Denco Units in Computer Room.

Hi Guys,

Any ideas much appreciated, we have a computer room at 103sqM, cooled by three Denco D74 units, in turn fed by two York air cooled Liquid Chillers, we number them 1 to 3, now the problem is that number 1 seems to be providing the full load for the room!! i can work on 2 or 3 with only a few degrees lost, if i turn off #1 the temp goes through the roof, the room has 36 servers in it, i have conflicting information, on site O&M manuals state each unit gives 91.36kW Duty, Denco say 61.3kW Duty?? im going with Denco, they recon two units can comfortably control room at 21Deg, so, what am i missing with #1.

Hope my written words and brain have kept up with each other, any questions please ask.

Thanks.
