A Megawatt of Cooling Capacity

Highest Capacity CRAH in the Data Center Industry

The CyberAir CFD-1080 is the largest perimeter CRAH in the data center industry, offering up to 96,000 CFM/987 CFM/ft²of air handling capability. The CFD-1080 comfortably maximizes the cooling capacity per square foot, while allowing for ease of rigging and modularity.

Ideal Applications

Hyperscale Data Centers
Colocation Data Centers
Cloud ISP
Enterprise Data Centers

Modular Deployment

The CyberAir 1080 data center CRAH is uniquely designed for modular deployment, with six separate sections (two fan, two coil, and two return filter plenum sections) delivered. Once fully assembled, the 1080 stands an impressive 13 feet tall. The modular CRAH unit design allows for ease of rigging, solving one of the major challenges for data center infrastructure equipment deployment.

Easier to handle & maneuver smaller sections
Added system redundancy
Split sections for access limitation
