Solution Pathway

Integrate air and liquid cooling without confusing the rack plan.

PAI supports mixed cooling environments where existing air-cooled systems, liquid-cooled racks, CDUs, manifolds, QDCs, and deployment hardware must work together during phased high-density upgrades.

Mixed Cooling Environment

AIR

Existing air-cooled infrastructure

Current racks, density limits, airflow constraints, and deployment conditions.

LC

Liquid-cooled rack layer

Cold plates, manifolds, QDCs, CDU interfaces, and rack-level cooling hardware.

HYB

Hybrid integration plan

A coordinated bridge between existing infrastructure and higher-density GPU, HPC, colocation, and other high heat-load deployments.

What this supports

A cleaner path for phased cooling upgrades.

Hybrid cooling projects are not just product purchases. They require planning across old and new rack environments so components match the deployment path.

Mixed environments: Supports facilities operating both air-cooled and liquid-cooled rack systems.
Phased upgrades: Helps transition selected racks or clusters without treating the whole site as one single conversion.
Component alignment: Coordinates cold plates, manifolds, QDCs, CDU interfaces, and rack hardware.
Deployment sequencing: Supports planning around lead times, compatibility, rack layout, and rollout timing.
Density growth: Useful when GPU, HPC, colocation, or other high heat-load density increases faster than the existing cooling environment can support.
Project-specific sourcing: Component selection can be aligned to the actual cooling mix and infrastructure plan.

Workflow

How PAI approaches hybrid cooling integration.

1

Review the current environment

Identify which systems remain air-cooled, which racks are moving to liquid cooling, and where the main deployment constraints are.

2

Define the liquid-cooled layer

Align cold plates, rack manifolds, CDU connections, QDCs, and required rack-level hardware around the target architecture.

3

Coordinate sourcing and deployment

Match components to project requirements, supplier lead times, installation sequence, and compatibility across the mixed environment.
