DIY Chiller

are you able to elaborate on pipe sizes and descriptions? From what I can see, I believe the part list for the barrel may be:
2x 4" PVC caps
2x 1/2" ball valves (SxS?)
2x 1/2" unions (SxS?)
8x 1/2" 90 elbows (SxS?)
2x 1/2" 45 elbosw (SxS?)
4x 1/2" couplings (SxS?)
1x 1/2" male x slip adaptor
1x 3/4" female x slip adaptor
1/2" tap?

Please correct the above information accordingly.
Also what size tubing and material is the refrigerant tubing made of? (This will also help with the gland nut size)
What approximate dimensions is the tubing after being bent to that shape?
How long of tubing did you initially have to buy before bending it?

Don't worry so much about what parts are actually used right now.

I'll post progress pics along the way and let you know what size the plumbing is and you'll be able to assemble a parts list for your own projects.

The refrigerant tubing is 1/2" OD. The gland nut I bought comes with many different glands for different size cable.

Oh, yeah. The tubing was 10 feet long before I bent it up. I had an extra 3 feet that I cut off after bending. I would assume that I used 7 feet then.

The tap is a 1/2" NPT (National pipe thread) tap. I can't remember where I got it from.

While I'm posting. I should let everyone know that Friday is the next planned build day. We should be able to get it mostly done and maybe get a frosty coil pic before I close the barrel up. I'll try to remember to do that. Everyone seems to love those pics.

Any other requests for lots of pics of a specific part of the project?

I'm working on a design for a chiller that is self contained. Should make it easier if someone wants one shipped to them. I've got most of the major parts for it. Just need to get a few other things and build it, I guess...

Anyone want to try one out for cost of materials?

yup one.. what material did you use for the refrigeration loop?

Build day on Friday!

After I get home from work, the fun begins!

Posts will be put up either Friday or Saturday night.

The refrigeration piping is a material that Hightower researched and would like to try. He'll be able to provide more specifics as to his choice of tubing

Titanium was obvious first choice but because it is so expensive, and not readily available and after alot of research we decided to go with stainless steel 316L.

I read a ton of posts on it, and SS wins. Hey if this stuff can go inside the human body, its good for fish too.

Hightowerhow much was the SS tubing that you bought? And where did you buy it from?thankschin

Refrigeration supplier from Karl. He's got the connections. Aroudn $4-5 /ft I think
