Air Dryer Problem

[madman]

Well im trying to forget my electrical shop feed woes., Now tonight (sunday) i finally fired up my air nitrogen plumbing system, Had a couple leaks surprising enough as i used big air hose and some Mikalor Hose Clamps a rather sturdy looking clamp indeed. Now i plan on gasket gooing the fitting and resealing it to stiop that small leak BUT now the darn ULTRA AIR REFRIGERATED AIR DRYER Unit . I pressurized the air system following the recommended start uop procedure for this unit. Then when pressure was up i opened only the inlet valve to the dryer (there is a valve for inlet outlet and a bypass main in between those two. NOW the manual says turn ON position and let run for 5 minutes. NOW the auto drain unit mounted on the front of this unit (which of course the instructuion book says nothing about and neither is a picture of the drain unit on the front of the owners manual either??) discharges a blast of air near every minute, thinking this unit had to build some pressure i let it run over a half hour extremely noisy, Anyhow i ended up turning it off because it was pissing me off. Any ideas guys ? Do air dryers dio this for a while or ........... thanx Mike

The air dryers I have been around/used had a float operated valve that would trip on a rising fluid level and blow water until it emptied and then quit. Is you dryer eletrically operated? if so - can you set a timer to make it run less often?

As it is now working it might be great during June, July & August down in the Rio Grande Valley where I now live. But them the Humidity is right around 100%.

If it is working right you should not get much air blast from the dryer - if you are getting only air and no water it is just wasting air and not doing much else.

What is the relative humidity where you are located?

Mike,

I have only seen two types of auto drains used on dryers. One type is float operated as mentioned in the above post. The second is electrical with a timer, either built into the drain valve, or in the control panel for the dryer. The electrical type are the most common in my experience. Check for an adjustment on the drain valve its self. If electrical and has an adjustment you will have to play with it some to find a good time setting, to short and it will waste air, to long and it will not drain good enough.

Hope this helps.

Mike,

the electrical timers for the dryers i work with ,have to be unplugged, then reconnected after ajustment to accept the new settings.

Yeah it has adjustments but the manual said squat about it. I am gonna fiddle with the little adjsstments on the front. Will have to bring my magnifying glass. Thanx for the tips Guys.

Mike,

You probably already got it figured but, the adjustments are going to be 1) time delay between drains and 2) the length of drain.

Let us know how it worked out.
