This 3″ diameter x 28″ tall Copper Reflux Column comes with a Dephlegmator (used to control proof), a 3/4″x25″ liebig condenser and a commercial grade thermometer with a 3″ face. This also comes with the 3″ tri clamp and gasket for attaching the column to your still. This column is capable of distilling 130 to 180 proof. You can make Fuel Ethanol with this column in 1 run. All of our copper columns are Tig welded using Food Grade DHP copper welding rod. This means that the welds are as strong or stronger than the surrounding metal This DHP copper rod melts at around 1,700F while the Solder that our competitors use melts at around 400F. Solder joints are not nearly as strong as our welds, plus solder is messy, runs and gets all over the metal, while our welds are tight, clean and pretty. This copper pot still column has a 2″ stainless tri clamp ferrule that will attach to any of our 3 to 8 gallon boilers. Comes complete with operating instructions.

• Commercial grade thermometer with a 3″ Face.
• 3″ Tri clamp stainless ferrule connection welded to the base of the column for connecting to a still.
• 3″ Tri clamp and gasket for connecting the column to the still.
• 3″ Tri clamp Dephlegmator connection with 2″ Tri clamp and gasket.
• Removable copper liebig condenser.
• Two 5/8″ hose barb connections on the Dephlegmator for cooling water.
• Two 5/8″ hose barb connections on the condenser for cooling water.
• Super heavy duty construction using food grade copper welding rod and heavy gauge copper.
• Enough copper packing to fill the column.

This item comes with a 1 year warranty which covers manufacturing defects and leaks.

DETERMINING TRI CLAMP SIZE

Tri Clamp sizes are determined by the outer diameter of the pipe or tubing, not the outer diameter of the flange or Tri Clamp itself. The flange of a Tri Clamp fitting typically has about a inch greater diameter than the outside diameter of the pipe. This can become especially confusing when the Tri Clamp fitting has no pipe attached to it, as is the case with adapters, For instance, a1.5″ Tri Clamp to 1/2″ hose barb adapteris not 1.5″ inches in any dimension, but the Tri Clamp end will fit any other 1.5″ Tri Clamp fitting.

If you have any doubts about what size Tri Clamp fittings your project needs, simply measure the outside diameter of the flange (dimension “B” below) and consult the chart below, or feel free tocontact us.
