Outdoor or scavenger air Ir---- can be conditioned in the evaporative cooler such that the conditioned scavenger air can provide cooling to a cooling fluid circulat - I-1 © ing through the recovery coil. The reduced-temperature cooling fluid can provide liquid cooling or air cooling for an enclosed space N (for example, a data center) or for one or more devices that are enclosed or open to the atmosphere. Given the design and arrange - 0 ment of the pre- cooler, evaporative cooler and recovery coil in the plenum, the system can operate in multiple modes. The pre-cool - ,-t er can be configured to circulate a cooling fluid to condition the scavenger air. The pre-cooler fluid circuit can be coupled or de - .,- coupled from a process cooling fluid circuit.
