The High Density Directional Airflow Solution for Data Centers
The High Density Directional Airflow Solution for Data Centers

Total Air Capture (TAC) rate refers to the amount of air delivered through the airflow panel that is then captured by the server rack. The server rack profile below represents a standard 24" x 76" server rack. Lines have been added to show the three zones of the server rack. Zone 1 represents the bottom of the rack closest to the floor and Zone 3 represents the top of the rack farthest from the air supply. You will notice that the DirectAire grate delivers 93% of it's 2,600 CFM at .1" H2O to the face of the server.The data reported on the smoke test images below show the distribution of airflow through both panels for each zone in a 42U rack. You will notice the airflow through the DirectAire grate is spread evenly across the three zones of the rack. When racks are placed 6" from the edge of a DirectAire X2 panel as shown the airflow is divided evenly between the two adjacent racks.

Eliminate the Burden of Airflow Containment
Containment systems in a data center come with many challenges including fire code requirements, service distribution restraints and limited flexibility. Unlike other panels which throw air straight up in a vertical plume the DirectAire’s angular throw evenly distributes the majority of the air it delivers directly to the face of the rack providing effective containment when used in conjunction with best practices.
 |  |  |
| DirectAire’s 93%TAC rate enables you to gain near peak airflow without containment. | DirectAire X2 enables you to maximize airflow in aisles with a single row of airflow panels without containment. | Typical airflow panels require containment systems to ensure maximum airflow to the racks. |
High Density Cooling Capacity
DirectAire’s ability to deliver high volumes of air directly and evenly across the face of the server rack gives it the unique ability to handle very high density equipment. The table below lists cooling capacities per rack based on a mathematical calculation for systems without containment.
(CFM x Total Air Capture %) / 120 (CFM need to cool 1kW @ 25°F ∆) = kW per rack.

*Cooling capacities were calculated using the following formula:
(CFM x Total Air Capture %) / 126(CFM needed to cool 1kW @ 25ºF ) = kW per rack.
(CFM x Total Air Capture %) / 126(CFM needed to cool 1kW @ 25ºF ) = kW per rack.
Strong & Durable
Both DirectAire’s feature all steel construction making them the strongest airflow panels on the market. With a 2000 lb Rolling Load, 2500 lb Design Load and a Minimum Safety Factor of 2.0 equipment can be moved over the airflow panels without worry.

Improve Data Center Financial Performance
DirectAire maximizes the financial performance of any new or existing data center. The precise delivery of air reduces bypass airflow allowing new facilities to reduce the number of CRAH units. Retrofits can set CRAH units with fixed speed fans to standby mode or adjust variable fan drives to operate at a lower static pressure, saving energy. Likewise the 93% TAC rate eliminates the need for a full containment system. The facilities overall cooling capacity will also be improved allowing for the addition of IT equipment without the capital investments on infrastructure.
