  • inline oxygen kit

    In my research on an inline o2 kit, the Morebeer and Gwkent seem to keep coming up.
    But wondering if something cheaper like option 3 or 4 would be just as good or if there are other options...

    1 - https://www.gwkent.com/inline-micro-...m-1-1-2in.html

    2 - https://www.morebeer.com/products/wo...al-series.html

    3 - https://www.ssbrewtech.com/products/oxygenation-kit - says its for their chronicals, but I dont see why it wouldnt work for other fermenters.

    4 - https://www.homebrewing.org/Ruby-Str...it_p_5890.html


    I dont mind the extra $150-200 bucks if the Morebeer or GW kent is superior, sanitary, etc.

    This will be hooked into a 3 bbl system.

    Stout Tanks from Portland has a 1.5" tri-clamp based model for $195

    This Oxygenation Aeration Assembly is used for wort aeration. It attaches directly to the TC fitting on your wort chiller/heat exchanger. Shop Now.


    looks pretty much the same as like the one that came with my 15Bbl brewhouse.

      Is there a need for a check valve at the threaded connection?

        Some people would probably debate whether it's necessary or not. Myself I like there to be a little bit of clear gas line before the check valve, so then I can physically verify if anything has seeped past the stone. I figure replacing 6 inches to a foot of gas line is cheaper than a possible infected batch.

          [I realize I'm reviving an ancient thread, and there are a gazillion O2 threads, but this is the closest I could find to my question.]

          My question is about oxygenation system pipe diameter. (Mostly. See at end.)

          I see tons of info about Lpm of oxygen flow, but have not been able to find anything about wort flow through oxygenation. It seems to me that X-L/min of O2 pumped into Y-gal/min will oxygenate far differently than X-L/min with a pump rate of 2Y-gal/min.

          (Am I right so far? Or starting with bad assumptions?)

          We're just getting started on a 3.5bbl system and we've been looking at all the various oxy systems mentioned in the OP and follow on. It seems that the MoreBeer & SSBrewtech use 1/2" pipe (on a 1.5" TC), whereas the GWKent looks like 1" or bigger and the Stout also appears to be a 1" pipe. We're planning on 1" hoses (with matching pumps) throughout.

          Given that PV=Nrt -- and, so, V = Nrt/P -- and beer is [mostly] incompressible, it seems that half the pipe radius would cut our flow rate quite a bit. Or double the pipe would open it up quite a bit.


          My questions:
          Q1) Either way, if I'm hoping to get a decent flow rate, I probably want the bigger O2 system piping -- like in the GWK or Stout systems -- yes?

          Q2) When people talk about setting their flow gauge to N-L/min of O2, against what wort flow-rate -- how many gal/min -- is that?

          Q2b) ...Or do y'all just do the thing where you turn up the O2 until you can see bubbles in sight glass, but none (or barely any) of the surface of the fermentor, assuming the rest is dissolved on the way?

          Thanks!

            I would suggest that you use clean, filtered air, NOT oxygen, and aerate your cool wort without a worry about flow rates. Rotameters are calibrated for a certain gas, at a certain temperature, and at a certain pressure. None of which you are likely to match. So quantifying the exact amount you think is being dissolved is not easy. Nor necessary in most cases. Air saturated into cool wort will give you just about enough O2 for proper yeast health. Pure O2 can be overused, is expensive, and the only way to get perfect results is trial and error. I don't see any advantage to pure O2. In many cases, I'll skip the whole aeration process and use dried yeast. Easy-peasy. You've likely many other issues in a brewery startup that are more important.
