Flex Expands Data Center Cooling Portfolio with Launch of Modular Rack-Level Coolant Distribution Unit

New scalable solution delivers flexible capacity up to 1.8 megawatts (MW) to meet evolving AI, high performance computing (HPC), and hyperscale workloads.

AUSTIN, Texas, Sept. 23, 2025 /PRNewswire/ -- Flex (NASDAQ: FLEX), a global manufacturing leader and innovator in data center infrastructure solutions, today announced the launch of its new Modular Rack-Level Cooling Distribution Unit (CDU)—available immediately—as the latest addition to its expanding cooling portfolio. Developed by JetCool, a Flex company specializing in advanced liquid cooling technologies, this launch marks the first step in Flex's broader market coverage strategy for cooling distribution units, with a dedicated in-row-CDU scheduled for release in April 2026.

Modular Rack-Level CDU: Scalable, High-Performance Cooling

As AI, HPC, and hyperscale workloads surge, data centers need cooling solutions that keep pace without costly overhauls or wasted energy. Flex's Modular Rack-Level CDU meets this with a right-sized design that grows from 2 to 6 CDUs per rack—up to 1.8 MW—allowing operators to start small, add capacity incrementally, and adapt quickly while preserving rack space and efficiency.

 It's an ideal solution for facilities deploying liquid cooling today and expanding seamlessly to higher-capacity options.

Key Features & Benefits

• Scalable architecture: 2–6 CDUs per rack, delivering 600 kW to 1.8 MW of cooling capacity
• Flexible thermal loading: Operates at 1–1.5 LPM/kW to support varied hardware and workloads
• Space efficiency: Preserves rack space while maximizing compute density per floor tile
• Integrated deployment: Supports mixed configurations of CDUs, servers, and storage with intelligent manifolding
• Energy optimization: Matches cooling output to demand to reduce waste and lower operating costs

Value of a Vertically Integrated Solution

Flex's liquid cooling portfolio is built for scalable integration and operational simplicity – delivering a comprehensive, end-to-end solution for today's data center demands. By aligning key design elements across its CDU lineup and manufacturing them under one roof, Flex reduces vendor complexity, accelerates time-to-market, and ensures consistent quality. This vertically integrated approach also simplifies procurement and maintenance—helping operators deploy high-performance cooling faster and with fewer risks.

"With AI and high-performance computing driving unprecedented demand, customers need more than just capacity—they need a partner who can deliver scalability, efficiency, and simplicity across the entire cooling ecosystem," said Rob Campbell, President of Communications, Enterprise, and Cloud Business at Flex. "This launch reflects our end-to-end approach from design and manufacturing to deployment and support, providing a right-sized solution for today's challenges and a scalable foundation for tomorrow's growth."

Flex supports this integrated approach with comprehensive warranty and global support options. By designing, validating, and manufacturing all components in-house, the company enables faster deployments and fewer vendor touchpoints, helping customers move from planning to implementation with greater speed and confidence.

Timing & Availability

The Modular Rack-Level CDU is available now, providing data center operators with an immediate solution for scalable liquid cooling. Standard and custom manifolding options are available. Looking ahead, the company plans to expand its portfolio further with the launch of its dedicated in-row-CDU in April 2026.
