DirectPerf 32%

Same cooling capacity as a typical grate

DirectPerf 32% angles the airflow toward the server rack to significantly improve energy efficiency and reduce bypass air. DirectPerf 32% provides nearly the same cooling capacity as a standard 56% open area grate using about half the airflow. The panel is designed with a unique combination of directional and vertical perforations which provides evenly distributed air flow across the entire face of a typical IT rack.

Key Performance Characteristics

  • 32% open area delivers 529 L/s at 25 Pa when installed without a damper.
  • Directional air flow achieves a 88% Capture Index.
  • Cools up to 8kW per rack at 25 Pa
  • Can save over 40% in annual fan energy savings.
  • Easily integrates into an existing 60cm raised floor systems

DirectPerf 32%

Tate's DirectPerf maximises energy efficiency and the overall capacity of any new or existing data centre by nearly eliminating bypass air. The precise delivery of air to the face of the rack reduces by-pass air allowing new facilities to in-turn 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 88% Capture Index eliminates the need for an aisle containment roof. The facilities overall cooling capacity will also be improved allowing for the addition of IT equipment without the capital investments on infrastructure.
