Donaldson Co., a manufacturer of filtration systems and parts, announced that the Houston Advanced Research Center has awarded the company a $750,000 grant for nonroad retrofit DPF/selective catalyst reduction (SCR) system development and verification. The award is in response to a grant application request from the Texas Environmental Research Consortium New Technology Research and Development.

“We are pleased to receive this grant, which is awarded based on the successful completion of project goals, including submission for verification of PM/NOx control to the Environmental Protection Agency by April 2011,” says Fred Schmidt, director of the Emissions Retrofit Business at Minneapolis-based Donaldson. “The DPF/SCR technology will permit fleets to reduce both PM and NOx emissions on certain offroad equipment.”

Schmidt says the technology is targeting PM reductions of 85-plus percent and NOx reductions of more than 70 percent. “What distinguishes the Donaldson approach relates to the diesel exhaust fluid (DEF) injection preparation and mixing method,” he says. “Our system will optimize mixing, thus providing significant performance improvements, DEF deposit prevention and reduced ammonia slip compared to current industry-standard approaches.”
