Edge Data Center Cold Aisle Low-Loss Vendors

Altimir and Upsite are leading vendors offering high-performance cold aisle containment solutions for edge data centers, designed to optimize airflow and minimize energy loss.

Key Vendors and Solutions

Altimir Data Center Solutions specializes in custom-engineered hot and cold aisle containment systems that improve airflow efficiency, reduce operational costs, and support high-density server deployments . Their solutions are scalable and adaptable, suitable for both raised floor and hard floor overhead applications. Altimir's cold aisle containment (CAC) systems create uniform airflow, ensuring predictable cooling performance while reducing energy consumption and carbon footprint . Upsite Technologies offers the AisleLok® modular containment system, which includes swing doors, drop-away ceilings, chimneys, and filler panels for cold aisle applications . These components are designed for quick installation with minimal disruption, using high-quality, flame-rated materials. The system allows for precise airflow management, closing gaps between racks, and optimizing cooling efficiency in partially populated aisles .

Features to Consider

• Airflow Optimization: Both vendors provide solutions that prevent hot and cold air mixing, maintaining low-loss airflow and consistent temperature across racks .
• Modularity and Scalability: Systems can be customized to fit specific aisle widths, heights, and data center layouts, making them suitable for edge deployments with space constraints .
• Integration with Cooling Systems: Cold aisle containment can complement in-row or rack-level air cooling and can be combined with liquid cooling solutions for high-density AI or edge workloads .
• Energy Efficiency: Proper containment reduces fan power requirements and improves cooling efficiency, lowering operational costs and environmental impact .

Edge Data Center Considerations

For edge deployments, where rack power densities are increasing (20–40 kW or higher), cold aisle containment alone may not suffice. Combining containment with liquid cooling technologies such as rear door heat exchangers, direct-to-chip cooling, or immersion cooling can handle extreme heat loads while maintaining low-loss airflow . Selecting a vendor should consider integration capabilities, ease of installation, and maintenance requirements in constrained edge environments. By evaluating vendors like Altimir and Upsite, edge data center operators can implement low-loss cold aisle containment that maximizes cooling efficiency, supports high-density racks, and reduces energy consumption.
