Flex Introduces a Revolutionary Cooling Solution

Flex, a prominent leader in manufacturing and innovation, recently launched its Modular Rack-Level Cooling Distribution Unit (CDU). This unit represents a significant step forward in cooling technology that is essential for today’s data centers. As demands for AI, high-performance computing (HPC), and hyperscale workloads continue to surge globally, the need for efficient cooling solutions has never been more critical.

Overview of the Modular Rack-Level CDU

Scalable and Efficient

The newly introduced Modular Rack-Level CDU provides a flexible solution with a scalable architecture, designed to accommodate between 2 and 6 individual CDUs per rack. This allows for a remarkable cooling capacity ranging from 600 kW to 1.8 MW, enabling data center operators to start with a manageable capacity and expand as needed without significant physical restructures. The modular design ensures that the cooling system can adapt in real-time to the evolving power demands of computing technologies.

Key Features

• - Scalability: Adjust between 2 to 6 CDUs per rack for customizable cooling.
• - Flexible Thermal Loading: Operates efficiently at a rate of 1–1.5 LPM/kW, accommodating various hardware.
• - Space Efficiency: It maximizes cooling performance while preserving valuable rack space, crucial for high-density configurations.
• - Integrated Deployment: Capable of supporting diverse configurations of CDUs, servers, and storage systems, thanks to its intelligent design.
• - Energy Optimization: Matches cooling output precisely to the demand, significantly reducing energy waste and lowering operating costs for clients.

Addressing Current Challenges

In an era where every watt counts, Flex’s CDU helps data center managers meet the challenges of efficient cooling without incurring substantial operational costs. The traditional cooling methods are often outdated, and modifying these systems can lead to disruptions. Flex's Modular Rack-Level CDU is designed to seamlessly integrate into existing setups and provide immediate scalability, enhancing operational efficiency.

A Vertically Integrated Approach

Flex’s comprehensive liquid cooling portfolio emphasizes streamlined integration and operational simplicity. By overseeing the design, manufacturing, and deployment processes from start to finish, Flex can ensure high-quality, consistent products while reducing the complexity of vendor management for its clients. “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 Flex’s Communications, Enterprise, and Cloud Business. This vertically-integrated strategy allows faster responses to market demands and ensures fewer risks during deployment.

Commitment to Customers

Flex backs this integrated solution with robust warranty and global support options. Designing, validating, and manufacturing all components in-house means clients can expect swift deployments with minimal vendor interactions. This empowers customers to move from the planning phase to implementation that much faster, minimizing downtime.

Availability

The Modular Rack-Level CDU is currently available for immediate distribution, appealing to data center operators eager for scalable liquid cooling solutions. Operators can choose from standard and custom manifolding options. Additionally, an in-row-CDU is scheduled to launch in April 2026, further expanding Flex’s capabilities in the data cooling market.

Conclusion

For facilities looking to deploy cutting-edge cooling systems that can grow with their needs, Flex’s new Modular Rack-Level Cooling Distribution Unit offers an ideal solution. As the demand for efficient and scalable cooling solutions escalates, Flex continues to lead the charge in creating innovative products that transform data center operations.
