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!
- Mount the RIMS tube about 1/2 way up the side of my mash tun so that it self floods when I add my initial strike water to my mash.
- Self-purge air out of the RIMS tube.
- Make the RIMS tube self draining even though I probably will continue disassembling & cleaning it.
- Make it easily to disassemble for cleaning.
- Mount the RIMS tube in a location that's out of the way but is also convenient for cleaning.
