Market Segmentation 

The global data center cooling market share is classified into Cooling System Type, Application, and Cooling Technology.

• The CRAC/CRAH Units segment dominated the market and holds approximately 31% share in 2025 and is projected to grow at a substantial CAGR during the forecast period.

Based on cooling system type, the global data center cooling market is divided into CRAC/CRAH Units, chiller units, cooling towers, heat exchangers, and others. Among these, CRAC/CRAH units dominate because they remain widely deployed in conventional enterprise, colocation, and hyperscale facilities. They provide precise temperature and humidity control and can be integrated with raised-floor and contained-airflow architectures. Their established installed base and relatively straightforward maintenance continue to support demand, even as liquid cooling gains importance in high-density AI environments.

• The Hyperscale Data Centers segment accounted for the largest share of approximately 42% in 2025 and is anticipated to grow at a significant CAGR during the forecast period.

Based on Application, the market is divided into Hyperscale Data Centers, Colocation Data Centers, Enterprise Data Centers, and Edge Data Centers. Among these, Hyperscale Data Centers accounted for the largest share and hold approximately 42% share in 2025. Hyperscale operators are rapidly expanding AI and cloud infrastructure, requiring high-capacity cooling systems capable of handling substantial rack densities. The increasing deployment of GPU clusters and accelerated-computing platforms is encouraging hyperscalers to adopt liquid cooling and hybrid thermal architectures. Continuous investment by cloud and technology companies is therefore expected to maintain the segment's leading position.

• The Air-Based Cooling segment accounted for the largest share of approximately 62% in 2025 and is anticipated to grow at a significant CAGR during the forecast period.

Based on Cooling Technology, the market is divided into Air-Based Cooling, Direct-to-Chip Liquid Cooling, Immersion Cooling, and Hybrid Cooling. Among these, Air-Based Cooling dominates because it has the largest installed base and remains economical for conventional and medium-density workloads. CRAC/CRAH systems, chillers, cooling towers, and containment technologies are widely understood by data-center operators. However, Direct-to-Chip Liquid Cooling is expected to register faster growth because AI and HPC workloads increasingly exceed the practical thermal limits of traditional air cooling.
