I was inspired by several of the pump in a toolbox threads and the Simple brewery thread, so when I got a march pump for xmas I wanted to build one.
My 3 tier setup is gravity fed, so the main purpose for the pump is for mash temp control and recirculation, and also recirc for the BK when it comes to immersion chiller time. Somewhere down the line I will make a change to a single or 2 tier setup that will be all electric. For now though, I need to work with what I have and use this RIMS as a learning tool so I can get a better understanding of using PID's. Also, the RIMS could go anywhere 110 is available, so I could take it to a brewday, and stub it in to just about anyone's process who might like to try it out (once I have it dialed in, of course)
I got the RIMS tube from freddyb, he's used it with success and so has lehr. It has 3/8" stubs so I got 3/8" compression to 1/2" NPT adaptors, tees, bushings etc from bargainfittings. I bought an Auber PID and RTD, and have a SSR which I need to source a heatsink for.
The reason for my post is trying to figure out the routing of liquids. I was thinking about mounting the RIMS tube on the outside of the tool box, where a short piece of silicone could make a 90˚ to the pump which is mounted on the end of the box. Right now the pump head is rotated 90˚ but I will probably rotate it back to horizontal, as even with the 90˚ fitting, it hangs lower than the box itself. I may have to scrap this box and go for something a bit larger.
So. Should the wort go in the RIMS first and then through the pump OR pump then RIMS? If I can mount the RIMS to the back I could put the pump switch and PID on the front side of the box, with the SSR sink hanging out of the opposite end of the pump head.
Comments, questions, concerns, and advice are all appreciated. I have no idea what I'm doing with the PID, but I have read RIMS for dummies and any other RIMS related threads that I've seen here.
