The Difference Between Canned & Uncanned Combustors

Our ceramic catalytic combustors are used for wood burning applications. But what's all this business about canned and uncanned? Let's see if we can clear up the difference between the two:

CANNED
A ceramic catalytic combustor is wrapped with a welded stainless steel strip. In addition, a gasket material has been snugly fit between the combustor and the "can." Certain applications that utilize this style of combustor may or may not require an additional interam gasket outside of the can for a secure fit. If your canned combustor does in fact have the extra gasket around the exterior, you should replace this component as needed. CLICK HERE for interam gaskets!

UNCANNED
Simply put, this is a ceramic catalytic combustor that is not wrapped with a welded stainless steel strip. This particular type of combustor does require an interam gasket wrap. This lightweight, flexible gasket is 1/16 inch thick and is available in 2 or 3 inch widths by the foot. The chemically bound water particles in this soft material expand when exposed to high heat, therefore cooling off the combustor and protecting your application from overheating.

While there is no real rhyme or reason as to why some manufacturers use canned vs. uncanned combustors, or why some manufacturers use an interam gasket on a canned combustor and others don't, it is important to replace these components per the manufacturer's specifications. (For example, if your application originally housed an uncanned combustor, you should therefore replace it with an uncanned model, and so on.)
