    Thanks guys... System is a pure constant flow (CRAH fan and chiller loop GPM of approx 320). As such, the only component of efficiency I can see is the compressor staging on the chiller. At current, with a 7 to 8 degree loop delta, the 1st set of compressors stay on constantly while the...

Trying to explain the importance of not have supply/return air mixing within the DC so that CRAH units take in only return air (High Delta T vs LOW). I understand that this will maximize the individual CRAH unit...
