For potential customers, selective catalytic reduction offers obvious advantages. First, SCR technology significantly reduces NOx emissions by up to 90%, making it possible for vehicles and machinery to comply with increasingly strict emissions standards. Second, it increases fuel efficiency because the engine is optimized for power while keeping emissions at the same low level. Thirdly, SCR systems demand very little attention and can last for many years. Over time this saves on maintenance costs, which translates into reducing operating expense for each vehicle in any equipped fleet; Lastly, by using SCR an enterprise can raise its reputation. It demonstrates that the company is committed to environmental stewardship.These benefits add up: lower operating costs, compliance with regulations, and a better public image.
