32 Coils -30 Inch Length X 1-15/16 Inch Diameter Fits Inside All Thick, Medium Or Thin Walled 2 Inch Copper Pipe Condenser Column For Maximum Copper Surface Exposure. This Method Creates 230 Sq. Inches Of Soft Copper Coil Ionization Contact Area Providing Smoothest Flavor Of Liqueur And Brandy. It’s interesting to note that this design of heat exchanger is remarkably efficient, and requires a surprisingly slow trickle of cold water to thoroughly condense the vapors.
Here Is An Example Column Still Condenser Worm Image From The Book 'MAKING PURE CORN WHISKEY A Professional Guide for Amateur- and Micro-Distillers'
Exception: Coils Are Spread Apart To Create Vapor Turbulence For Longer Contact With Copper Surfaces. Cold Water IN Is On Coiled Side For Max Performance.
Happy Building!
