US data center firm Sabey has announced a new liquid cooling-focused partnership.

Sabey Data Centers this week announced a strategic partnership with OptiCool Technologies, the sole industry supplier of two-phase refrigerant pumped cooling systems for data center environments.

The companies said the collaboration will “simplify and accelerate the deployment of advanced cooling solutions” required to support high-density and AI workloads.

OptiCool’s two-phase refrigerant pumped systems support high-density data center environments. The company says that by using a non-conductive refrigerant that absorbs heat through phase change, OptiCool’s technology can work without chilled water, large mechanical systems, or significant data hall retrofits.

“Demand for high-density compute continues to accelerate, and cooling has become one of the most critical challenges our customers face,” said John Sasser, Sabey Data Centers CTO. “Partnering with OptiCool allows us to offer a differentiated cooling pathway that is both efficient and flexible. Together, we’re making it easier for customers to deploy advanced liquid cooling solutions while maintaining the operational clarity and reliability they expect from Sabey.”

A joint venture between Sabey Corporation and National Real Estate Advisors, Sabey Data Centers operates data centers across the US, with sites in operation or development in Quincy, Seattle, and East Wenatchee, Washington; New York City; Austin, Texas; Umatilla, Oregon; and Ashburn, Virginia. The company was recently set to buy 600 acres of land in Butte, Montana, for a potential data center development, and is expanding into Indianapolis, Indiana.

“Data center operators are under increasing pressure to support higher densities while managing energy use and sustainability goals,” said Lawrence "LL" Lee, chief channel officer at OptiCool. “By working with Sabey, we’re able to bring our two-phase refrigerant cooling systems into facilities designed specifically to support the next generation of compute. This partnership helps customers move forward with confidence as they transition to more advanced cooling architectures.”

The OptiCool Delta4T system uses R-513A refrigerant, with its systems operating near the vaporization point of the refrigerant, where its heat capacity is by far the greatest. The New York-based company offers rear door heat exchangers, refrigerant pumps, aisle containment systems, and cooling distribution units. It can offer up to 120kW of cooling capacity per rack.
