The BrewBuilt 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. The SlingBlade was designed 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.

Tri-Clamp Connection
The SlingBlade installs 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. The SlingBlade heating elements were designed to fit perfectly with BrewBuilt brewing kettles, but 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.


  • Made from Stainless Steel with proprietary coating for long life
  • 1.5" Tri-Clamp connection
  • Unique offset design promotes rolling boil
  • Ultra-Low Watt Density eliminates scorching
  • UL Certified components


  • 240 Volt
  • L6-30 plug
  • 20 Amp breaker required for 10 & 15 gal element
  • 30 Amp breaker required for 22 & 31 gal element
    • 50-gallon kettle requires 2 x BE538 and 2 x 30 amp circuits

SKU Kettle Vol. Wattage Length Radius Min. Kettle Ø
BE535 10 gal 3750 13.25" 6.3" 13.75"
BE536 15 gal 4500 16.75" 7.3" 15.75"
BE537 22 gal 5000 17.25" 8.3" 17.75"
BE538 31 gal 5750 19.5" 9.3" 19.75"

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.

Any plans to offer these with a 2" Tri-Clamp connection?
Anthony Dockter on Feb 12, 2020
BEST ANSWER: Anthony - Apologies, this is not a plan as of right now.
How do you prevent rust/corrosion on the element?
Robert Knipper on Mar 6, 2021
BEST ANSWER: The best ways we have found to avoid oxidation of heating elements is to clean them thoroughly immediately after use, spray them with a light coat of mild acid sanitizer, then put them away nice and dry.
What is the best size to go in a keg 15gal sanke?
John H GRIMES on Jul 25, 2021
BEST ANSWER: It depends on the inside diameter of the Sanke keg. I don’t know off hand but the BrewBuilt website will list the minimum keg diameter that each size sling blade fits.
Will the 5750 watt Slingblade fit into a 22gal BrewBuilt kettle?
David Bowes on Apr 3, 2021
BEST ANSWER: No. The 5750 watt element is designed to fit the diameter of the 31 gallon kettle only. For the 22 gallon kettle you will want the 5000 watt BE537 element.
Is the 1000 watt difference from a 5500 to the 4500 that big? I’m thinking along the lines of getting the wort to a boil?

This is a great product. Fits perfectly in my Keggle and allows my immersion chiller to fit all the way into the wort. Heats 10 gallon batches well.

Solid Element
Works as it is supposed to. Nice rolling boil and leaves the center open for trub or other accessories. I have it paired with the Blichmann power controller and I get a solid boil at about 85% with 14 gallons of wort.

This thing allowed me to keep my SS Brewtech BME Kettle when I switched to electric brewing.
I was looking around for an element that I could make work with my SS Brewtech BME kettle when I moved to electric brewing. I love that kettle and was looking to keep it, but I was having issues finding an element that would fit it. In order to make this kettle work in an electric brewing setup, I had to put the element above the heat shield (which is at the 4 gallon mark of the kettle)... not fun when you try to boil liquid from over the halfway point of the total volume.

Enter the slingblade. This thing saved my bacon from having to buy a new kettle. With just a tiny bend I was able to get it to fit my BME kettle. It now contours down to the 1-1.5 gallon mark near the bottom, allowing me to retain my kettle yet still get a thorough and homogenized boil. No issues heating up 7.5 to 8 gallons of wort! This may not be the most traditional use of this product, but I'm super glad something like this exists.
