Combustion Components Associates (CCA), a Connecticut-based company that manufactures air pollution control technologies, has received contracts for 18 of its ELIM-NOx SCR systems.

The orders include six diesel trucks in the New York metropolitan area and 12 off-road construction trucks in Southern California.
The orders, which exceed $400,000, represent the first large commercial contract for ELIM-NOx since it was commercialized for retrofit on existing on-road and off-road diesel applications and new trucks earlier this year.
CCA's ELIM-NOx SCR technology is designed to achieve 90% NOx reduction while overcoming any fuel economy penalties. Additionally, vehicles do not need to use ultra low-sulfur diesel fuel oil with this technology.
R. Gifford Broderick, president of CCA, said, "The new orders confirm the commercial viability of the ELIM-NOx system on both on-road and off-road diesel trucks as a low-cost, high-efficiency technology. Our low-NOx technology is designed to help bring diesel truck engines into compliance with new EPA regulations, which require a 50% to 90% reduction in NOx, phased-in between 2007 and 2010."
With more than 600,000 new diesel trucks produced annually and 4 million existing trucks operating in various ozone non-attainment regions, the company says ELIM-NOx technology represents a huge low-cost incentive for diesel OEMs and fleet-owners for emission compliance.
The ELIM-NOx system works on the principle of Selective Catalytic Reduction using urea -- a safe and non-hazardous reagent. In addition to its cost-effectiveness, performance efficiencies, fuel economy and simplified controls, a unique feature of the technology is the proprietary "self-learn" monitoring system. This self-learn system uses sensors to measure NOx, exhaust temperature and record various engine parameters. It is temporarily mounted on the diesel truck for recording data as the vehicle operates in its normal driving conditions. The function is ideal for fleets that have identical vehicles, since the data from one vehicle can be utilized across the fleet resulting in high operating efficiencies.
Leveraging years of field expertise with power boilers and stationary engines, CCA has developed variants of its ELIM-NOx SCR technology control process with improved injector design and has filed two patents. These patent-pending technologies are designed to extend product durability, improve urea utilization and facilitate greater NOx reductions from diesel trucks.
