Sabey Data Centers is adding OptiCool Technologies to its growing ecosystem of advanced cooling partners, aiming to make high-density and AI-driven compute deployments more practical and energy efficient across its U.S. footprint. This move highlights how colocation providers are turning to specialized liquid and refrigerant-based solutions as rack densities outstrip the capabilities of traditional air cooling.

OptiCool is known for two-phase refrigerant pumped systems that use a non-conductive refrigerant to absorb heat through phase change at the rack level. This approach enables efficient heat removal without chilled water loops or extensive mechanical plant build-outs, which can simplify facility design and cut both capital and operating costs for data centers pushing into higher power densities. Sabey is positioning the OptiCool alliance as part of its integrated cooling technologies partnership program, which is designed to lower barriers to liquid and alternative cooling adoption for customers. Instead of forcing enterprises to engineer bespoke solutions for each deployment, Sabey is curating pre-vetted architectures and partners that align cooling technology, facility infrastructure and operational responsibility. For operators planning AI and HPC rollouts, that can translate into clearer deployment paths and reduced integration risk.

The appeal of two-phase refrigerant cooling lies in its combination of density, efficiency and retrofit friendliness. Because the systems move heat directly from the rack to localized condensers using a pumped refrigerant, they can often be deployed with minimal disruption to existing white space. That makes them attractive for operators that need to increase rack power without rebuilding entire data halls or adding large amounts of chilled water infrastructure.

Sabey executives frame the partnership as a response to customer demand for flexible, future-ready cooling options. As more organizations standardize on GPU-rich architectures and high-density configurations, cooling strategy has become a primary constraint on capacity planning. By incorporating OptiCool’s technology into its program, Sabey is signaling to customers that they will have multiple, validated pathways to support emerging workload profiles while staying within power and sustainability envelopes.

As liquid and refrigerant-based cooling rapidly move into the mainstream, customers evaluating their own AI and high-density strategies may benefit from understanding how Sabey is standardizing these technologies across its portfolio.
