Data Center Products

• Allows for directional airflow delivery to two racks when the existing cold can only accommodate one airflow panel.
• Capable of cooling over 12.5kW per rack due to evenly split nature of directional airflow paths.

Total Air Capture (TAC) rate refers to the amount of air delivered through the panel that is then captured by the server rack placed in front of that panel.

The black box 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.

Note that the DirectAire® X2 airflow panel delivers 93% of its 2,600 CFM at .1" H2O to the face of the server. You will notice the airflow through the DirectAire® X2 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.

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® X2's angular throw evenly distributes the majority of the air it delivers directly to the face of two racks providing effective containment when used in conjunction with best practices.

DirectAire® X2'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. Laboratory testing was conducted using load banks to measure the cooling effectiveness and verify the calculated kW/ rack heat loads.

*Cooling capacities were calculated using the following formula:(CFM x Total Air Capture %) / 126(CFM needed to cool 1kW @ 25ºF )= kW per rack.

*System load tests are conducted following CISCA's Recommended Test Procedures with the exception of Design Load. Design Load is a CISCA Concentrated Load Test performed on actual understructure using yield pint and safety factors in place of deflection.
