Steve, It certainly is possible. We have a dryer connected in-line with our compressor, and I'd bet my next paycheck if I go out and check the traps right now I'll find no water...and I haven't looked at them in more than a month. In our system the compressor tank itself does need regular draining due to the condensation build-up, but very little, if any, moisture gets in the lines. Sounds like your dryer isn't doing it's job or there's outside air getting into the system downstream from the dryer. Is the compressor on 24 hours or do the lines drop to normal pressure at night? I have seen problems at another facility we had where the compressor was shutdown at night and we would get condensation in the galvanized lines. We figured it was some point in the system that was drawing in outside air when the pressure dropped to normal, although we were never able to confirm that.

Gregory Sent: Friday, April 20, 2001 8:31 PM To: [log in to unmask] Subject: [TN] Compressed Air... Hi All, I've become involved with our facility compressed air. We seem (in my opinion) to have an excessive amount of moisture in our air lines. There is an air dryer installed downstream from the compressor, but the water traps that are installed at various locations on the production floor need to be drained regularly (sometimes daily). My take on this is that the air drier that we have either isn't functioning properly, or that it doesn't have the capacity that we need for the demand of air that we require. I'm being told by our "Plant Engineer" that there isn't anything out there that will eliminate the moisture from our compressed air lines, he says we're always going to have water in our compressed air lines...I beg to differ with his opinion. Would any of you please post something that says that it is possible to have clean, dry, compressed air on your production floor? This is air that is supplied for our automation, and everything else..... I know that this is possible, I've worked at too many other companies where one of the last things I had to worry about was the quality of our compressed air, but I have a new challenge now...I see water in the traps throughout the production floor every single day that need to be drained daily (and other things that I don't want to get into), but yet I'm told our air drier is functioning properly, and that it just doesn't get any better....that it's just physics. I'm about to go crazy...please help me. -Steve Gregory- ---------------------------------------------------------------------------- ----- Technet Mail List provided as a free service by IPC using LISTSERV 1.8d To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt delivery of Technet send the following message: SET Technet NOMAIL Search previous postings at: www.ipc.org > On-Line Resources & Databases > E-mail Archives Please visit IPC web site (http://www.ipc.org/html/forum.htm) for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 ---------------------------------------------------------------------------- ----- --------------------------------------------------------------------------------- Technet Mail List provided as a free service by IPC using LISTSERV 1.8d To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt delivery of Technet send the following message: SET Technet NOMAIL Search previous postings at: www.ipc.org > On-Line Resources & Databases > E-mail Archives Please visit IPC web site (http://www.ipc.org/html/forum.htm) for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 ---------------------------------------------------------------------------------
