Hi guys, I'm in the process of gathering equipment for a nanobrewery. We bought some BOP equipment and this was part of the pile. We're not sure if this is an inline carbonator or oxygenator. We haven't been able to get much help from the manufacturer-likely due to the fact that there is no serial number listed on it. There is a stone that is 8 to 9 inch air stone inside with a massive hose coil wrapped up inside it. Any help would be much appreciated. Cheers!!!

Is this thing a carbonator or an oxygenator? HELP!

I sent pics to them last night. They said that it's an old piece of equipment and the guy I dealt with had been there for 15 years and they had never carried anything like that in his time. He's going to dig a bit for me but without a serial number, it'll be difficult to find anything.

It's a carbonator. No reason why you couldn't use it for oxygenation, though. Gas is gas
They were plated for Criveller, but I'm pretty sure they were made by Simonazzi. Nixon made one like that, too.
The coil is there to chill the product, which allows it to absorb more gas, if you remember your Charles' Law. Or Combined Gas Law in these (humbug!) modern times.

Not sure what the tube internal diameter is, but a couple of thoughts.
Firstly the flow rate through it needs to be at turbulent flow rates - 1.5 metres / second, ideally 2 metres / sec.
Secondly, for rapid CO2 absorbtion, the back pressure in the tube needs to be around 3.5 bar.
Thirdly, the gas bubble diameter needs to be small. If it is a carbonator, the bubbles will almost certainly be too large for oxygen and the bubbles will take longer to dissolve.
Fourthly, make sure you can clean and sterilise the wretched thing properly, especially all the way through to the injection point on th egas supply side.

that thing looks like it might be more trouble than its worth....and way overkill for your operation if you are just a nano. remember, just because it was tossed in with a pile of other stuff you bought doesn't mean you have to use it....Scott LaFollette

I'm not a huge fan of inline carbonation on a small scale, but that's just me. I've personally never used it but it seems like by the time you get it dialed in you would be done with the batch and potentially have very inconsistent results. I would rather use a brite tank but again that's just me...Scott LaFollette
