Well Cavalry, unless you're feeling to lazy to click on it, here is the link that'll satisfy your curiosity:

I see all kinds of coils in these pics but no brewing chamber anywhere. Also, you might wanna try using stainless steel for that coil. I have heard that the product from a copper coil can make you go blind.

thanks! maybe I will whip one up and put it downstream of my super dryer....see if it catches anything. hmmmmm....

I think if you would put it upstream of your tank you'd get the best results -
between the compressor head and the receiver.

I'm just about finished building a similar Franzonator, out of 2 inch stainless tubing, inside a 3 inch stainless tube, and running 30 degree glycol mixture through the larger tube. There's 2 units side by side. I will try to snap some pics soon, and get them back to you. Sorry, I don't have any pics of the tubes that are inside the cooling jacket, but you can get the general idea. I sure hope it works as good as everyone says it does.

The real advantage of building Carl's Cooler is that, in the summer, cold beer + ice cubes = drier air.

Chill out

I like the way ya think

Cracker, it should help, no doubt.

I added a new setup to receive air right off the compressor and then it's outlet feeds the holding tank.

Mine is a little larger and is basically a tank with copper tube inside surrounded by water, like a basic boiler cooler. Lots more work, but does keep me from having to drain water from the holding tank. I now have very little moisture in the receiver tank after a days worth of shop work, of which all hand tools are mostly pneumatic. The blast cabinet will average a couple hours a day as well. So it seems to keep up fine.

Good clean setup.

Here's a few pics of my air dryer, as I was talking about before. It's made out of leftover milk line, both 2 and 3 inch 16 guage sanitary tubing, and some stainless pipe nipples and couplings. The stand is 1 1/2 pipe, will mount it between the 2 compressors and run the lines to the dryer. Chilled glycol will go through the 3/8 inlets and outlets, and I'm gonna order some 1/2 solenoid valves to put on the drain. Franz was always saying I couldn't tie the 2 drains together, it would work less effectively, but I don't see why not. Anyone know more about fluids than I do? Could I make do with tying them together and putting check valves in in the lines? I drilled the 3 inch to go around the input line, then split the pipe in 2 and welded it back up. The last pic is my screw up of the project. (every project has to have mistakes to cover up, right?) For the output side I transitioned to 3/4 pipe right at the inner tube, so the end caps for the 3 inch were different sizes, one for the outlet, and the smaller one for the water drain. When I drilled and cut the cooling jacket, I measured from the wrong end, so it was backwards. So, had to drill the one side out to 3/4 pipe OD, and then weld some 1/2 pipe OD washers onto the other end. Oh well, it didn't take too long to cover that problem up.

We built a condensor for a holding plate chiller set- up in a sailboat along those lines. It was 20 years ago so I might have the line sizes screwed up but what we did was straighten out 20' or so of 3/8" and either 3/4" or 1" copper tubing and then we slide the 3/8" tubing into the larger tubing. Then we coiled the tubing and tucked it behind the auxillary, which is the engine on a sailboat for you non- stick and rag boat types. We soldered the necessary fittings into this mess and then we plumbed the large tubing into a pump fitted into the sea box and hooked the 3/8" tubing to a York compressor on the auxillary and into a holding plate set- up in the ice box. It took about three days to vacuum the condensation out of the condensor lines. Between the Louisiana humidity and soldering and us running lots of water through the outer tubing to check for leaks we condensed a ton of water into the refrigerant side. The next time I do this I'll worry more about being able to drain or blow the water out of the refrigerant side and less about hiding the tubing.
