WEBSTER, N.Y. — March 17, 2026 — OptiCool Technologies, a provider of advanced two-phase rear door heat exchanger (RDHx) cooling solutions for high-density compute environments, today announced a strategic solutions referral partnership with CoreSite, an American Tower company (NYSE: AMT) empowering critical business and AI workloads that impact everyday life through interconnected data center solutions. The partnership is designed to help customers deploying next-generation infrastructure in CoreSite facilities to address rising thermal constraints and power density requirements.
High-density deployments are moving from edge use cases to the new baseline, and cooling is now a deciding factor in what can be deployed, where, and how fast. Through this partnership, OptiCool and CoreSite will partner to streamline introductions and accelerate deployments where advanced cooling solutions are required—particularly for customers evaluating higher-density environments inside CoreSite data centers.
“This partnership is about helping customers move faster when cooling becomes a critical requirement,” said Lawrence “LL” Lee, Chief Channel Officer at OptiCool. “By aligning with CoreSite, we’re creating a clearer path for teams navigating thermal constraints and higher power densities, so they can evaluate options earlier and deploy with greater confidence.”
OptiCool is the leader in two-phase, close-coupled heat extraction systems, delivering high-performance liquid cooling without added complexity. As the leading provider of rear door heat exchangers (RDHx) built on a two-phase liquid refrigerant design, OptiCool helps data centers address rising heat loads and scale dense deployments more efficiently. Through the solutions referral partnership with CoreSite, customers can engage earlier, evaluate cooling strategies faster, and reduce friction as projects move toward deployment.
The announcement follows OptiCool’s recent partnership expansions across the data center and channel ecosystem, reflecting broader demand for two-phase cooling approaches as density requirements rise.
“CoreSite continues to advance its data center solutions, based on customer feedback, to meet increasing high-density computing requirements,” said Alec Gramont, VP of Product Strategy and Edge at CoreSite. “By collaborating with partners like OptiCool, CoreSite’s facilities can meet customers’ current requirements and anticipate future cooling needs.”
Partnership Highlights:
- Solutions Partner alignment to support customers deploying high-density infrastructure in CoreSite facilities
- Streamlined introductions and coordination when advanced cooling is required
- Earlier engagement and faster evaluation for next-generation infrastructure planning
