According to a report published by OG Analysis, the global AI Data Center Coolant Distribution Unit (CDU) Market is estimated at USD 1.25 billion in 2026 and USD 1.57 billion in 2027. It is projected to reach USD 7.84 billion by 2034, expanding at a CAGR of 25.8% during 2026–2034. The full report, covering CDU configurations, cooling methods, end users, regional trends and competitive intelligence.

Market Overview: Liquid Cooling Infrastructure for AI Data Centers

Coolant distribution units (CDUs) manage coolant flow, temperature, pressure, filtration and heat exchange between facility cooling loops and liquid-cooled IT equipment. These systems support high-density GPU clusters, AI training facilities, hyperscale data centers, colocation facilities, enterprise computing and high-performance computing installations. In-row, rack-mounted, in-rack, floor-mounted, modular and facility-scale configurations help operators deploy thermal management close to increasingly powerful processors and server racks.

Expansion of AI computing capacity and rising rack power density are accelerating adoption of direct-to-chip and hybrid liquid cooling. Suppliers are improving CDU cooling capacity, redundancy, intelligent controls, leak detection, interoperability and integration with manifolds, cold plates and monitoring platforms. However, high capital costs, retrofit complexity, supply-chain constraints, liquid-cooling skills shortages and evolving standards remain important barriers to rapid adoption.
