What is the Open Compute Project OCP Project Deschutes ?

Leading the liquid cooling revolution

At the 2025 Open Compute Project (OCP) Global Summit in San Jose, California, Eaton showcased the ROL4000 CDU, which meets Google’s latest two-megawatt Project Deschutes coolant distribution unit (CDU) requirements. The fifth-generation Deschutes platform represents a major advancement in open, scalable liquid cooling for enterprise, cloud and hyperscale data centers. Eaton’s design and manufacturing excellence highlights its leadership in developing high-performance, energy-efficient cooling systems that enable next-generation compute infrastructure.

Clean power and robust protection

The Project Deschutes CDU specification requires 2 megawatts of cooling capacity with an aggressive 3°C approach temperature difference (ATD) to meet the growing thermal demands of modern AI and cloud workloads. It supports advanced cold plate designs that maximize heat transfer efficiency for high-power processors and operates at an available pressure of 80 PSI.

To maintain coolant integrity and extend system life, Project Deschutes CDU utilizes 0.2-micron side stream filtration and fully redundant power feeds for each pump circuit. A dedicated 230 VAC convenience port simplifies setup and maintenance in existing data center environments, while IEEE 519 ultra low harmonic distortion (ULHD) Variable Frequency Drives ensure clean, stable facility power.

Compact, modular design for easy retrofit

Eaton developed the ROL4000 to support high-capacity liquid cooling within existing data center infrastructure, as intended by Project Deschutes. Its modular architecture simplifies integration with current infrastructure while enabling scalable, open cooling deployments. The platform advances the Open Compute Project’s mission to deliver interoperable solutions that enhance thermal performance, improve energy efficiency and support sustainable data center growth worldwide.

Engineer the future with Eaton’s expertise

Eaton’s global high-capacity facilities manufacture cold plates, liquid cooling loops and the two-megawatt Project Deschutes CDU. With engineering and service teams across North America, Europe and Asia Pacific, Eaton delivers scalable supply chain strength, responsive regional support and consistent manufacturing quality.

Eaton’s participation in the 2025 Open Compute Project Global Summit reinforces its commitment to advancing open, sustainable and high-performance liquid cooling technologies. Backed by decades of thermal management expertise and a proven legacy in liquid cooling design, Eaton drives the development of efficient, reliable and globally deployable data center infrastructure. Collaborate with Eaton to engineer the next-generation cooling solutions that powers the future of data-driven innovation.
