The data center coolant distribution units market covers products that control and distribute liquid coolants so that high-performance servers and IT systems operate at the right temperature. Polaris Market Research values the market at USD 1.04 billion in 2025, with a 2026 estimate of USD 1.39 billion and a projection of USD 13.95 billion by 2034 at a CAGR of 33.39%. Smart monitoring, power-efficient designs, and modular architectures are improving performance and making data center operations more sustainable.

Cooling Technology and Sustainability

Interest in direct-to-chip liquid cooling is rising because coolant is directed into processors, GPUs, and other heat-generating components, so heat is removed at the source. The report says the approach is used extensively in AI servers, HPC systems, and hyperscale facilities, where it stabilizes temperatures and reduces the cooling burden on existing equipment.

CDUs also contribute to energy savings by making liquid cooling more effective. Facilities therefore need less energy to cool servers and IT infrastructure, which supports power usage effectiveness, a critical measure of data center efficiency. Effective cooling also prevents overheating and can increase server durability.

The report's comparison is instructive. Liquid cooling can save on cooling expenses in the long run, while air cooling lowers initial expenses but incurs higher power costs because fans rotate constantly.

Choosing Between CDU Formats

Polaris compares three main formats. The in-rack CDU is integrated at the bottom of a rack, fits a standard 19-inch rack at 8U, and provides compact, localized thermal control. It is used in edge computing, telecom, storage, and modular or single-rack deployments.

The floor-mounted CDU is mounted on or under the data center floor and usually relies on a liquid-to-liquid design with the facility water loop. It needs a larger footprint but handles large heat loads and suits data centers with existing water infrastructure, and the report notes stable growth in large establishments.

Edge Computing and Application Reach

Edge data centers are smaller facilities built closer to consumers to reduce latency. Space is limited, yet the high-performance computers inside still need proper cooling, and CDUs offer an efficient way to provide it. These sites support applications such as 5G, IoT, autonomous vehicles, and real-time computing.

By application, industrial cooling is projected to register a CAGR of 18.4%, driven by liquid cooling in industrial automation and semiconductor manufacturing. By capacity, the 100–500 kW segment held the highest share in 2025, while systems above 500 kW are expected to grow fastest. Europe also holds a significant share, supported by EU carbon neutrality and energy efficiency regulations.

By end user, IT & telecom dominated in 2025, driven by huge data traffic and cloud penetration, while healthcare is estimated to grow rapidly because of rising demand for high-performance computing infrastructure that supports medical data and AI-based diagnostic systems.

By distribution channel, direct sales held a significant share in 2025 because large operators want customized system design and integration. Distributors and resellers are expected to grow rapidly as small and medium-sized facilities seek cost-efficient, easy-to-deploy solutions.

Looking ahead, Polaris expects investments in hyperscale and edge computing to keep opening avenues for growth, with higher server rack density and wider adoption of liquid cooling continuing to drive the market.
