HEATING JACKET COMPOSITE FORMED AS SINGLE SHEET (INSULATION, HEATING AND WEAR PLATES)

摘要

A heating unit and method for use in heating a canister containing a reductant, such as an ammonia storage material to release ammonia for use in an after-treatment device in the reduction of NOx in an exhaust system, is disclosed. The heating unit or jacket is constructed from two sections, each section having an outer shell and an inner multi-layered composite including an insulation layer, a heating element layer and an inner surface layer, wherein when the sections are joined together they form an interior heating chamber. The layers of the composite are formed together as a single sheet.
