A premium counterflow wort chiller made with 25 feet of 3/8" OD, 304 stainless steel.
The Mash King Stainless Steel Counterflow Wort Chiller - 25' x 3/8" is built as a coil-within-a-coil. It is designed to chill your wort by pumping hot wort through the inner coil, while cold water is ran through the outer layer surrounding the stainless steel coil. Having the water enter through the end where the wort exits further maximises the heat differential between the cold water and the hot wort. While this chiller can be gravity fed, a high-temp pump is recommended.
