Chill your wort in half the time with the Convolutus Counterflow Wort Chiller, an innovative and water-efficient device designed to use with just about any of our most popular brew kettles. This unique counterflow wort chiller is designed to cool your wort in much less time compared to a standard immersion wort chiller. This high quality chiller is made up of 12 feet of 5/8 inch convoluted copper, which continually spins the wort as it flows through the pipe. The outer tube is made of 7/8 inch copper for added durability. The Convolutus Counterflow Wort Chiller enables you to pump wort through the inner tube, while running cold water in the opposite direction in the outer tube, making the entire process quicker and more efficient than ever before. Use inch tubing and hose clamps to connect the chiller to the wort in and out feeds. The water connections are male and female inch hose connections, and the coils themselves are about 6 inches in diameter. This counterflow chiller is also available with 1/2 inch FPT fittings. 10 1/4" height by 11" overall diameter (coils themselves are about 6" in diameter)
