Internal Reflux Still

The Condenser Core

Refinery Upgrade Tesoro, Hawaii From Energy People

 

The condenser core is the innermost tube that runs inside the water jacket of the condenser. It’s made from a piece of 1" tubing and two copper fittings.

Then brush on some flux to both pieces before soldering, and use lead-free solder on all joints.

When you heat the joint enough with a torch, the solder will be sucked up into the joint. While the solder is still runny looking and shiny, wipe the joint with a clean rag. Makes a nice finish on the joint. Then solder a 1" X ½" reducing coupling on the other end in the same way. When you get done, it’ll look like this:

This is a good time to run a brush or wet cloth through the core to clean up any flux that may have run into the tubing and fittings.
