DirectPerf 18956 32% Steel 24" Directional Airflow Floor Panel - Anti-Static - for Tate Bolted stringer systems

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.

  • 32% open area
  • 24 Inches square all steel construction
  • Concentrated load rating up to 1250 lbs
  • Protected from corrosion by anti-static powder coat finish- 25,000 to 20,000,000,000 ohms when tested at 500 volts per NFPA 99
  • Patented Intermingled airflow vanes for directional airflow
  • Class A flame spread rating
  • Non-combustible material
  • Pre-drilled for field mounted opposed blade dampers.
  • Directional Airflow for 88% Capture Index
  • SparkLite White anti-static powder coat

1. System Design Load is based on permanent set ? 0.010" and is verified by loading panels in accordance with the CISCA concentrated load method but with panels installed on actual understructure instead of steel blocks. (Testing on blocks does not represent performance of an actual installation.) Ultimate, Rolling, and Impact Load tests are performed using CISCA Test Procedures.
2. Safety Factor is Ultimate Load divided by Design Load.

Tate's DirectPerf maximizes energy efficiency and the overall capacity of any new or existing data center 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.
