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.

*Cooling capacities were calculated using the following formula:(CFM x Capture Index %) / 126(CFM needed to cool 1kW @ 25F ?T)= kW per rack. NOTE: GrateAire Model 18979 does not have a damper.

Question: RE: Tate GrateAire 24" with Damper - what is best orientation to rack, slots perpendicular or parrallel?
Answer: Thank you for your inquiry, With the Damper, you would orient the slots perpendicular to the rack. The slots on the damper can be adjusted from 0-100% range towards the rack with quarter turn adjustment.
