Nice work. Some thoughts for version three: I assume you've filled the system with some more glycol so that the entire condenser is submerged, but if not, I think you should as the system should function more effectively as there would be a much larger "active" surface area exchanging heat from the glycol to the condenser. Also, since you are using the system to cool the fermenter to pitching temps, you could consider increasing the size of the glycol reservoir so that there will be a large volume of fluid that can be used to cool the wort instead of relying on the continuous output of the AC unit.
Very cool video. I'm wondering if there's a reason the system needs to circulate constantly, or if it would be okay to have the pump run only when at least one of the tank solenoids are open?
How has the manifold and chiller been working? Any problems? Any more updates or changes? Would you change anything if you built this again? I ordered a pair of the valves you used. I plan on building my manifold once glycol pack arrives. How do you think this manifold would function if I built it vertically? The outs to the 2 fermentors on the ascending side, pressure gauge in the lateral section with a restriction valve next in line, then both returns from fermentors on the descending pipe, then back to reservoir right below.
everything still works great. i havent used it as much since it has been cold. the only thing i would change is the chiller. it works fine but i would like to have a actual glycol chiller. i think it would work vertically. i just used a diagram that i new worked but im sure there are other ways to do it.
This video is super helpful. I'm planning out my future brew shed and wondered about getting several fermenters going with different temps. Just curious, are you guys still running the brewery? Hope so:-)>
Just wondering where you got the updated solenoids from and how much? What kind of power source did you wire them up to and where did you get those? Great looking system!
im amusing your talking about the solenoid valves. i wired them to a cord end that plugs into the outlet and the outlet is controlled by the Johnson controller. that way if anything happens i can just unplug the valve and it will stop flowing. also there is not a ground that is why there is only 2 wires.
you should not have the inlet to the cooler above the pump, you should have it in the other corner of the cooler so the glycol water mixture have to travel to the other corner of the cooler where is the pump, so it will have more time to be cooled by the element.

Yeah I was thinking the exact same thing.

recirculating keeps the Glycol and water from separating because the water will freeze if it does

not as much as i would like but we are still brewing on it. i hope to start some new videos soon.

Thanks. I got them on ebay and they are 120v so they just plug into the outlet thats controlled by the Johnson Controller.
So the ones I got have 2 wires out only. You wired them to a standard plug or directly into the Johnson controller?

That's alot of cooling line even insulated is alot to ask for your chiller
it works great!
