Data Center Cold Aisle Service Solution

Cold Aisle Containment (CAC) systems optimize data center cooling by isolating cold supply air from hot exhaust, improving energy efficiency, airflow management, and equipment performance.

What is Cold Aisle Containment?

Cold Aisle Containment (CAC) is a data center cooling strategy that isolates the cold air supplied by CRAC/CRAH units from the hot exhaust air generated by servers. By enclosing the cold aisle with doors, ceiling panels, and structural frames, CAC ensures that cold air flows directly to server intakes, preventing mixing with hot air and eliminating hot spots that can compromise equipment performance and energy efficiency ( ).

Benefits of Cold Aisle Containment

• Energy Efficiency: CAC reduces the workload on cooling units, allowing higher supply air temperatures and lowering energy consumption. For example, Virtustream's facility in San Francisco achieved a 10°F (5.5°C) increase in supply temperature, saving over 544,000 kWh annually ( ).
• Improved Airflow Management: By creating a uniform and predictable airflow, CAC eliminates hot spots and ensures servers operate within manufacturer-recommended temperature ranges ( ).
• Scalability and Flexibility: Modern CAC systems are modular and can be floor-standing or ceiling-suspended, accommodating different rack heights, obstacles, and future expansion ( ).
• Operational Reliability: High-quality sliding doors, clear panels, and synchronized mechanisms allow easy access while maintaining containment integrity ( ).

Installation and Design Considerations

• Turn-Key Solutions: Providers like EDP Europe and Altimir offer custom-engineered, turnkey CAC systems that include design, fabrication, installation, and post-installation support ( ).
• Modular and Scalable: Systems can be expanded or reconfigured as data center needs grow, supporting hyper-scale environments ( ).
• Integration with Existing Infrastructure: CAC systems are compatible with standard rack sizes (42U, 45U, 48U) and can integrate with cabling, power, and HVAC systems without major retrofits ( ).
• Energy Savings and Compliance: CAC helps data centers meet ASHRAE TC 9.9 guidelines for temperature management and can reduce cooling costs by up to 30% ( ).
