This is the unit that comes with our electric smoker, here sold separately. You place your metal tray of sawdust directly on the element which heats it and makes it smoulder. This element can be used to create smoke by gently heating the sawdust or to heat the smoker itself to cook the food.
It can be used with most cabinet type smokers and is often used by people who have designed and build their own smokers. It comes with a 2 pin plug (UK plug adaptor is also included).
