The U.S. Environmental Protection Agency (EPA) has placed Nett Technologies Inc.’s BlueMAX™ 200 urea-based selective catalytic reduction (SCR) system on the National Clean Diesel Campaign’s Emerging Technologies List. The system is approved for use on a project funded through the Emerging Technologies grant program for on-highway, 4-stroke, non-EGR, heavy heavy-duty diesel engines originally manufactured from 1994 through 2006 and not originally equipped with a catalyst.

Nett’s BlueMAX™ 200 SCR system is designed to effectively control nitrogen oxides (NOx) emissions from heavy-duty diesel engines. The system uses a urea control strategy that relies on a NOx concentration measurement by a sensor positioned upstream of the SCR catalyst. Based on the NOx sensor signal, in combination with an engine mass air flow sensor and temperature sensor, the necessary urea dosing rate is calculated by the control algorithm. The NOx sensor-based control strategy makes the system very suitable for retrofit applications. No time-consuming calibration (such as through engine mapping) is necessary, and the system can be installed on a wide range of diesel engines, including mechanical engines. The Nett BlueMAX™ 200 SCR system also controls diesel particulate matter (DPM), hydrocarbons (HC) and carbon monoxide (CO).

Nett is known for its ability to provide direct-fit solutions through an integrated approach of application engineering and manufacturing. The Nett BlueMAX™ 200 SCR system is offered as a direct-fit design; this simplifies the installation and offers a customized cost-effective solution to a sophisticated emission control problem.

Information on the EPA’s Clean Diesel Emerging Technologies Program

The Clean Diesel Emerging Technologies Program is an opportunity to advance new technologies to reduce diesel emissions from the existing fleet. Funding under this program is now available for the second year of emerging technologies. Eligible entities include: U.S. regional, State, local, tribal or port agencies or non profit groups related to transportation or air quality. School districts, federally recognized Indian tribes, municipalities, metropolitan planning organizations (MPOs), cities and counties are all eligible entities under this program.

The use of retrofit technologies is 100% funded under this program. The National Emerging Technology RFA closes on May 5, 2009. For more information visit: http://www.epa.gov/otaq/diesel/prgemerg.htm
