- New coolant distribution unit, the WCDU, is designed for a wide-range of configurations and optimized to meet the need for high-capacity technical corridor-based cooling architectures
- Seamless integration with air cooling configurations and multiple installation options give operators greater flexibility
- Single WCDU provides cooling capacity up to 3.5MW, with an accessible design for simplified high-density deployment in space-constrained environments
- Supports approach temperature differences as low as 2 °C to improve PUE and reduce OpEx for the entire cooling system

RUEIL-MALMAISON, France, Sept. 23, 2026 (GLOBE NEWSWIRE) — Schneider Electric, a global energy technology leader, today launched its WCDU, a coolant distribution unit suitable for a wide range of configurations and is designed for seamless integration with fan wall air-cooling systems to support hybrid air and liquid cooling architectures in high-density AI data centers. Designed for greater deployment flexibility, the unit allows operators to adjust the balance of liquid and air cooling without fully redesigning the data hall. This approach allows for versatility as workloads are finalized to avoid overbuilt infrastructure and stranded capacity.

The new WCDU reflects the evolution of liquid cooling and matches changing infrastructure deployments for the AI era. Large data centers operators are increasingly deploying CDUs outside of the white space in the technical corridor for easier service and maintenance. The WCDU is optimized for the technical corridor and equipped with top entry connections to reduce installation complexity and keep the white space clear, which simplifies installation and service access.

“As the only CDU that brings together both liquid and air cooling within a single solution, we’re delivering a level of flexibility the market hasn’t seen before,” said Andrew Bradner, Senior Vice President of the Cooling Business at Schneider Electric. “This approach allows operators to deploy more efficiently, support a wider range of liquid cooling infrastructure configurations, and significantly reduce time to deployment.”

The new addition complements, expands and strengthens the Motivair by Schneider Electric line of liquid cooling solutions, which includes a range of CDUs to match a broad range of row-based, corridor-based and other deployment architectures.

Additional Key Benefits of the WCDU
Article content
The WCDU’s all-in-one design, which incorporates Integrated pumps, heat exchangers and other critical CDU components into a single steel frame, simplifies deployment and provides multiple installation options through a scalable, multi-modal architecture. In addition to integrating with fan walls, the WCDU can be used as a standalone unit. As a result, operators currently using fan walls for their cooling infrastructure gain an easier path to retrofitting their facilities. The unit also maintains zero lateral clearance, enabling optimized density in existing and new data hall layouts. The WCDU also supports:
