Single Module Aftertreatment System

The Single Module™ is an ultra-high efficiency aftertreatment system. Previously, aftertreatment systems were designed simply to meet emissions requirements. This system, however, was developed specifically to meet customer needs first, while also meeting emissions standards.

Benefits:

  • The Single Module is designed to be up to 60% smaller and 40% lighter than preceding aftertreatment systems, all while improving emissions reduction performance.
  • The compact size enables better heat management and retention for improved fuel economy.
  • The single-pass exhaust flow design delivers low back pressure.
  • The simpler packaging allows for fewer variations. This allows for improvements in system integration and a more robust and reliable system for the end-user. OEM customers can benefit from simpler chassis integration, as the UL2 Urea Dosing System does not require engine coolant lines to and from the urea injector.
  • The system achieves a more efficient atomization of urea and minimized urea deposits, thus requiring fewer regeneration events while experiencing optimal use of urea throughout the system.
  • Advancements in catalyst technologies have allowed the diesel particulate filter to have a bigger ash capacity, permitting for increased time between maintenance events and minimal operator intervention.

Features:

  • Integrated with the UL2 Urea Dosing System to deliver improvements in NOx reduction capabilities.
  • Offers end-in, end-out (EIEO) and side-in, side-out (SISO) inlet and outlet configurations for added installation flexibility.
