Rack Cooling Manifolds Market Size to Reach $2.3 Billion by 2035

Rack cooling manifolds market is projected to grow from $893.3 million in 2025 and is projected to reach $2,347.8 million by 2035, growing at a CAGR of 10.2% during the forecast period 2026-2035. The increasing density of AI and accelerated computing infrastructure is fundamentally changing thermal management requirements within data centers. Traditional air cooling becomes less suitable as processors and accelerators generate concentrated heat at the rack level. Direct liquid cooling addresses this challenge by transferring heat from processors through circulating coolant and cold plates. Rack manifolds serve as the distribution point that connects these server-level cooling loops with the broader liquid cooling infrastructure. Their design therefore has a direct influence on flow balance, pressure management, serviceability, and system reliability. Demand is increasing for manifolds that can accommodate different rack heights and server configurations without requiring extensive redesign. Quick-disconnect technologies are also becoming more important because operators need to remove or replace servers without extensive disruption to surrounding infrastructure. Suppliers are consequently emphasizing standardized interfaces alongside configurable layouts. Stainless steel remains an important material because of its durability and compatibility with demanding cooling environments. At the same time, engineered polymers are gaining attention because they can provide corrosion resistance and support high-purity coolant environments. These developments are expanding the technical requirements placed on rack cooling manifold manufacturers.

Another major driver is the expansion of hyperscale, cloud, colocation, and AI-focused data center capacity. New facilities are increasingly being designed around higher rack densities, which is encouraging liquid cooling to become part of the initial infrastructure design rather than an afterthought. This is supporting demand for modular manifolds that can be integrated with CDUs, cold plates, piping networks, valves, sensors, and other fluid management components. Retrofit activity is also important because existing data centers are being upgraded to support newer GPU and accelerator platforms. Flexible manifold configurations allow operators to adapt cooling distribution systems to different rack arrangements and supply orientations. Prefabrication is gaining importance because it can reduce on-site assembly requirements and simplify deployment within constrained data center environments. Flow optimization is another area of development, with manufacturers focusing on reducing pressure losses and maintaining uniform coolant distribution across multiple outlets. Reliability requirements are particularly stringent because a manifold failure can affect several server cooling loops simultaneously. Consequently, leak prevention, connection integrity, corrosion resistance, and testing are becoming important design considerations. The growing emphasis on efficient thermal management is expected to sustain demand for advanced rack-level liquid distribution infrastructure.

Competitive Landscape of the Rack Cooling Manifolds Market

The key players in the rack cooling manifolds market are CoolIT Systems, Vertiv Group Corporation, Parker Hannifin Corporation, nVent Electric plc, and Georg Fischer Ltd., among others. The competitive landscape is characterized by a combination of specialized liquid cooling companies, data center infrastructure providers, fluid management manufacturers, and thermal engineering suppliers. Competition is increasingly centered on manifold reliability, flow balancing, connection technology, customization, and compatibility with emerging server architectures. Product development is also moving toward integrated liquid cooling ecosystems rather than standalone distribution components. Companies are expanding capabilities in direct-to-chip cooling, modular rack infrastructure, engineered polymers, quick-disconnect systems, and prefabricated fluid networks. This is creating a market where engineering capability and integration with broader cooling infrastructure are important competitive factors.

• In November 2025, nVent Electric plc announced an expanded portfolio of modular liquid cooling solutions for data centers at SC25. The launch included advanced technology cooling system manifolds, along with new rack-based and row-based coolant distribution units. The manifold expansion was specifically developed to align with current and future chip cooling requirements for AI and high-performance computing infrastructure. Since manifolds are a core component used to distribute coolant between CDUs and server cooling loops, this product expansion directly targets the rack cooling manifolds market and reflects increasing industry investment in liquid-cooled rack infrastructure.
