Construction machines and emission cleaning

In building sites and other compound areas, exposure to diesel exhaust may cause health and safety risks and affect the productivity. Local legislation or funded contracts may require effective emission control as well. The upcoming Stage III B and Tier 4 interim requirements will be applied to construction equipment too.

Proventia designs and delivers advanced emission control solutions based on various technologies for both retrofit and OEM installations for:

Wheel loaders
Excavators
Bulldozers
