Cooling Solutions for High-Density Computing
AI computing is increasing rack density, cooling demand and project delivery pressure. Beijing Hengrui supplies genuine ebm-papst EC centrifugal and axial fans for new AI cooling systems, capacity upgrades, equipment manufacturing and urgent replacement requirements.
Popular RadiPac and AxiBlade models are available from stock, supported by engineering selection, model cross-reference and fast international delivery.

AI training and inference infrastructure creates concentrated, variable and continuously changing heat loads. Cooling equipment must deliver the required airflow and pressure while maintaining efficiency, controllability and operational reliability across a wide operating range.
Fan selection is therefore no longer based only on maximum airflow. Engineers must also consider part-load performance, system resistance, redundancy, control capability, acoustic behaviour, equipment footprint and delivery schedules.

GPU clusters can place significantly more thermal load within a smaller physical footprint. Cooling systems must move air or reject heat efficiently without unnecessarily increasing space and energy consumption.

AI workloads do not always remain constant. EC fan speed control allows airflow to respond to changing system demand instead of operating continuously at full speed.

Cooling availability is critical to data center operation. Modular fan arrangements can support redundancy, staged control and maintenance strategies without relying on one oversized fan.

Rapid AI infrastructure deployment often creates shorter procurement windows. Ready-stock components and fast technical confirmation can help prevent cooling equipment from becoming a project bottleneck.
AI Workload → Heat Load → Cooling Equipment → EC Fan Control → Heat Rejection





Our fan solutions can be integrated into new equipment, system expansions, replacement projects and energy-saving upgrades across air-cooled and hybrid AI data center infrastructure.

Cooling support for high-density training and inference environments requiring stable airflow, pressure and variable-speed control.

EC fan solutions for large facilities where energy efficiency, modularity, redundancy and scalable cooling capacity are critical.

Cooling components for private AI environments, enterprise data centers and on-premise high-performance computing deployments.

Fan support for equipment that works alongside liquid cooling, including heat rejection, coolant distribution and auxiliary air-management systems.

Fan selection and supply support for manufacturers of CRAH units, fan walls, dry coolers, chillers, cooling towers and precision cooling equipment.

Replacement and EC upgrade support for existing data centers that need additional capacity, lower energy consumption or improved fan availability.
Send us your required airflow, pressure, voltage, installation dimensions or existing fan model.
The following product families cover different airflow, pressure, installation and heat-rejection requirements. They are presented with equal importance because the correct recommendation depends on the equipment design and required operating point—not simply on the product generation or series name.
Beijing Hengrui can help evaluate airflow, static pressure, installation dimensions, voltage, communication requirements and replacement compatibility before quotation.



Product guide
Compare key fan‑platform specs to find your ideal solution fast
| Requirement | RadiPac M | RadiPac C | AxiBlade EC Axial |
|---|---|---|---|
| Fan principle | Centrifugal | Centrifugal | Axial |
| Typical installation | Air-handling and pressurized airflow systems | Compact air-handling and modular fan systems | Heat exchangers and outdoor heat rejection |
| Impeller concept | Metal | Composite material | Axial blade platform |
| Airflow direction | Radial discharge | Radial discharge | Axial |
| Typical project need | High airflow, metal construction or larger sizes | Compactness, efficiency and broad HVAC integration | High-volume airflow through heat exchangers |
This comparison is a general guide. Model selection must be based on the actual operating point and equipment configuration.
For urgent AI data center projects, replacement work and equipment production, Beijing Hengrui maintains inventory of selected ebm-papst EC fan models. Availability changes regularly, so current quantity, price and lead time should be confirmed before order placement.

When cooling equipment production, site commissioning or replacement work is delayed by fan availability, our team can help check stock, review alternatives and confirm technically suitable options.



You may send the existing fan nameplate, part number, airflow requirement, pressure requirement or equipment drawing.
AI cooling projects often require more than a product catalogue. Customers need accurate model confirmation, reliable product sources, practical engineering communication and realistic delivery schedules.

Beijing Hengrui supplies genuine ebm-papst products through an authorized agency relationship, helping customers maintain product traceability and procurement confidence.

Selected centrifugal and axial EC fan models are maintained for urgent projects, replacement requirements and equipment-manufacturing demand.

Our team can support fan selection based on airflow, pressure, voltage, dimensions, control requirements, installation conditions and existing fan references.

We support professional export packing, documentation and international delivery coordination for contractors, equipment manufacturers and data center customers.
