Our coils are professionally manufactured by a US stainless tubing company, ready for use in your electric brewery setup. The longer 50 foot length ensures that heat transfer is maximized and the large 1/2 inch tubing minimizes flow restriction. Easy to install even in tight kettles due to the cross-over design as having the ends come from the opposite sides of the coil allows for more flex. Attaches to your kettle using compression fittings. Refer to our Hot Liquor Tank build guide for more information on HERMS as well as installation instructions.
