An aftertreatment system comprises a SCR system. The SCR system includes a housing having an inlet, an outlet and defining an internal volume. At least one catalyst can be positioned within the internal volume. A mounting support is positioned around at least a portion of a perimeter of the housing.
An aftertreatment system comprises a SCR system. The SCR system includes a housing having an inlet, an outlet and defining an internal volume. At least one catalyst can be positioned within the internal volume. A mounting support is positioned around at least a portion of a perimeter of the housing. A heat shield is positioned around the perimeter of the housing such that the housing is positioned substantially within the heat shield. A portion of the heat shield is disposed on and in contact with the mounting support. A clamp is positioned around a heat shield perimeter. The clamp is positioned on the portion of the heat shield disposed on and in contact with the mounting support. The mounting support is configured to transmit a clamping force of the clamp on the heat shield to the housing to prevent buckling of the heat shield from the clamping force.
