THE UNIQUE FPT SOLUTION FOR OFFROAD, MARINE AND POWER GENERATION APPLICATIONS

To maintain the advantages of the unique and unbeaten HI-eSCR technology, FPT Industrial integrates a maintenance-free filtering device on its SCR catalyst, thus allowing to comply with tightened limits on PM emissions within a compact package. The second generation HI-eSCR 2, applicable for engines above 56kW and below 560kW, where different emission limits apply, will maintain the same after-treatment dimension of the current Tier 4 Final / Stage IV applications, requiring no machine redesign nor layout changes for easier upgrade to next emission level. Thanks to optimized combustion, leadership on performance and fuel efficiency is confirmed, while the maintenance-free after-treatment system ensures low running costs avoiding unplanned downtime.
