Inline Oxygenation Assembly (Stainless)

In Stock
60 day no hassle return policy. Details

This completely stainless, inline oxygenation system injects oxygen into your wort as it travels from your wort chiller to fermenter and allows you to read the temperature coming out of your wort chiller at the same time. It has a 3" Dial Stainless thermometer and a 2 micron diffusion stone. The inlets and outlets are 1/2" barb. The oxygen inlet is 3/8". It is the economical alternative to our completely sanitary, stainless oxygen system, PRO30.

How long should I apply oxygen while transferring to the fermenter?We recommend you transfer half of your wort to your fermenter before applying inline oxygen (O2) to your wort transfer.  If you apply O2 the whole time while transferring you are wasting O2.

I want to use a cleaner way then the wand I have. I brew 1 keg batches and the wand is less easy to do correctly

The description mentions transferring half of the wort before adding oxygen. When you do start adding, how much do you add? Is there a recommended pressure or flow rate?
Nathan Lazur on Apr 28, 2018
BEST ANSWER: When you start adding oxygen maintain a pressure of about 6-8 psi. It doesn't take much, as the diffusion stone will do most of the work.

Using it in line with my chiller. Well made and has become an important part of my system

Worked great
Just what we needed, good product for the price, saved us a lot of effort a the time of oxigenation.
What this is, its basically two stainless steel T's joined by a srew coupler, with the hose coulpers on their respective side, and on one end is the small hose coupler for the gas hose, which has the dufuser stone welded inside (you can unscrew for cleaning after use), and on the other end has the themometer, which is just a great feature to include right there.

Used fro the clubs 20 gallon system
We built a 20 gallon brew system and included this as we exit the HERMS and pump into the building to the fermenter.
The function is good although we had to relocate it into the building after the test run. The stone is now located above the fermentation area.

Needs a little refining..
This piece is a great tool .. But , the first time I used it in a test run of just water, the unit was not able to allow water to pass through. I took it apart to find that the oxygen stone was screwed in so far that the head was gground down from there not being enough room in the t- joint it is screwed into .. Creating no way for liquids to pass threw it .. I believe that a spacer is need to give you more flow .. I had to add a ?_ inch fpt to ?_ mpt adaptor . That seems to be the fix it needs other than that the unit is great and can easily be modified to fit your needs ..

Great Product
Used this once so far. easy to reconfigure different parts to fit where you need. I turn oxygen on half way through filling fermenter.

The simpler FE376 may be better for many
I purchased the unit without barbs, but the review would be the same.

One person complained about the difficulty to sanitize the unit and another said that a pump is necessary, but I disagree. The bottom piece with the diffusion stone is easily unscrewed and boiled, just as one would do with the FE376. Flushing out the rest of the unit is easy and only takes a moment. Then, when you're ready to use it, put the unit (sans the diffusion stone) in some sanitizer. After that, screw in the diffusion stone and hook up your tubing. (While the unit comes with teflon tape on the threads, I don't bother with that and haven't had any leakage problems. After all, you're dealing with minimal pressure.)

The reason I knock it down a couple of points is that wort will enter your oxygen line when you use it. It won't be a lot, but it still requires an extra cleaning step, and it also requires that you set things up so that the wort won't get to your inline air filter. This -- combined with the fact that you're using this while a couple of other things are going on -- makes me question whether it's better than something like the simpler FE376, which you simply use after you have the wort in the fermenter. In addition, even if you have one of these, you might still want to have an FE376 unit to add more oxygen to a high-gravity beer some 12-18 hours after you've first pitched your yeast. This unit can't do that.

Again, the thing works and it's kind of neat to use it, but I think that something like the simpler FE376 unit will probably better serve the needs of most homebrewers just as well.

Time Saver
This is a product that a lot of Professional Breweries used in their pilot systems...It is easy to use and clean providing you are using pumps...I leave mine connected to my Therminator wort chiller the whole time and just connect the O2 hose to it when needed...Makes yeast very very happy...

Nice system in all SS
All in one solution for O2 and monitoring your wort temp out of the chiller. Slight ding on the design since difficult to remove the aeration stone for cleaning.

Seems the design is for those with a pump to back flush to clean. So pick up a pump too!

Great Product
More Beer is the only place I have found with such a Great inline system. I run the wort through a Counterflow wort chiller and then to the in-line system. It reads the temp almost instantly and it is very visible when the oxygen is turned on. No need for a sight glass. This product is a real time saver. Great quality for the price!
