Trane Technologies Expands System Architecture with Two New AI Factory Reference Designs Based on NVIDIA DSX AI Factory Platform

SWORDS, Ireland, September 28, 2026--Trane Technologies (NYSE: TT), a global climate innovator, today announced the expansion of its data center thermal management system portfolio with two new 250-megawatt (MW) high-density AI factory reference designs, based on the NVIDIA DSX AI Factory platform, that deliver high energy efficiency and zero water consumption cooling architectures.

The new reference designs build upon Trane Technologies' industry-first thermal management system reference design for gigawatt-scale AI factories and add technologies from recently acquired companies LiquidStack™ and Stellar Energy. The new 250 MW blueprints deliver zero water consumption cooling architectures that maximize Token per Watt and reclaim significant electrical capacity for compute workloads. They also introduce Trane Technologies' first reference design featuring Stellar Energy modular cooling plants, which help reduce time on the job site.

Additionally, the LiquidStack GigaModular Coolant Distribution Unit (CDU) platform integrated across both reference designs has qualified as an NVIDIA DSX Ready CDU, meeting applicable NVIDIA DSX reference design requirements for liquid-cooled AI infrastructure.

"When Trane Technologies introduced the industry's first comprehensive thermal management reference design for gigawatt-scale AI factories, we set a new standard for holistic system efficiency across compute, facilities and climate systems," said Mauro J. Atalla, Senior Vice President and Chief Technology and Sustainability Officer, Trane Technologies. "With our latest designs, we are incorporating new technologies and improvements that help data center developers overcome skilled labor shortages, compress deployment timelines and reclaim critical power for AI factories."

"Efficiently scaling gigawatt-scale AI factories demands tightly coordinated power, cooling and compute infrastructure that operates as one unified system," said Vladimir Troy, Vice President of AI Infrastructure at NVIDIA. "Trane Technologies' new cooling reference designs incorporate LiquidStack's GigaModular CDU, which has received the NVIDIA DSX Ready qualification. These new modular reference designs reduce integration risk, accelerate deployment and help operators maximize useful AI compute within available power, cooling and grid constraints."

As a Power and Cooling NVIDIA Partner Network program member, Trane Technologies has expanded its reference design portfolio with two additional high-efficiency solutions for large-scale AI deployments and the qualification of the LiquidStack GigaModular CDU as NVIDIA DSX Ready:
