Not sure I agree with the efficacy of this "gas displacement" method, as gases mix and do not displace very well. Would take lots and lots of CO2, and several iterations, to get a low level of O2, I think. Liquid displacement is a completely different story, and I don't know why they simply don't do what he earlier suggested. But having said this, if living with some O2 (it won't be "No O2"!) works for them, then that's what counts. I've always thought that many people get a little over-paranoid about a little O2, just as they do with sanitation procedures. I know, "get one bad batch, and you'll change your tune". But I've never had one … at least yet.
This is a little old now. More common industry pratice is 3 purges at 15psi. All gasses mix over Time but if you do a cycle in 20mins they are still pretty well separated. Best is deareated water if you have it. No O2 is impossible best recorded DO levels are AB at 0.2ppb. Breweries that do the 15psi 3x purge are getting sub 20ppb which is really good. How are you purging at your brewery and what are your ppb's? Thanks for the comment, cheers!

+nirapsnao Thanks for the encouragement! Here's some quick thoughts. Unitank refers to a standard jacketed conical fermenter with a carb stone. The tank will be used to ferment, carbonated, and package/serve. One FV for multiple uses (Unitank). Advantages: smaller footprint, cheaper start up costs, less SOP's and cleaning, save on CO2. Disadvantages: lose ability to filter, slows brewery production, Yeast and hops will fall off ceiling and walls when packaging, dirty carb stone, No capacity level sight glass, cheers!
Jasper, we are opening a 10BBL brewery of our own and trying to figure out those gas quick disconnects. What type do you use and where do you get them from? Looks like you’ve got 1/2” threaded male to 1/2” inch barbed female down to 3/8” for the gas line. Can you give us exact model#? Having a hard time finding stainless

excelent matte!!! keep doing these awesome videos.
Should do a video of unitanks advantages and disanvantages

Thanks for sharing the video! What type of tubing are you using here for your CO2 lines? Also, what type of quick connects are you using here?
Cheers!
How are you doing now??? Watched this years ago.... Great films
How large is the C02 tank that is needed for an operation of your size? Seems as though you must go through a lot.

A thought experiment. What would your technique be if you did not have pressure rated tanks? Cheers!
Not sure about that
Hello Jasper! Can i get your email address to ask a few questions? 😊
