AI is driving a seismic shift in data center infrastructure, demanding faster, more flexible thermal management. As companies race to deploy AI workloads while still supporting traditional cloud applications, the pressure is on to rethink cooling strategies that can do both. All without slowing down innovation.
That’s why Compass Datacenters partnered with Vertiv to co-develop the Vertiv™ CoolPhase Flex: a first-of-its-kind hybrid cooling system that combines air and liquid cooling in a single unit. Designed to support today’s mixed workloads and tomorrow’s high-density compute.
One Unit. Two Cooling Modes.
Traditional cloud servers can be cooled with air, but AI workloads generate far more heat and require liquid cooling. Until now, data center operators had to choose one path or build out separate systems. Limiting flexibility and increasing costs.
The Vertiv CoolPhase Flex eliminates that trade off by integrating both air and liquid cooling into a single modular unit. This solution lets customers switch from air to liquid cooling without impacting operations by executing a standard MOP procedure.
Fast Deployment. Scalable Design.
Co-developed in early 2024 and deployed at our Phoenix, AZ campus just months later, the Vertiv CoolPhase Flex proves what’s possible when engineering innovation meets supply chain partnerships. The unit fits seamlessly into Compass’ modular data center design, accelerating deployment as it fits within an existing footprint.
Benefits include:
- Hybrid air + liquid cooling in a single system
- Quick installation using modular, prefabricated parts
- On-demand flexibility to meet AI and cloud workloads
- Reduced operational disruption and faster time to scale
Designed for the Demands of AI
In an era where every week counts, the Vertiv CoolPhase Flex helps you stay ahead of rapidly shifting workload requirements. Whether you’re scaling AI infrastructure or supporting a mix of legacy and high-performance systems, this solution removes uncertainty—and ensures your investment is future-ready.
The launch of the Vertiv CoolPhase Flex marks a major milestone for Compass and Vertiv and for the data center industry at large. It’s not just a cooling system. It’s a strategy for sustainable, scalable growth in the AI era.
