Adding humification to small server room

Adding humification to small server room

Adding humification to small server room

(OP)
Hi,
We had a project to provide new AC to small (2 tons worth of AC) server room. Person 1 on job selected small Liebert which would have had humidification, but turns out unit would have been hard to fit in room. Job switched to person 2 who selected unit which fits (Mitsubishi ceiling suspended unit) but no humidification. Some miscommunication here, I know..Room is just fine now with respect to temp but is lacking humidity-should be 40% to 60% and is at 20% RH.. Can we add to room small (VERY small) humidifier w/humidistat? I know usually with computer room ac units these are integral. But here we have such small load and space problems, plus we already have AC unit there....Any thoughts plaese?

RE: Adding humification to small server room

I've ran into a similar situation. I added a Steam Humidifier to the room - definitely not ideal, but will work in a pinch.

RE: Adding humification to small server room

Is the issue personal comfort? My understanding is that most server room (nearly all) have no minimum humidity requirement.

I'd get confirmation from someone that they need higher humidity for some reason.

RE: Adding humification to small server room

Most server manufacturers suggest a minimum RH%...

Problems can arise with low humidity: Copper wires can corrode, dust may collect easier, higher static electricity, etc... If it's too high, condensate may become an issue.

Thanks very much! We are putting in a humidifier, client seems Ok with it,although the neater solution would be of course a proper AC room unit ..
The server equipment does  need 40-60% RH, apparently.

Thnks,EE, those look good!

RE: Adding humification to small server room

You are very welcome.

RE: Adding humification to small server room

You can get standalone humidifiers from Armstrong as well.

ASHRAE now specifies the acceptable humidity range as a dewpoint, and I can't remember the numbers off hand, but it is more relaxed from the old 40-55% RH range.

I didn't know about Armstrong. Thank you.
