Source the right CDU for your deployment.

A Coolant Distribution Unit (CDU) transfers heat between a facility-side cooling system and a technology cooling loop serving liquid-cooled IT equipment.

Depending on the architecture, a CDU may manage flow, pressure, temperature, filtration, redundancy, controls and monitoring for direct-to-chip cooling or other data center liquid-cooling applications.

CDU Sourcing is an independent B2B sourcing platform focused on Coolant Distribution Units and liquid-cooling infrastructure for AI, HPC and high-density data centers.

We help buyers structure project requirements, identify potential manufacturers and integrators, and organize supplier discovery.

No.

CDU Sourcing does not manufacture Coolant Distribution Units.

We operate as an independent sourcing and supplier-discovery platform.

Not by default.

Supplier matching is intended to be based on project requirements, technical fit, geography and commercial context rather than a preferred manufacturer.

Any specific commercial relationship should be disclosed where relevant.

A buyer submits project requirements through the RFQ form.

CDU Sourcing reviews the sourcing parameters and evaluates potential supplier fit.

Relevant manufacturers or integrators may then be considered for introduction.

The buyer and supplier can continue technical and commercial discussions directly.

Evaluate suppliers against the complete deployment context, including cooling duty, architecture, operating conditions, controls, geography, service capability, documentation, lead time and commercial scope.

A supplier that fits one AI data center or HPC project may not fit another project with different facility integration, fluid, footprint or support requirements.

Use a common requirement set and compare stated performance at the same operating conditions. Review FWS and TCS temperatures, flow, pressure, fluid compatibility, redundancy, controls, footprint, service coverage and lead time alongside nominal capacity.

In-rack CDUs are located within or closely associated with an individual rack. In-row CDUs serve equipment from the data center row. Facility CDUs are typically larger systems that support multiple racks, rows or a broader liquid-cooling deployment.

The appropriate format depends on capacity, distribution topology, footprint, facility connections, redundancy and service strategy.

Useful information may include:

• Cooling capacity
• CDU architecture
• Project location
• Target deployment date
• Quantity
• Cooling temperatures
• FWS and TCS supply/return conditions
• Flow requirements
• Pressure requirements
• Fluid type
• Redundancy
• Controls
• Physical constraints
• Required certifications
• Commercial scope

Incomplete or early-stage requirements are also acceptable.

No.

Early-stage, budgetary and active procurement requests can all be submitted.

The more relevant project information available, the easier it is to evaluate potential supplier fit.

No.

Submitting a sourcing request does not create a purchase obligation, supplier award or engineering approval.

No.

RFQ information is not intended to become a public marketplace listing.

Relevant project information may be shared selectively with potential suppliers as part of the sourcing process.

Do not submit trade secrets, passwords, security credentials or highly sensitive proprietary information through the initial RFQ form.

Where confidentiality is required, sensitive documentation can be exchanged later under appropriate arrangements between the relevant parties.

No.

CDU Sourcing supports sourcing and supplier discovery.

Final engineering validation, design approval, equipment selection, commissioning and operational acceptance remain the responsibility of the buyer, engineering team and selected supplier.

No.

CDU Sourcing does not guarantee manufacturer performance, equipment performance, delivery, warranty obligations or contractual outcomes.

Buyers should perform appropriate technical and commercial due diligence before placing an order.

Yes.

Manufacturers and integrators may submit their company and product information for consideration in future sourcing opportunities.

Joining the supplier network does not guarantee RFQ volume, introductions or commercial awards.

No.

The platform is designed for international sourcing.

Actual supplier availability and service coverage depend on the requirements and destination market of each project.

Potential applications include:

• Direct-to-chip liquid cooling
• Rear-door heat exchanger systems
• AI and GPU clusters
• HPC deployments
• In-rack CDUs
• In-row CDUs
• Facility-level CDUs
• New data center deployments
• Cooling retrofits
• Pilot projects
• Large-scale rollouts
