Convoluted counterflow chiller (5/8" diameter inner tube, 1/2" NPT female fittings, water hose connections)


We use and recommend a copper convoluted counterflow chiller over immersion chillers and plate chillers as we feel they are the best compromise between performance and ease of cleaning while minimizing limitations on how or what you can brew. With a counterflow chiller small portions of wort are chilled instantaneously from boiling to yeast pitching temperature. This locks in hop flavour and aroma and limits excessive dimethyl sulfides (DMS) which can cause a 'cooked corn' taste and aroma in beer.

For more information and recommended fittings / attachments, see our Wort Chiller guide.

Mounting bracket pre-installed.

Note: Stainless steel versions also exist but they are slower at chilling as stainless steel has a lower heat transfer coefficient (i.e. is less efficient) than copper. This difference will be most noticeable when there is a great difference between the two fluid temperatures (as is the case with how a counterflow wort chiller is used to chill boiling wort using cold tap water). This difference in materials performance is negligible however with our stainless steel HERMS coil.



Inner tube: 12 feet of 5/8" convoluted (twisted) inner copper tube for maximum performance (the wort is continuously turbulated as it flows through)
Outer tube: 12 feet of 7/8" copper
Wort connections: 1/2" NPT female
Water connections: Male and female 3/4" water hose connections
Dimensions: 10-1/4" high, 11" wide (coils are approximately 6" in diameter)
