computer room air handler (CRAH)
A computer room air handler (CRAH) is a device used frequently in data centers to deal with the
heat produced by equipment. Unlike a computer room air conditioning (CRAC)
unit that uses mechanical refrigeration to cool the air introduced to a data center, a CRAH uses
fans, cooling coils and a water-chiller
system to remove heat.
