Nox takeover

Emitec, a joint venture for emissions technology between the international automotive suppliers Continental and GKN Driveline, has acquired Danish company Grundfos NoNOx, one of the world's leading producers of pumps and related metering equipment for SCR systems.

"SCR is the most promising method for reducing the amount of nitrogen-oxides in exhaust emissions in order to comply with legislation while still improving engine economy," said Peter Gutzmer, head of the engine systems business unit at Continental Powertrain Division. "A metering system is the central component of this new SCR after-treatment technology and crucial for realizing further reductions in fuel consumption. The acquisition of Grundfos NoNOx by Emitec will complement the other SCR components already available at Continental and underline our leading position as a provider of complete systems."

"By acquiring Grundfos NoNOx, Emitec has the opportunity already at this initial stage to adopt an outstanding position in the global market," added Wolfgang Maus, chairman of the executive board of Emitec. "Above all, the combined access to the customer base of NoNOx affords a clear time advantage and synergies."

CEO and group president of the Grundfos Group, Carsten Bjerg, commented: “We are proud to hand over our innovative company to the automotive industry. This technology will now have even better development opportunities and can make a huge impact for the environment. We are convinced that Emitec will use its full potential.”

According to the deal, Emitec will acquire Grundfos NoNOx – with its development and production facilities in France – from Danish based Grundfos, a global manufacturer of industrial pumps. The company employs around 80 people. Grundfos NoNOx is one of the three major developers and producers of metering systems for SCR exhaust gas after-treatment systems. The metering systems inject a urea solution into the exhaust gas flow from a separate tank. The ammonia produced from the urea solution by hydrolysis reacts with the NOx in the exhaust gas and breaks it down by more than 80%. The SCR system not only reduces the harmful substances in the exhaust gas to a considerable extent, but also significantly lowers fuel consumption. SCR is the ideal solution for meeting the stricter EURO 5 exhaust gas standard – and the only one that meets EURO 6 - while at the same time reducing CO2 emissions.

The Grundfos Group began its activities in the field of NoNOx in 2002, and has since placed products for the two most sustainable solutions on the market, namely urea injection systems with and without air support. Target markets include, in particular, diesel engines for the truck and bus segments, as well as construction and agricultural machinery. Grundfos NoNOx already has notable manufacturers of commercial vehicles and exhaust gas systems among its clients. As the automotive sector is not one of the strategic core areas of the Grundfos Group, Emitec has now agreed to take over responsibility for these activities.

Emitec, a 50% subsidiary of Continental and GKN Driveline, is a specialist and innovative leader in the field of metallic catalyst supports and sooty particle filters for exhaust gas after-treatment systems. The production range opens up considerable synergy potential with the introduction of SCR systems in the truck and off-road market segment. Metallic support high-performance catalytic converters have low pressure loss and allow full engine power combined with minimal consumption. Flexible designs and structures ensure maximum effectiveness in a small fitting space courtesy of accurately coordinated turbulence. The SCR catalytic converter can therefore be fitted close to the engine to great beneficial effect.
