Fermentap's stainless steel kettles are restaurant quality - featuring a tri-clad bottom of a 5mm layer of aluminum sandwiched between two layers of stainless. The tri-clad bottom reduces any potential scorching and also make the kettle much easier to clean. They are also punched from a single sheet so there is not interior weld line. But the really cool feature that sets these apart is the fittings we weld into these kettles. The bottom fitting has male threads on the outside and female threads on the inside. The female threads allow your customer to add all kinds of stuff on the inside - screens, pick up tubes, or whatever else they can dream up. We also include a 2 piece stainless steel ball valve. The welded in thermometer port comes with a plug but allows for an easy up sale to a dial thermometer. Note: While most of you probably know this, we would like to remind that the ball-valve should be boiled separately before each use or broken down, cleaned and sanitized. An intact ball-valve left on a kettle is a bacteria harbor and a common source of contamination. You would think the heat of the boil would kill the bacteria behind the ball but this is not often the case. Wall thickness is 1.2 mm and the bottom is 5 mm. This kettle is 20" Tall x 19" wide.
