Innovation
Why SCR Technology?
Selective Catalytic Reduction (SCR) systems are not a new concept in the industry. The emissions regulation option first appeared in the on-highway space in 2007 and has continued to make its way into industrial spaces such as marine, mining, and rail markets. In the Oil & Gas industry, Cummins has made the switch to supporting EPA Tier 4 emissions standards by implementing robust SCR systems which result in critical emissions and fuel economy improvements for our customers. The decision to utilize proven SCR systems was influenced by its anticipated longevity in the industry and positive impact on customer performance. SCR systems deliver the reliability and operational efficiency that you have come to expect from Cummins solutions.
