Global In-Row Coolant Distribution Units (CDU) Market Strategic Research Report

Scope of the Report

The global In-Row Coolant Distribution Units (CDU) market size is predicted to grow from US$ 541 million in 2025 to US$ 2,090 million in 2032; it is expected to grow at a CAGR of 21.3% from 2026 to 2032.

In-Row Coolant Distribution Units (CDUs) are full-sized systems designed to be installed alongside server racks, offering highly efficient cooling solutions for data centers. These units operate by circulating coolant through a closed-loop system on the secondary side, which is responsible for cooling the servers. The primary side of the CDU utilizes facility water to absorb and reject the heat generated by the servers. This separation between the coolant and facility water helps prevent contamination and enhances system reliability. By being located close to the heat source, In-Row CDUs can optimize cooling efficiency, reduce energy consumption, and ensure stable operating temperatures for critical IT infrastructure.

Upstream: The main components of a CDU include pumps, reservoirs, power supplies, control boards, and heat exchangers. Additionally, filters, flow meters, pressure transducers, and other devices are usedin managing the operation of the CDU in conjunction with the Server Rack. Downstream: CDUs are primarily used in data centers.

In 2025, global sales of In-Row Coolant Distribution Units reached approximately 17 K units, with an average global market price of around US$ 33 K/unit. Production capacity varies significantly among manufacturers, with gross profit margins ranging from approximately 30% to 50%.

Coolant distribution unit (CDU) is a system that enables smaller, more efficient, more precise liquid cooling in a data center at rack level, often integrating facility water. The CDU circulates coolant in a closed loop system within the rack on the secondary (Cooling Application) side and utilizes facility water on the primary (Heat Rejection) side. A CDU has a pump, reservoir, power supply, control board and a heat-exchanger as the key components. Filters, flow meters, pressure transducers, and other devices are also used in managing the operation of the CDU in conjunction with the Server Rack.

With data center workloads ever increasing due to advanced analytics, AI, and the digitization of every process, the average rack power draw has shot up considerably. And, as we know, with more power draw comes more waste heat that needs to be removed from the rack and eventually the white space. Based on this, liquid cooling technology is gradually replacing traditional air cooling technology to provide high performance solutions to data centers. As a key part of liquid cooling system, CDU will benefit from the permeability of liquid cooling in data centers accordingly.

As data center footprints continue to shrink due to urbanization and real estate constraints, optimizing space utilization has become a pressing priority for data center managers. Liquid cooling solutions offer a compact and space-efficient alternative to traditional air cooling systems, enabling data centers to maximize their rack densities and floor space without compromising thermal performance. Moreover, the scalability of liquid cooling systems makes them well-suited for accommodating future growth and expansion. By modularizing cooling infrastructure and deploying liquid cooling units in a distributed manner, data centers can easily scale their cooling capacity in response to changing workload demands. This flexibility not only enhances operational agility but also streamlines the deployment of new IT equipment without the need for extensive retrofitting or reconfiguration.
