Vertiv and Compass Datacenters have launched a hybrid cooling system designed to simplify the adoption of liquid cooling in data centers while supporting mixed workloads. The Vertiv™ CoolPhase Flex system combines refrigerant-based air cooling with liquid cooling capabilities, addressing the rising demand for high-density computing driven by AI applications. The solution will debut in Compass facilities in early 2025 as part of a multi-year, multi-billion-dollar supply agreement between the companies.
The CoolPhase Flex operates as a direct expansion (DX) air-cooling system with integrated economization, enabling energy-efficient cooling for current workloads. As data centers incorporate more high-density systems, liquid cooling capabilities can be activated quickly without the need for extensive retrofitting. The system is designed for external installation, conserving data center floor space and reducing deployment complexity. Its compatibility with modular data center environments further supports flexible scaling to meet evolving needs.
Compass has also adopted Vertiv’s Next Predict service platform, leveraging predictive analytics to enhance maintenance operations. This proactive approach reduces potential downtime by using historical and real-time data to identify maintenance needs before issues arise. Chris Crosby, Compass’ CEO, emphasized the value of the collaboration, stating, “Vertiv brought our vision to life with a level of flexibility that is unparalleled in the marketplace.”
Key Points:
• Product Overview: Vertiv CoolPhase Flex integrates air and liquid cooling in one system, adapting to current and future high-density computing demands.
• Energy Efficiency: Uses pumped refrigerant economization for air cooling and converts seamlessly to liquid cooling when needed.
• Deployment Benefits: Modular design minimizes retrofit requirements, reduces downtime, and allows external installation to save indoor space.
• Predictive Maintenance: Vertiv’s Next Predict service platform shifts maintenance operations from reactive to proactive with data-driven insights.
• Timeline: Initial deployment scheduled for Q1 2025 as part of a long-term supply agreement.
“Our customers want fast, practical, and energy-efficient ways to introduce liquid cooling for AI and other applications. Vertiv CoolPhase Flex provides the flexibility to meet changing requirements without significant disruption,” said Chris Crosby, CEO of Compass Datacenters.
