is always recommended to ensure top efficiency, but not
required. It is an excellent solution when attempting to cool widely varying heat loads, (ie. exceeding

quirements in real-time.
The 2T rack temperature sensors installed in the sensor boxes of the containment can be used to con-
trol the fan speed of the unit in the SmartAisle
TM
mode.
Version “Without Air Discharge Baffles” can be used in SmartAisle
TM
