LiquidStack, a Trane Technologies company and global leader in liquid cooling technologies for data centers, today announced the commercial availability of its GigaModular™ CDU platform. The platform’s modular, pay-as-you-grow architecture, designed to meet NVIDIA Vera Rubin specifications, enables AI data center operators to deploy liquid cooling infrastructure with greater speed, flexibility and operational simplicity through multi-MW building blocks that scale up to 14 MW.
“Purpose-built for high-density AI environments, GigaModular™ helps operators expand cooling capacity without requiring significant infrastructure redesigns or over-provisioning upfront,” said Joe Capes, Vice President at Trane Technologies and General Manager of LiquidStack™. “Its flexible deployment and distribution architecture enables phased buildouts aligned to AI compute demand, while centralized system-level controls help simplify operations, improve efficiency and optimize capital planning.”
The GigaModular™ CDU platform supports the demands of both merchant silicon and hyperscale custom silicon heat profiles across application temperature ranges, giving operators greater flexibility as compute and thermal requirements evolve.
Designed for AI, HPC, and hyperscale data centers, the platform offers:
-
Centralized control to simplify operations, reduce redundancy and improve infrastructure efficiency at scale.
-
System-level scalability to support coordinated AI infrastructure expansion rather than aggregated independent CDU capacity.
-
Flexible deployment and distribution architecture that adapts to evolving AI workloads, rack densities, and facility layouts.
-
Pay-as-you-grow modular building blocks allowing operators to scale AI capacity incrementally without major infrastructure redesigns.
-
Future-ready support for next-generation GPU platforms in high-density environments and gigawatt-scale deployments.
-
Integrated with Trane Technologies’ broader thermal management offering, combining advanced CDU technology with global service support across deployment and the full equipment lifecycle.
First announced in June 2025, the GigaModular™ CDU has completed extensive multi-module system integration and full-load testing, validating performance of deployments up to 14 MW and achieving ETL certification. The platform is now commercially available, with early customer orders reflecting market demand for scalable liquid cooling infrastructure.
LiquidStack™ will showcase GigaModular™ at Datacloud Global Congress, June 2–4 at the Palais des Festivals in Cannes, France, including live VR demonstrations of the platform. Attendees can visit LiquidStack at Booth #109.
