The patented ultra-clean emissions control technology has been rigorously tested by independent labs and shown to consistently reduce the emission of criteria pollutants contributing to smog (CO and NOx) to near zero levels for natural gas engines.
Our emissions technology, developed with funding from the California Energy Commission and Southern California Gas Company, has been independently verified by New Jersey’s Department of Environmental Protection and by AVL California Technology Center. Emissions measurements from stationary systems equipped with the ultra-low emissions technology conform to the current California Air Resource Board (CARB) 2007 carbon monoxide (CO) and nitrogen oxide (NOx) standards for distributed power generation.
Our journey in the emissions after treatment business began in 2006 as a response to California’s South Coast Air Quality Management District’s (SCAQMD) implementing more aggressive emissions rules based on California Air Resources Board (CARB) standards.
