Update:
Though we had determined that the drain line on the steam distribution manifold was not clogged we decided to cut the copper line to see for our self. We found a green slime that was restricting the flow of water. We are not sure where this slime came from; we do have very hard water...
Compositepro, I see what you are saying about blower immediately flinging water to the wall; I was thinking about maybe splitting the steam line adding another manifold in the other blower but, that would probably just create two different water puddles. As far as the steam injection stopping...
CountOlaf, The Data Aire Technical Support has not returned my calls or replied to my emails in over a week, I think they don't want to admit the pore design. Problem is, at this 24/7 critical facility I don't have time to just wait around so i am trying to find ideas elsewhere.

Tys90, This is the standard location of the manifold on all five of our Data Aire CRAC units. The other Data Aire units also have this issue but not as bad, once the humidifier shuts off the small bit of water that has collected is dried up within a minuet. All settings on the five units are...
Compositepro, The drain is on the bottom of the manifold. I will speak to our Mechanical contractors about insulating the manifold and see what they think.
I'm not sure what you meant by "That's a good condenser design if you wanted to heat the air rather than humidify it.", could you elaborate.
Tys90, We have four other Data Aire units (same model) that are not having this issue. I agree we may need to move the steam distribution manifold but are looking into other options before changing any factory specks. Also, we can not move it downstream, we do not have any duct work connected...
ChasBean1, the Capacity pot is turned all the way down to 25% (the lowest setting). We checked the resistance of the potentiometer set at 25% compared to our other Data Aire Units potentiometers set at 25%; They were only off by 1/10th of a K Ohm. We also verified that the drain line is free of...
tys90,
Yes that is my guess.
ChrisConley, tys90,
I have attached pics that show the blower fan and steam distribution manifold. The first pic shows the manifold size, about 8in (the blower fan is 14in); and where water is building up on the inside of the fan...
willard3,
We did call out our Mechanical contractor and he is stumped. Other than redesigning the factory built steam distribution system they do not know what to do. Our Mechanical contractors have a lot of experience with CRAC units and Data Center cooling but are new to Data Air CRAC units...
sridhar1312,
The air speed in the CRAC (Computer Room Air Conditioner) is ok. There are two blower fans and water is only coming out of the one that the humidifier's steam dispenser is connected to and only leaks when the humidifier is on.

We are getting excessive water build up under one of our DATA AIRE CRAC Units (model# DAAD-2034)during humidification (the humidifier in the CRAC Unit is a Nortec MES-U series). We have changed out the cylinder which helped a little; have also checked the drain line, which is clear; and the...
Thank you Ross, I have sent an e-mail. I hope they have some answers. I have found that Airflow is now a part of APC but the APC website does not have any info on the older Airflow units.

I am trying to find a manual, or just any info, for our 5 original CRAC units. They are all Airflow units, model# CCT-23CV4, manuf. date 3/15/96. I can not find anywhere online. Any information is appreciated.
