Cooling Challenges in High-Density Data Centers

AI workloads, rising rack power density and 24/7 operation place increasing pressure on cooling systems, making airflow efficiency, redundancy and precise control more important than ever.

Outdoor Exposure & Environmental Protection

Cooling Challenge: Outdoor cooling equipment may be exposed to changing temperatures, rain, dust and other environmental conditions.

Recommended Solution: Fan solutions designed for outdoor cooling applications provide reliable airflow and support stable operation under changing environmental conditions.

High Cooling Energy Consumption

Cooling Challenge: Cooling fans operate for thousands of hours each year, making fan efficiency a major contributor to total data center energy use.

Recommended Solution: EC fan technology combines efficient motors, optimized aerodynamics and variable-speed control to reduce energy use, particularly under partial-load conditions.

Continuous 24/7 Operation

Cooling Challenge: Cooling failure can lead to rising server temperatures, reduced computing performance or unplanned downtime.

Recommended Solution: Reliable fan systems, redundancy and monitoring functions help maintain airflow even during component faults or maintenance events.

Limited Space & High System Resistance

Cooling Challenge: Dense coils, heat exchangers, filters and compact cooling modules create high airflow resistance.

Recommended Solution: High-pressure fan designs maintain stable airflow across coils and cooling components while minimizing installation footprint.

Cooling Solutions Across the Data Center

ebm-papst fan technology supports airflow and heat rejection from server-level cooling to room cooling and outdoor heat rejection systems.

CRAC & CRAH Units

CRAC and CRAH units continuously circulate conditioned air through data halls. Efficient centrifugal EC fans help deliver stable airflow while reducing power consumption and maintenance requirements.

Key Benefits:

High Airflow Efficiency: Efficient air circulation for data halls.Variable Speed Control: Match airflow to real-time cooling demand.Redundant Fan Arrays: Improve system availability and serviceability.

InRow Cooling & Rear Door Heat Exchangers

High-density racks require cooling close to the heat source. Compact high-pressure fans help move air efficiently through dense coils and restricted spaces.

Key Benefits:

High Static Pressure: Maintain airflow through dense coils.Compact Design: Ideal for space-constrained cooling modules.Precise Control: Adapt airflow to changing rack loads.

Liquid Cooling & CDU Heat Rejection

Liquid cooling removes heat directly from high-power processors, while secondary air-side systems still require efficient fans to reject heat through liquid-to-air cooling units and heat exchangers.

Key Benefits:

High Heat Rejection: Support growing AI cooling loads.Flexible Integration: Suitable for liquid-to-air cooling systems.Energy Efficiency: Reduce auxiliary cooling power.

Chillers, Condensers, Dry Coolers & Cooling Towers

Outdoor heat rejection systems require large-volume airflow, high efficiency and reliable operation across changing ambient and load conditions.

Key Benefits:

Large Airflow Capacity: Designed for large heat exchanger surfaces and cooling tower applications.Energy-Efficient Operation: EC speed control helps match airflow to actual cooling demand.Outdoor Reliability: Suitable for continuous operation in demanding outdoor environments.

AHU & Fan Wall Systems

Air handling units and fan wall systems require efficient, controllable airflow for ventilation, filtration, cooling and air distribution across commercial and industrial facilities.

Key Benefits:

Flexible Airflow Control: Variable-speed EC fans adapt airflow to changing system demand.Modular Fan Wall Design: Multiple fans can be arranged in parallel for flexible capacity and system configuration.Direct-Drive Efficiency: EC plug fans eliminate belts and pulleys, simplifying installation and reducing mechanical components.
