My conical fermenters use a system of cooling called the "Peltier effect." By running an electrical current over substrates of different metals, a thermodynamic effect is created causing one side of the system to become freezing cold, capable of producing ice, and the other side becoming extremely hot, capable of boiling water. By placing the cold side against the fermenter, I am able to cool my wort to fermentation and even lagering temperatures without traditional refrigeration.I had noticed recently that "Betty," my original fermenter, had lost her capacity to cool wort for fermentation. After a bit of research, I ended up ordering new semiconductor peltier chips, deconstructing the unit, and rebuilding it in a way that was more efficient than the original design. Now, my 12-year-old original conical is more efficient and more capable of cooling wort than ever... Because science!

Boom!
