Flex Launches Modular Rack-Level Cooling Solution for Advanced Data Center Efficiency

Flex Unveils Innovative Cooling Solution for Data Centers

Flex (NASDAQ: FLEX), a prominent player in manufacturing and data center infrastructure solutions, introduces its new Modular Rack-Level Cooling Distribution Unit (CDU) in a significant development for the industry. Launched on September 23, 2025, in Austin, Texas, this advanced CDU is designed to meet the growing demands of artificial intelligence (AI), high-performance computing (HPC), and hyperscale workloads. With the ability to provide flexible cooling capacity of up to 1.8 megawatts (MW), the Modular Rack-Level CDU enables data centers to enhance their cooling capabilities without major overhauls or excessive energy consumption, addressing a pressing need in today’s technology landscape.

The innovative design of the Modular Rack-Level CDU features a scalable architecture that allows for the deployment of between 2 to 6 CDUs per rack, delivering cooling capacities ranging from 600 kW to 1.8 MW. This scalable approach not only optimizes space utilization but also maximizes compute density, catering to a variety of hardware setups. Operating at a thermal loading range of 1 to 1.5 liters per minute per kilowatt, the CDU is adept at accommodating diverse cooling needs, ensuring that data centers remain efficient and responsive to varying workloads. This flexibility is critical as organizations increasingly rely on advanced technologies that demand higher cooling performance.

Rob Campbell, President of Communications, Enterprise, and Cloud Business at Flex, underscores the significance of this launch. He emphasizes that the Modular Rack-Level CDU provides customers with the scalability, efficiency, and simplicity essential for navigating the current challenges faced by data centers. Flex's vertically integrated approach to its liquid cooling portfolio enhances operational simplicity and reduces vendor complexity, facilitating a quicker time-to-market while maintaining consistent quality. This strategic initiative not only addresses immediate cooling needs but also positions Flex for future growth in a rapidly evolving market, with plans for a dedicated in-row CDU set to be released in April 2026.

In addition to the CDU launch, Flex continues to focus on enhancing its liquid cooling solutions as the demand for efficient and scalable infrastructure grows. The company’s commitment to innovation in this area is crucial for supporting the evolving landscape of data management and processing. As organizations increasingly adopt advanced computing technologies, solutions like the Modular Rack-Level CDU are poised to play a pivotal role in shaping the future of data center operations.
