Flex Launches Modular Rack-Level Cooling Unit for Data Centers

Sep 23, 2025
Flex has introduced a new Modular Rack-Level Cooling Distribution Unit, offering scalable cooling solutions for AI and HPC workloads, announced in a press release.

Flex has launched a new Modular Rack-Level Cooling Distribution Unit (CDU), announced in a press release. This scalable solution is designed to meet the growing demands of AI, high-performance computing (HPC), and hyperscale workloads, providing flexible capacity up to 1.8 megawatts (MW).

Developed by JetCool, a company under Flex, the Modular Rack-Level CDU allows data center operators to start with a smaller setup and expand as needed, supporting 2 to 6 CDUs per rack. This design not only preserves rack space but also maximizes compute density per floor tile.

The CDU's features include flexible thermal loading and integrated deployment options, which support mixed configurations of CDUs, servers, and storage. It also optimizes energy use by matching cooling output to demand, reducing waste and lowering operating costs.

The Modular Rack-Level CDU is available immediately, with plans to expand the portfolio further with an in-row-CDU set for release in April 2026.
