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. Airflow Performance Information Pressure (in.

*Cooling capacities were calculated using the following formula:(CFM x Capture Index %) / 126(CFM needed to cool 1kW @ 25ºF ?T)= kW per rack. UNDERSTRUCTURE OPTIONS - 24" Bolted Stringer
