The SlingBlade is an innovative electric heating element designed to promote a rolling boil and even heat distribution.
Shaped for Performance and Convenience
The SlingBlade's unique crescent-shaped design positions all of the heating power on one side of the kettle, sending thermal energy upward to the surface that then cascades downward on the opposite side of the kettle. This movement creates a dynamic turbulence that evenly distributes heat while creating a vigorous, rolling boil. Other heating elements stick right out into the middle of the kettle or use a full circle design that rings the kettle wall. This can cause an obstruction for immersion chillers or make it difficult to stir without banging into the element. We designed the SlingBlade to avoid these issues. By remaining on one side of the kettle, the element will be out of the way of your immersion chiller, and since the element follows the curvature of the kettle wall, it won't interfere with the flow of wort during whirlpool.
Ultra-Low Watt Density
An electric element transfers power to your wort by applying heat, but if this heat is too concentrated you will get local heating that is hotter than 212°F. This catalyzes Maillard Reactions, which can lead to darker beer than intended and produce unwanted caramelization. Think of these reactions like roasting a marshmallow. First it gets a light brown, we call this Maillard reactions, a little hotter and it gets a dark brown, we call this caramelization, then it turns black and we call this pyrolysis (burnt or scorched). While all kettles undergo these reactions, an electric element can concentrate more heat into a small area, which can quickly scorch your wort. Our experience is that at 90-watts per square inch recipes need to be modified to account for the element and light beers never come out quite right. The SlingBlade element was designed at 50-watts per square inch to reduce the chance of scorching while still providing a vigorous boil. For even lower watt density, consider the Boil Vigor Controller.
Our heating elements are designed to install quickly and easily on any kettle with a T.C. ferrule thanks to the curved, non-circular design. This also makes it a breeze to remove the element for cleaning between uses. While intended to fit seamlessly with BrewBuilt brewing kettles, you may find them suitable for other kettles as well. They should be used with T.C. ferrules no longer than 1" in length. For dimensions and recommended minimum kettle diameter, please see the chart below.
Please note: Length is measured from the tip of the heating element to the T.C. connection. Radius is measured from the middle of the T.C. connection to the outermost edge of the element's curve.
