Wort Heat Exchanger - Counterflow Chiller.
These copper counter flow chillers are a fast way to chill your wort. They have similar efficiency to the plate chillers, however can be easier to clean as they do not have all the small crevasses to trap hop material and other solids. The copper is a very good conductor of heat. These units are 23cm in diameter and about 18cm high. The input and output are approximately 10mm outside diameter.
These can be used with gravity but it is recommended to use with a pump.
