DirectAire® AL

Double the cooling capacity of a typical grate

The DirectAire® AL is an all aluminum lightweight directional airflow panel that uses patent pending technology to angle the air toward the equipment achieving a 93% Capture Index. This means that 93% of the airflow delivered through the airflow panel is entering the face of the server rack, providing the highest cooling capacity and energy efficiency of any aluminum airflow panel on the market.

Key Performance Characteristics

  • Lightweight cast aluminium grate design
  • 60% Open Area delivers 1,184 L/s at 25 Pa
  • Cools over 15kW per rack at 25 Pa
  • 6.7kN design load performance
  • Directional Airflow for 93% Capture Index
  • surface adjustable and automatic damper options

DirectAire® AL

Directional airflow panels maximize 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% Capture Index 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 capital investments on infrastructure.
