After many weeks of anticipation, I got the completed heat exchanger back from the welder. I think it is one of the coolest things I’ve seen.
Some things that ended up different than my design are: Coil Diameter is smaller and therefore takes up more height in the chamber and make a taller chamber necessary, RTD port is on the side to not be too close to the element.
I hope to do some leak and maybe some ramp testing on it this weekend. I probably won’t brew with it until I can get the set points and RTD positioning figured out though.
For all non-believers that said it couldn’t be built, here are some shiny picts.
Here you can see the tip of the RDT sticking out:
Here is the lid:
Lower coil enry point:
So my question now is, do I configure the out flow vertical like this:
Or horizontal like this:
I think I need a way to ensure all air is purged and there is no bubble trap while still being able to completely drain the line for storage.
