Compact NOxPAC™ – all-in-one emission system for Stage/Tier 5

Proventia NOxPAC™
NOxPAC™ Stage/Tier 5 SCR system

Proventia’s Stage/Tier 5 SCR emission system NOxPAC™ is optimized to fit even the tightest space requirements. NOxPAC™ allows an AdBlue mixing length of less than 300 mm; the whole system length is less than 650 mm. The short mixing length contributes to the excellent NH3 mixing and high NOX reduction. The sweet spot for NOxPAC™ is engines of 2–5 l and less than 100 kW for off-road machines
