Data Center Cooling Solutions – Axial Fans & EC Centrifugal Fans for AI and Cloud Infrastructure

The explosive growth of AI workloads and cloud computing has pushed data centers worldwide to reimagine their cooling strategies. Efficient cooling is now mission-critical: up to 40% of total energy consumption in a data center can be tied to cooling systems.

AFL’s energy-efficient fan solutions provide a one-stop approach to axial fans, EC centrifugal fans, and intelligent EC motor options tailored for the stringent cooling requirements of modern data centers.

Why Efficient Cooling Is Critical for Data Centers

• AI and cloud workloads create unprecedented heat densities, making airflow performance crucial.

• Regulatory pressures demand lower energy consumption and emissions.

• Downtime costs from overheating can exceed millions in lost revenue and SLA penalties.

Fan Technologies for Data Center Cooling

Axial Fans for Data Centers

Axial fans deliver high airflow at relatively low static pressures, ideal for rack-level or room-level ventilation.

• Typical airflow range: 2,000–30,000 m³/h depending on size.

• Noise comparison: AC axial fans are typically 5–7 dB(A) louder than EC axial fans at equivalent airflow.

• Hot-swappable options: Available for maintenance in mission-critical racks.

EC Centrifugal Fans for Data Centers

EC centrifugal fans excel in applications requiring high static pressure and precise speed control.

• Typical static pressure range: 300–1,200 Pa.

• PUE improvement: Switching from AC centrifugal fans can yield 8–12% better PUE.

• RS485 communication: Supported for integration with building management systems.

Energy-Efficient Fan Solutions with Intelligent EC Motors

Upgrading to integrated EC motor-driven systems reduces throttling losses, enables dynamic speed control, and simplifies installation:

• Energy savings: Up to 30% compared to legacy throttling methods (dampers, baffles).

• IoT-ready: Intelligent EC motors support RS485, Modbus, and BACnet protocols.

• Reliability: MTBF ratings exceed 60,000 hours with advanced bearing and fault detection options.

Global Market Demand

• North America & Asia-Pacific: Highest growth in data center cooling demand driven by hyperscale cloud providers and AI data hubs.

• High-altitude & high-humidity environments: AFL fans offer derating and corrosion-resistant options for challenging site conditions.

Application Scenarios

• 42U server racks: Axial fans with low noise (<65 dB(A)) and hot-swappable design.

• Cold-aisle containment: EC centrifugal fans with compact footprints for modular data centers.

• Liquid-cooled data centers: Axial fans support hybrid cooling strategies even when direct liquid cooling is implemented.
