Exhaust retrofit emission control technologies

ERECA companies provide retrofit exhaust aftertreatment systems incorporating best available technologies achieving maximum reductions in PM and NOx emissions from urban traffic:

  • Diesel particulate filter (DPF) systems - passive and active regeneration systems for PM reduction
  • Combined DPF® and SCR systems - for simultaneous PM and NOx reduction
  • Selective catalytic reduction  (SCR) systems - for NOx reduction


Retrofit technology is

  • field-tested
  • effective
  • economical
  • advanced, available, affordable
  • cost-effective
Technologies like combined DPF® and SCR systems/ SCRT® (Selective Catalytic Reduction Technology) are the most efficient retrofit systems reducing hazardous emissions to them minimum:
