What’s Built In

Air today, liquid tomorrow — without swapping the unit.

Industry’s first packaged system offering both liquid and air cooling for high-density and AI workloads

Field-convertible between air and liquid cooling with minimal operational disruption

Matches current Liebert® DSE (DP400) capacities with only 5 ft of additional footprint

Deploys initially as air cooling (matching the legacy Vertiv™ Liebert® DSE packaged unit) or as liquid cooling

Redundant fans and DX circuits mitigate risk and ensure operational continuity

Supports mixed workloads where liquid-cooled and air-cooled servers are deployed in the same environment, optimizing for varying heat loads across the whitespace — developed in collaboration with Compass Datacenters.
