DirectPerf 18942 25% Steel 24" Directional Airflow Floor Panel - Anti-Static - for Tate Bolted stringer systems

Tate's 18942 DirectPerf Panel uses patent pending technology to angle air towards equipment, achieving an impressive 93% Capture Index. This means 93% of the airflow delivered through the airflow panel is entering the face of the server rack, providing more capacity and energy efficiency than any other perforated airflow panel on the market with a 25% open area. Standard perf panels only achieve 30%-50% Capture Index, allowing the Directional Perf to double a traditional perf's cooling capacity using the same amount of air.

  • 25% 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

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.

The elimination of bypass air saves operating expenses in existing facilities and reduces capital expenditures on cooling equipment in new facilities. DirectAire's superior load performance is ideal for retrofit and new construction, easily integrating into your existing raised floor system.

Increase Energy Efficiency and Maximize Cooling Capacity

The DirectPerf has been designed to meet the cooling requirements typically associated with high air volume grate panels while still supplying the same air volume as a standard perforated panel. With the ability to cool twice the capacity of a standard panel, directional perfs can improve a facilities overall cooling capacity allowing for the addition of IT equipment without the capital investments on infrastructure.

Eliminate Waste and Improve Data Center Financial Performance

With a 93% Capture Index, wasteful by-pass airflow is virtually eliminated. 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.
