Emission Control System
PROLONG THE LIFESPAN of your machinery with an easy, cost-effective upgrade! Retrofitting a heavy-duty machine with a new exhaust aftertreatment system makes the machine just as clean as a new low-emission machine.

When public and private tenders require contractors’ machines to fulfill Stage IIIB, IV, or V emission standards, retrofitting your machine with an advanced exhaust aftertreatment system is an approved, fast-acting, and cost-effective way to control emissions and meet tendering requirements.
