdge servers for AI and HPC workloads, according to the Fact.MR report.

Recent developments show continued investment in higher-capacity systems. In September 2025, Johnson Controls, through its Silent-Aire brand, introduced a CDU platform ranging from 500 kW to more than 10 MW. In November 2025, ZutaCore unveiled 1.2 MW and 2 MW Waterless End-of-Row CDU systems for AI and hyperscale data centers.

Competitive landscape focuses on scalable cooling
