So continuing on with the description. I decided after a few conversations with a brewing friend of mine that it would be best to have an oversized mash tun, and I am glad I followed that advice. I originally was looking at the 10 gallon igloo coolers, but opted to use a full sanke keg for the task.
For a false bottom I decided to go with the Sabco false bottom after reading so many reviews from people discussing issues with grain getting pulled into the pump due to the false bottom not being held down properly or lifting up during the vorlauf. I looked at the Jaybird false bottom, but ultimately it seemed that the price was a little higher than the Sabco, and the Sabco came with the stand attached already.
I bought most of my fittings from bargainfittings.com, got some sight glasses from bobby_m as well as his mash recirculation tube, and I got my pumps from rebel brewing. I opted to go all stainless (wasn't expecting it to be sooo much money for fittings....) and used a 1/2" soft cobber tubing for the HERMS coil.
For the electric portion, I chose to use 120V since I am still somewhat mobile with no permanent brewing location. I also designed it for a 20 amp circuit, but overall, i don't expect to draw more than 15 amps at any given point. I used a 120V 1500W heat stick. The first one rusted pretty bad, but I think that may have been due to some of my cleaning chemistries prior to use. I plan to try a different heat stick before going down the road of a sacrificial magnesium anode.
For the PID controller, I went with the Auber Instruments, and I cannot be more pleased with all its features for the price. I also chose to work with the Pt100 RTD built in to a sealed 1/2" NPT fitting.
My panel is a hammond panel, set to be able to toggle on 2 pumps, the heat, and the PID control.
I am hoping to do a test brew this weekend on this new system. I should post some pictures in a few minutes of the build.
