you can get the same valves jon used from here. they are priced pretty cheap.

Only thing to keep in mind is that they have a different wiring scheme and no manual override (I just received 6 units in the mail from OSCS 2 weeks ago). OSCS were brilliant to deal with, but information on the valves is pretty limited (though I believe the wiring scheme is pretty standard and I'm hoping that they can be used with standard solid state relays).

they should work w/ the relays. The only thing the relays are there for is routing one side of the power or signal to the valves to open and close. the BCS is what will control the relays. All you need to do is route your yellow wire to one side of the relay and the positive side from the 12vdc power supply and you will be good. you can run the blue wire to the stand and ground it or if you power supply has a ground run it there. as for the negative side run it straight to the valve. when you want the valve open the BCS will close the relay and the positive side will be routed tot the valve to open it.

Exactly what I was thinking... I've got the relays, heatsinks and valves ready to go and will be wiring them up soon (doing the stand build in the next couple of weeks, then will take care of the wiring shortly after).

Great system Jon. Very clean and impressive design.

I am in planning stages a very similar 3 pump, 1 tier system to be run by ECC. I'm going with that design for the same reasons you are, to easily enable brewing 2 batches simultaneously. Your design definitely will help me as I finalize my build plans. I have a couple questions about your setup that I was hoping you could clarify:

1. Did you consider hard plumbing for the kettle returns from the pump? I noticed you chose flexible tubing for those connections, while using hard plumbing everywhere else. What are the reasons you decided to use that approach? How long does it take to set up and tear down?

2. How do you control the liquid flow rates, for example during sparge? I'm assuming the controlled valves are only a digital response and are either full open or closed. Do you use the manual valves to adjust flow rate?

3. Do you have anything wired in to control the mash tun liquid level during sparge? A float switch or similar? I don't see it in your wiring diagram unless I missed it.

4. Can you provide more information and / or pictures of the kettle return plumbing? Specifically how it connects to the boilermaker pots, how the liquid is dispensed inside the top of the pot, and what modifications were required.

5. I'm also planning natural gas. What burners did you decide on and do you like them? What parts did you order for the pilot light setup (tubing, pilot, valves, etc)? Have you wired your pilot lights into ECC using the new module yet or are they controlled differently?

6. Similar question on the temperature probes. What make / model did you purchase (ECC or other) and how did you physcially put them into the plumbing?

Any additional information about these items would be helpful. I'm at the stage of starting to create a parts list and cut sheet, so any additional information about the make/model of parts you used would be good as well.

Thanks for the help.

Sure, I considerer it, but did not go that route because I did not want plumbing extending 20+ inches above the top of the stand. Not only would it be fragile and prone to being bent, it would prevent you from flipping the stand over to work on any wiring underneath.
clegg wrote: 2. How do you control the liquid flow rates, for example during sparge? I'm assuming the controlled valves are only a digital response and are either full open or closed. Do you use the manual valves to adjust flow rate?
See pictures - there are ball valves at the top of each kettle for the returning liquid. I chose to put them there instead of down by the pumps so you can make easy flow adjustments while looking at the flow in the kettle. If you put them down low, you have to bend over to make the adjustment, then stand back up to look in the kettle and see if it is the correct rate.

No I do not. I've thought about doing some float switches, but I've found that once I set my flow rate on the return valves that I generally don't have to tweak it much. Thus, starting and stopping the flow automatically has not been necessary.

See notes above and pics in thread. I'll add another picture to show the whirlpool tube inside the boil kettle.

I am using the 6" 10 tip Wok burners. They seem to be getting hard to find now. They are working fine for me. I bought all three used off someone online, and they already had the standing pilot orifice. Each burner has two manual valves - one to adjust the pilot and one to adjust the burner. The solenoid then fires it on/off based on where I adjusted them to.

Temp probes are from ECC. See pics for installation. There is one in a T at the input for each pump and another on a T at the output from the therminator.

Other changes from earlier pics:
- My current stand layout has all the gas plumbing moved to the front. This has been easier as any adjustments to be made to pilots or burners can be done without having to walk around behind the stand.
- Changed 3rd kettle to 20 gallon Boilermaker to match the other two.
- Changed to MoreBeer SS quick disconnects.

Excellent, thanks! Time to get started soon. Planning to start with fermentation control and then work on the brew stand.

By now, I imagine you have a few batches of brew under your belt. I've been following your thread for a few months, as I am in porcess of building my next generation brew stand around the BSC. How is the rig performing? What have you changed, or would you change at this point? ;)

The rig is performing very well. The latest picture shown above had some changes from the earlier ones. Specifically, I changed out all the disconnects to SS ones, added a third Blichman boilermaker and I moved the gas plumbing to the front of the rig instead of the back of the rig. One item that is not pictured is a change I made to my Therminator where it's output loops back to the kettle return. This lets me do the cool down recirc without having to use the extra tubing that was previously coming from the Therminator and hanging back into the top of the kettle. The area that I've put a lot of effort into is my programming. I have got a lot more detailed in my processes. Hopefully after the next update to the BCS, I'll be adding electronic ignition and a hardware based alarm buzzer. I'm still looking at possibly adding some float switches as well, but those are not a high priority right now.

I did a club brew day at my house early in April and one of the members did a short video of the day. You can see parts of the rig in action here. http://www.youtube.com/user/Backhousebr ... -exFecRiVg

Looks great Jon. Did you end up deciding against the switch to electric + RIMS? Still looks very clean despite the gas plumbing being relocated to the front.
