Flex, a global manufacturing leader and innovator in data center infrastructure solutions, has recently launched 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 specialising 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.
As AI, HPC, and hyperscale workloads surge, data centres 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.
Flex’s liquid cooling portfolio is built for scalable integration and operational simplicity – delivering a comprehensive, end-to-end solution for today’s data centre 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.
