Hi All:
A technical question for any of you with experience with refrigerant dryers for compressed air systems:
Here's my problem:
I have a compressed air system that I cannot seem to get completely dry.
I have a refrigerant dryer with 30 CFM capacity that is leaving water in the main down line (I have a dump valve on that line so I know it's collecting water).
I have another 15 CFM dryer I inherited and was just standing around getting in my way.
Is it reasonable to connect the two driers in series (first the 30 then the 15) in order to increase the capacity of the system?
Do I need to ditch the two smaller dryers and buy a single new bigger one.
My air consumption is estimated to be under 12 CFM unless I'm running several machines at once.
The biggest air consumer is the mill at 6 CFM and maybe 8 to 10 if I run the air blast.
Everything else requires very little...1 or 2 CFM (if that) to operate solenoids etc.
My compressor is a 5 HP Gardner Denver 2 stage recip. I'm set at between 120 and 150 PSI at the tank.
The bigger dryer was checked out by a refrigeration technician a month ago and was pronounced in good health but I've noticed it's stopped discharging water out the discharge tube, so now I'm unsure about it.
The small dryer is now in the line but it doesn't seem to be doing any better to keep the whole works dry.
It was definitely working when it was pulled from service a year ago.
Cheers
