2.X CDU
Overview
High-Flow Liquid Cooling for Evolving AI Platforms
LiquidStack CDU 2.X delivers up to 2.5 MW of cooling at 4°C ATD, with 3,750 lpm at 3.5 bar of available head pressure. This gives operators the hydraulic headroom to meet demanding rack flow and differential pressure requirements as AI workloads evolve.
-
More Than Megawatts. More Hydraulic Headroom.
As AI rack densities increase, flow-per-kW and rack pressure drop requirements are rising. Headline megawatt capacity alone does not show whether a CDU can deliver the required flow at usable pressure.
With up to 2.5 MW of cooling at 4°C ATD, CDU 2.X occupies the capacity sweet spot between conventional rack-scale CDUs and centralized liquid cooling platforms.
-
One CDU Architecture. Multiple Generations of AI.
CDU 2.X is designed around changing flow-per-kW and rack differential-pressure requirements, helping support current and successive AI compute platforms without redesigning cooling around one silicon specification.
-
Configured to Fit Facility Requirements
Configurable power, controls, redundancy, piping and monitoring help align CDU 2.X to site-specific infrastructure, operating models and performance objectives instead of forcing the facility to adapt to the CDU.
-
Flexible and Resilient Deployment
CDU 2.X supports end-of-row and rack-adjacent layouts, with configurable redundancy strategies and concurrently maintainable components that help sustain resilience in high-density AI environments.
-
Efficient Integration with Your Facility.
Low-approach thermal performance, warm-water operation up to 45°C and optional ultra-low-harmonic VFDs help CDU 2.X integrate efficiently with facility cooling and electrical infrastructure.
