Default Inline Oxygenator

Here is a inline oxygenator i threw together for a club member out of 3/8" tubing and 1" tube with KF flanges. This is meant to be mounted to his brew sculpture and connect with 3/8" ID vinyl hoses for wort and 1/4" oxygen line. The 3/8" tubing was silver soldered to the 1" tube and filed smooth on the inside to eliminate pockets that would cause sanitation problems. http://picasaweb.google.com/kevin.ladue/Oxygenator

Cool! Can you give a parts breakdown for that? I don't know what some of those pieces are.

Have a rough estimate of the cost and or a supplier for all that SS goodness? Very kickass setup, should be simple to keep clean.

Do not know what the cost was as these were leftover from a previous high tech job, you should be able to use the MKS instrument web site and find the local representative or purchase directly online.

So when you are hooked up and everything, what is the pressure that you set your O2 at, or do you just crank it wide open?

Cheers

After 5 years of using oxygen have worked out a flow and time for 6 gallon batches. Oxygen flow rate was .5 SCFM and time duration was 3 minutes which made the yeast perform to spec for each strain tested. High flow rates are a waste of time as the oxygen does not have time to absorb into the wort, just makes a nice foam head in the fermentor. To measure flow have aquired a dwyer flow meter VFA-2 and set flow to .5 SCFM through a stainless air stone to get repeatable and predictable results. Here is a link to the Dwyer flowmeter http://www.dwyer-inst.com/htdocs/flo...A-VFBPrice.cfm
