Radnor, Penn.-Airgas Inc. reports that its AiRx?äó Diesel Exhaust Fluid (DEF) has been certified by the American Petroleum Institute. DEF is used in Selective Catalytic Reduction (SCR) technology to reduce diesel exhaust pollutants. API certification verifies that manufacturers and distributors are operating in compliance with industry standards and that DEF meets quality standards. Airgas, the largest U.S. distributor of industrial, medical, and specialty gases, and welding, safety, and related products, markets Airgas AiRx DEF through Airgas Specialty Products. “In order to meet 2010 clean air regulations, most diesel truck manufacturers are using SCR technology in all new models,” said Ted Schulte, Airgas Specialty Products president. “With this technology, DEF is injected into the exhaust stream to break down harmful nitrogen oxides, NOx, into inert nitrogen and water.” Airgas has been providing pollution control solutions for air quality since the early 1980’s. “Our nitrogen oxide abatement, or DeNOx, experience with stationary applications, such as coal- and natural gas-fired power plants, served us very well in creating Airgas AiRx to work with diesel engine SCR technology in mobile applications,” said Schulte. Available in a variety of package sizes ranging from one-gallon containers to bulk trailers, Airgas AiRx is supplied to truck stops, fuel retailers, private fleets, and lubricant and fuel distributors nationwide. With more than 5,000 vehicles, Airgas maintains one of the largest private truck fleets in the country and will be using Airgas AiRx Diesel Exhaust Fluid in all of its new trucks that use SCR technology. Other major DEF providers in the U.S. include Terra Industries Inc. (GM Sept. 21, p. 1) and Yara North America (GM Sept. 28, p. 1).
