Motivair by Schneider Electric has introduced the MCDU-70, a 2.5MW coolant distribution unit (CDU) designed to support high-density cooling requirements in large-scale data centres, including AI and accelerated computing environments.

The MCDU-70 is the highest-capacity CDU in Motivair’s portfolio and is aimed at meeting the demands of next-generation GPU-based workloads and emerging AI Factory designs. Using Schneider Electric’s EcoStruxure software, the CDU operates as part of a centralised liquid cooling system that can scale beyond 10MW, supporting future high-performance computing and AI deployments.

Designed for large facilities targeting multi-megawatt capacity, the MCDU-70 aligns with data centre architectures such as NVIDIA Omniverse DSX Blueprint, where installations are designed to scale toward gW-class infrastructure. At 2.5MW per unit, multiple MCDU-70s can be deployed to support 4+2 redundancy configurations while remaining compatible with NVIDIA’s current and projected GPU roadmap.

As GPU-powered AI workloads generate significantly more heat than traditional CPU-based systems, liquid cooling has become essential for managing rack power densities projected to reach 1MW and beyond. Motivair’s CDU range is designed to address these challenges through modular and custom-built solutions tailored to site-specific capacity requirements.

“Data centre success now hinges on delivering scalable, reliable and efficient infrastructure that can keep pace with rapid chip evolution. The MCDU-70 is designed to scale with our customers as AI Factory deployments continue to grow,” Motivair by Schneider Electric chief executive Rich Whitmore says.

With the addition of the MCDU-70, Schneider Electric’s liquid cooling portfolio now spans 105kW to 2.5MW CDUs, offering scalable building blocks for a wide range of data centre designs. The MCDU-70 features a compact footprint, dual heat exchangers, parallel filtration and maintains the industry target of 1.5L per minute per kW, while preserving full flow performance and minimising system pressure drop.
