Water

I have a large compressor IR, screw type. I feed the output air to a seperator, and two filters then to a membrain dryer as suggested by my supplier.

However the amount of water flow out of the compressor tank is about a coke cap full every half hour. So that in a number of hours the dryer is failing.

There is no cooling of the compressor line feeding the tank... However the unit set in an area where the temp is maintained at 69 degrees and with 36%rh.

What is the best way to stop this water, better yet what is making it happen.

A note, this unit replaced and pistol unit that did not make this amount of water.

Thanks.

Hello Russell:

A few things about your question puzzle me.

You say you have a large compressor. What is the HP please?

What is the separator you refer to? Is it a tank, a cyclonic filter, a dryer of sorts? As far as I know most rotary screw compressors come with a separator to remove the oil used in the compression process from the compressed air. Is this the separator?

The two filters you send the compressed air to next. Are they a general purpose air filter and then a coalescent filter?

That you are using a membrane air dryer, drying air from a "large compressor" puzzles me. Usually membrane dryers are used to generate a very low dewpoint on limited flows of compressed air. I'm surprised that your vendor suggested one for your "large compressor".

A "coke cap full" of water every half hour is a very low amount of condensate. You say it is the water flow out of the compressor tank. Is this tank before the air treatment equipment you have in place, or after the membrane dryer?

Sorry Russell, too many questions for me to make any guess.

Cheers,

Bill
