The DC 55 Air Grate available in dimensions 600mm x 600mm cast aluminum floor grate with a minimum open area of 55% is capable of delivering almost twice the CFM of the average perforated floor tiles. It only implies that the unit is capable of producing sufficient air to cool your high density equipment. The DC55 grate is the answer to your hotspot woes since it allows sufficient air to flow high enough to cool those servers placed close to the top of your server cabinets.
Backed by high durability, light grey powder coat finish to prevent corrosion, this heavy-duty perforated panel is actually capable of enduring a point load of over 4.5KN (1,000lb per square inch) and a uniform distributed load of over 13.5KN (PSB test results available upon request). It comes with a louvered damper enabling you to adjust the volume of air required for your particular application and equipment load. The louvered damper is adjustable from the top, which means you do not have to remove the tile to pave the way for those critical adjustments. The underfloor laminar air-flow is not affected is hardly impacted by the small profile of the DC 55 damper.
