Tenneco Inc. announced that it has signed an agreement to acquire the mobile emissions business of Combustion Components Associates, Inc., a manufacturer of air pollution control technologies. The acquisition enhances Tenneco’s complete system integration capabilities for selective catalyst reduction (SCR) emissions control technologies designed to meet future more stringent diesel emissions regulations for passenger cars and trucks. CCA develops emissions control solutions for customers in the transportation and power generation industries. The company has designed and manufactured a Nitrogen Oxides (NOx) emission reduction system which is designed to reduce NOx emissions by 70 to 90 percent. This is accomplished by removing NOx through a chemical reaction and is considered the leading technology for helping diesel engines meet the NOx emissions standards. Customer demands for this new technology, driven by regulations, will increase in the U.S., Europe and China starting in 2010 – 2012. “This acquisition strengthens our advanced technology offering. “Combined with the SCR technology we produce today, Tenneco can offer our customers a fully-integrated emission control system to meet stringent diesel emissions regulations for NOx reduction,” said Gregg Sherrill, Tenneco Chairman and CEO. In addition to providing this innovative solution to original equipment manufacturers, Tenneco will also sell retrofit versions of the system for commercial vehicles. Later this year, the company expects to complete final validation testing for the system to be added to the EPA list of verified retrofit technologies. Tenneco will purchase CCA’s mobile emission business for approximately $16 million. The transaction is subject to customary closing conditions, including receipt of various third party approvals. Tenneco expects the transaction to close in September.
