Hi -

I'm currently putting together a draft system similar to Kal's. I'll have a glycol cooled draft tower with lines going to the keezeer behind the wall and with the glycol cooling in a small freezer next to the keezer.

Question: Where do you split off the glycol lines to go to the freezer? Also, is the glycol reservoir in the freezer or the keezer? I believe I've seen both..

The way I'm thinking about this is:
1. Insulated beer and glycol lines come out of the back wall where the draft tower is.
2. From there the Glycol line splits off, goes into the freezer where it goes through a copper coil to remove heat, drops into the glycol reservoir and gets pumped back out via the pond pump that is in the reservoir.
3. It then comes back out of the freezer and re-joins the draft line..

Does that sound correct?

Thanks,

Scott

Hi and welcome to the forum!

Lots of different ways to do this, but here's what I do:

- Kegs in a keezer, with the glycol reservoir.
- I split the glycol lines in the keezer, right above the reservoir. The 2 insulated lines to the freezer.

More details:

Thanks Kal!!

So I take it that the split happens on the RETURN line back to the draft system - correct? Are there advantages to storing the reservoir in the keezer rather than the freezer?

Thanks,

Scott

I don't think it matters much, but I believe mine goes through the copper coil and then directly to the tap tower, in order to minimize warmup.

With the way I have it the pour temp is perfect. It may freeze if in the freezer. Every setup is different however, so I suggest you do some tests and choose whatever works best for your setup/flow rate/etc. There are lots of variables in play here that will affect flow rate including tubing length, tubing diameter, tubing material, number of taps, copper coil length, pump power, etc.

Good luck!

Kal
