OptiCool has introduced the industry’s highest-capacity rear door heat exchanger, delivering 120kW of cooling power, specifically designed for the demanding thermal needs of AI and high-performance computing (HPC) workloads. The new 120kW Rear Door Heat Exchanger (RDHx) is engineered to support the extreme heat densities generated by modern AI servers and data center infrastructure, enabling more efficient and scalable cooling solutions. Built for ease of deployment, the system is retrofit-ready, allowing data center operators to upgrade cooling capacity without major infrastructure overhauls. This makes it an ideal solution for existing facilities looking to future-proof their operations as AI workloads continue to grow in intensity and scale. The advanced design of the 120kW RDHx maximizes heat transfer efficiency while minimizing energy consumption, helping data centers reduce their overall power usage effectiveness (PUE). By capturing heat directly at the source—on the rear of server racks—the system prevents hot air recirculation and improves airflow management, contributing to more stable and reliable operations. OptiCool’s new offering is part of a broader push to address the escalating thermal challenges posed by AI and HPC systems, where traditional cooling methods are increasingly inadequate. With AI models requiring more compute power and generating significantly higher heat outputs, the demand for high-capacity, precision cooling solutions has surged. The company emphasizes that the 120kW RDHx is not only powerful but also modular and scalable, allowing data center operators to deploy multiple units in a single rack or across entire server halls to meet evolving cooling demands. Its compact footprint and compatibility with existing rack configurations make it a practical choice for both new builds and upgrades. As AI and HPC continue to drive innovation across industries—from healthcare and finance to autonomous systems—efficient thermal management has become a critical factor in maintaining performance, reliability, and sustainability. OptiCool’s latest RDHx solution positions data centers to meet these challenges head-on, offering a high-capacity, energy-efficient, and future-ready cooling option.
