Drives improved reliability in controlled supply air
Containment
Drives improved reliability in controlled supply air temperatures to the Rack
Critical Means to driver for higher return air temperatures to the cooling unit
Hi h t i t t i it iti tHigher return air temperatures increase unit capacities to lower unit count
EconomizationReduced mechanical refrigeration energy
