Our products and technologies are used to reduce harmful emissions from older trucks and buses that do not meet the latest legislation.

Our two-, three- and four-way catalysts reduce hydrocarbons (HC), carbon monoxide (CO), particulate matter (PM) and nitrogen oxides (NOx).

We also offer two retrofit products for diesel trucks and buses which can reduce emissions by 90%:

  • The Continuously Regenerating Trap (CRT®) system for CO, HC and PM control
  • The Selective Catalytic Reduction Technology (SCRT®) system for CO, HC, PM and NOx control.
