A while ago I built a portable stainless steel RIMS tube and I published this instructable outlining the process so that others could build their own. As a result a lot of customers asked if we were going to offer a RIMS tube kit. After about 2 months of saying no, I went ahead and started selling kits. I really did not think they would sell but I was wrong and now we sell RIMS Tube kits ob Amazon.com.
My original portable RIMS tube is not without issues, all relating to water and rust. Because the RIMS tube is vertical water can't drain past the bottom barb fitting. This is easy to take care of by tipping the RIMS tube on its side to drain, then once the water is drained you just disassemble the top from the bottom and wipe out the remaining water with a paper towel. But this brings up the second issue - rust. Leave water in your portable RIMS tube too long, as I did, and the surface of the threaded heating element will rust! It took a while but we figured out a potting process with food contact safe epoxy that takes care of the rust issue. This instructable shows you how to pot your heating element to reduce the possibility for rust.
Now I have a three tier brew stand and I wanted to mount my RIMS tube on my brew stand but at the same time I wanted to solve the issues I had with my portable RIMS tube, otherwise why not just continue using my portable RIMS? My new brew stand is made of 8020 T-slot framing, which along with their fasteners makes mounting just about anything a easy task.
I had a set of goals and I believe I achieved all of them this time!
One nice thing about our electrical boxes is they make mounting our RIMS tube easy.
Also, 8020 has some neat little captive 1/4X20 nuts you just shove into the T-slot frame. They have a little rubber nipple you grab onto when inserting them and the other side of the nipple helps hold the fastener where you want it. I also chose some short 1/4X20 allen head screws to mount the RIMS tube.
