I dont know if the title peaked curiosity or not but I had a real hairbrained idea recentley and dont have any immediate plans to begin but just looking for any thoughts. I have an old fully functional de-humidifier that Im not using- a freind of mind has custom bike shop and always has trouble in humid weather (like now) with wet compressed air- no drier. I think everyone sees where I'm going with this by now. Do you think its possible to "McGyver" an air drier from a de-humidifier? Obviuosly the main challenge is the re-configering of the evap to some kind of tube in shell deal (?) with an isolated drain. Yes I know it would be 200x easier for him just to buy a drier but I like to tinker. This is all theoretical and i have know real info on capacities, #'s, ect right now.

Not a good idea. You want to try to absorb all the moisture in 100#s of compressed air by moving it through a coil and then back through the rest of the line. Your coil would have to be the size of your shop wall. We have two water strainers in our system and in a conditioned space and we still have water problems. Goodluck.

I did this exact thing using a window A/C and didn't even have to open the refrigeration system.
pull evap coil from dehumidifier and stick it in a bucket of water. stick coil of 3/8 copper tubing in same bucket. run air through copper tubing. on outlet of tubing install a standard compressed air water seperator. Replace humidistat with a temperature control and stick the sensing bulb in the water. Set it for 34 or so.
If he uses a lot of air you will a big water seperator or one with an automatic drain. Its unbelievable how much water a system like this removes.
