Whenever internal combustion engines are used to generate power, emissions are also created. We have made it our goal to sustainably and effectively reduce these unwanted pollutants in compliance with emissions laws, which are becoming increasingly strict around the world.
With more than 30 years of experience, we are a competent and reliable partner for after-treatment of exhaust gases from internal combustion engines. With our innovative products, we offer solutions for efficient reduction of noise pollution and toxic emissions from petrol, natural gas and diesel engines.
We offer comprehensive expertise and a wide range of products for nearly every application – from mini-excavators to ship propulsion, from power generators to locomotives – both for original equipment and new construction projects as well as for retrofitting of existing vehicles and machinery. With our comprehensive, in-house engineering expertise, we are happy to help you develop the exhaust systems and drive concepts of the future. All products in our portfolio can be used as original equipment as well as to retrofit diesel, petrol and natural gas engines.
