Hi everyone!
I have the following problem:
I've installed a dry cooler (water in about 80 ºC, water out about 60 ºC) but it's in a mill that works with a lot of thin sand (like dust).
Now I have a lot of "dirt" in the aluminum fins and copper tube (the fin spacing is really tight).
Does anyone have/know where I can find a table that allows me to correlate the amount of "dirtiness" with the lost of capacity...(or pressure drop)...?
Almost like a fouling factor?
Best regards and thanks in advanced,
RAntunes.
