A panel assembly includes a panel member, a frame member, and at least one first bar member, and at least one second bar member. The at least one first bar member and the at least one second bar member divide the panel member into a plurality of first areas defining a first height and a first width. The panel assembly also includes a plurality of support arrangements for dividing each first area into a plurality of second areas. Each support arrangement includes a first support member defining a first length such that the first width defined by the first area is greater than the first length. Each support arrangement also includes a second support member defining a second length such that the first height defined by the first area is greater than the second length.

Panel assembly and aftertreatment assembly including panel assemblies

An insulation system for an aftertreatment system includes a first insulating element including at least one slit, and a second insulating element including a plurality of fingers extending from opposing sides of an aperture. The second insulating element is couplable to the first insulating element, and when the second insulating element is coupled to the first insulating element, the plurality of fingers overlap the at least one slit.

Insulation systems and devices

A heat shield system for shielding sensors from heat includes a sleeve portion made of heat-insulating material and has a hollow shape sized and shaped to be wrapped about a pipe of the exhaust treatment system. The sleeve has a longitudinal slit and an opening formed through the sleeve. The opening is configured to receive a sensor. The system includes a collar portion made of heat-insulating material and includes a base part configured to attach to the sleeve portion and a collar enclosure that extends radially from the base part. The collar enclosure defines an open chamber configured to surround the sensor and shield the sensor from heat while permitting access to the sensor. A closure is configured to retain the collar portion on the sleeve portion and hold the heat shield system in place.

Heat shield assembly for exhaust treatment system

A heat shield assembly is provided for shielding a wire harness that is associated with a sensor in communication with a heat source. The heat shield assembly includes a base plate having a primary aperture that is configured to allow passage of the wire harness therethrough. The primary aperture is disposed in alignment with a hole defined on a shroud of the heat source. The heat shield assembly also includes a pair of walls extending upwardly from a pair of opposite edges of the base plate. Further, the heat shield assembly also includes a pair of ledge members that extend laterally from a pair of first ends associated with the pair of walls. Furthermore, the heat shield assembly also includes a pair of thermal diverter plates that extend angularly from a pair of second ends associated with the pair of ledge members.
