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.
Airflow Performance Information
|Pressure (in. H2O)||CFM w/ No Damper||kW/Rack|
*Cooling capacities were calculated using the following formula:(CFM x Capture Index %) / 126(CFM needed to cool 1kW @ 25ºF ?T)= kW per rack.
