Just to follow up, because of the lack of "thermal ballast" raid mentions, it is a good idea to seek out DX in-row cooling units that can be dual-wired: fans and controls connected to UPS and compressors, humidifiers and reheats wired to generator only. This way, UPS capacities need not be sized for huge loads. If your vendor doesn't support this, ask them to!
