LOUIS, MO, Apr 27, 2026 – Belden and OptiCool are targeting a key constraint in AI data center deployment: cooling high-density racks without rebuilding the facility. The companies are integrating OptiCool heat exchangers with Belden racks and cabinets to deliver cooling directly at the rack level. The configuration supports AI workloads in new and existing facilities while combining racks, power, connectivity and cooling into one deployable package.
OptiCool heat exchangers remove heat from high-density computing systems at the rack level. This approach reduces the need for separate infrastructure design and integration required for AI-ready deployments.
The configuration supports up to 120 kW per rack. It is designed for high-density data center environments where AI systems increase heat loads at the rack level.
“AI is changing what data centers need to deliver, but it shouldn’t always require a ground-up rebuild,” said Belden global vertical leader for data centers Brian Kennedy. “By pairing our racks, power and connectivity with OptiCool’s rear‑door heat exchangers, we give operators a practical way to turn existing white space into AI‑ready capacity, without disrupting their current environment. These solutions are designed to work with any server, storage and networking approach operators choose.”
“Our partnership with Belden is a foundational step in delivering the more complete solutions customers need as they plan for higher-density AI workloads,” says OptiCool VP of sales, Matt Roberts. “By combining Belden’s rack infrastructure with OptiCool’s two-phase rear-door cooling technology, we can help simplify deployment, reduce integration challenges and support the next generation of data center environments.”
Available through channel partners, including OptiCool’s agent network and distributors, as well as Belden’s channel ecosystem, data center teams can source, configure and deploy these solutions through the same providers they already use for critical infrastructure.
