And it makes for some very clean brazing. It also lets you know when the entire tube is leak free because the flames stop. http://ecorenovator.org/forum/attach...1&d=1443789585 |
MEMPHIS91,
This is serious work you're doing here! Thanks for the pix, they help 'make it real'. Keep going! -AC |
Don't use fluorocarbons as purge gas since they can become very toxic if heated to high temperatures.

Thanks AC, I was only able to get the line going into the pond to 2.5 feet. The water from the pond kept me from going deeper. If I do the DX for the 4 ton unit I will be sure to find a way to get it deeper.
I still have a front yard that needs repairing and my field lines from the septic patched back up. |

I let everything settle in the pond, plus we had a really cold night. The temp at the end of the loop is 70F. That is better than I though it would be. I only need the green house to be 65F. So there should be some pretty good efficiency!

I see you have engaged the hyperdrive on this one again. Don't run into any planets or imperials on your way, captain Jake. May the entropy be with you. |
Jeff, I might be making a noob mistake and calling it the wrong thing. When I said purging, I meant the very low pressure gas I use as I am brazing to keep the black soot stuff from forming on the inside of the pipe.
I know purging is also the process of running a higher pressure gas (like nitrogen) through the system to clean out any particles. Sorry if there was confusion or I am just totally wrong on every point. lol I was looking at this though http://www.amazon.com/PneumaticPlus-...ords=air+dryer Thanks man! I should have it up and running next week, I still have to finish the electric fence around the hard red winter wheat I just planted, and put the wood stove back together. WINTER IS ALMOST HERE! :eek: |
Nope, we're all on the same page with this one. Air is the thing that oxidizes the piping from within whenever you heat it up. At phase change, water expands to 1700 times its liquid volume. This why the purging (aka shielding} gas should be as inert and dry as possible, especially when brazing or welding. Most of the synthetic refrigeration gases decompose into nasty and toxic fractions and acids whenever they see high temperature and any moisture present acts as a catalyst (steam cracking process). If you are really poor, go to the party store and get a few balloons filled with helium. BB gun cartridges and paintball gun cartridges are also pretty good and cheap solutions as well.

Thanks for the pictures. I would like to see pictures of your green house and Aquaponics setup.
I would like to know more on what you will use to safely heat the fish tank water with this. Nice work. |
