A History of Successful Development


Clients All Over the World
The company was established in 1981 and over the years our operations have focused on systems to enhance emission control and performance. STT Emtec´s customers and clients can now be found in Europe, Asia, Australia, as well as, South and North America.


Successful Development Projects
STT Emtec´s history goes far back and includes a number of products developed in-house by its Research & Development Department. Much of the work is being conducted in the company´s own modern engine testing laboratories. Engine and

system analyses alike, performed with the modern analyzing tools, allowed for

substantial reduction of emissions and noticeable performance enhancement in diesel and gasoline engines.


DNOx® - Emission Control System For OEM and Retrofit Markets
Since late 1990s the Emission Systems team has been developing DNOx® emissions control system. This system allows for significant reduction of all legislated diesel exhaust emissions. A considerable advantage of the system is its applicability for OEM installation on new production engines, as well as retrofits to existing engines in service.
