ARIS® Airless Return Flow Systems

The patented Advanced Reagent Injection System (ARIS) system features a single-fluid return flow solenoid-actuated injector.

Airless injector systems are a cost-effective solution for any SCR or hydrocarbon injection application, especially in transportation where air compressors are not available or in many cases feasible. This results in a system that is more compact, less complex and less costly.

This versatile system is used to inject reducing reagents in applications such as selective catalytic reduction (SCR) and NOx traps, as well as active diesel particulate filter regeneration systems.

  • Unique return flow design with integral cooling allows airless injection of reagents in challenging high-temperature environments such as exhaust streams
  • Compact design with precise injection control and good atomization
  • Single fluid, return flow design not prone to injector clogging commonly found in non-return flow systems
  • Airless nature eliminates the requirement, installation issues and costs of compressed air for traditional air-assisted injection
  • Applicable for mobile (on-road and off-road) and stationary applications
