OptiCool Technologies has launched its new 120kW Rear Door Heat Exchanger( RDHx) – the highestcapacity rear door heat exchanger( RDHx) on the market. Capable of removing up to 120kW per rack, it’ s purpose-built to meet the extreme thermal demands of nextgeneration AI and HPC workloads. Engineered for seamless retrofit into existing environments, the new 120kW Rear Door Heat Exchanger – the highest-capacity unit of its kind – supports rack densities of up to 120kW and removes the need for separate zones or major infrastructure overhauls. Its proprietary two-phase refrigerant design, based on the thermodynamics of phase change, removes heat from the rack and returns it into the space at room |
neutral ambient temperature. This launch expands OptiCool’ s existing RDHx lineup( 30kW and 60kW), delivering a modular, high-capacity option for operators balancing density, uptime, and energy use. OptiCool’ s Rear Door Heat Exchanger system requires significantly less energy than traditional air-based cooling approaches, helping operators reduce cooling costs and improve energy efficiency. The 120kW Rear Door Heat Exchanger leverages the same ultra-efficient design principles as OptiCool’ s lowercapacity units, which have achieved power usage effectiveness( PUE) as low as 1.02 in tested deployments. This helps data centers advance ESG goals while preparing for nextgeneration compute demands. |
Johnson Controls( JCI) has expanded its data center thermal management offerings with the launch of its Silent-Aire Coolant Distribution Unit( CDU) platform. This latest addition to Johnson Controls’ end-to-end thermal management portfolio enables data centers to seamlessly transition to liquid cooling as rack densities rise. The Silent-Aire CDUs offer a wide range of scalable cooling capacities from 500kW to over 10MW in flexible designs that are uniquely tailored to suit the needs of any data center deployment. With the rapid growth of AI and increasing demand for computing power, denser chips are generating more heat, making cooling innovation a critical priority. Silent-Aire CDUs allow for precision cooling of this equipment, enabling |
data center owners and operators to deploy the latest in semiconductor technology. Positioned either inrow adjacent to heat-generating equipment or in the whitespace perimeter, Silent-Aire CDUs are designed for flexibility to support a wide range of liquid-cooling configurations and hybrid designs to deliver precise, efficient cooling of high-performance environments ranging from edge-based inference to large AI factories. This launch builds on Johnson Controls’ broad portfolio of existing Silent-Aire, York, and M & M Carnot thermal management products that serve data centers worldwide. By adopting Johnson Controls’ comprehensive thermal management solutions, owners and operators can significantly improve total facility efficiency. |
