The In-Row CDU delivers efficient liquid cooling through a modular architecture that supports seamless capacity expansion as workloads grow. Deployed within the IT row, it enables a phased CAPEX strategy, allowing data center operators to start small and scale progressively without major infrastructure changes. Built-in redundancy is available at both the component level (such as pumps and controls) and the system level, ensuring high availability and operational resilience. This flexible approach minimizes overprovisioning, optimizes cash flow, and provides a future-ready cooling solution for AI and high-performance computing applications.
