STT Emtec specialises in products to reduce emissions from diesel engines, with a focus on nitrogen oxides (NOx) and particulate (PM) emissions. Using STT Emtec technology, existing diesel engines can be adapted to current and proposed future emission legislation.
The STT Emtec DEF Dosing System is a model based system for high accuracy dosing used in SCR systems. It consists of ECU, DEF Supply Pump, DEF Dosing Unit and Injection Nozzle. The system has been developed in house by STT Emtec after many years of experience in the field of exhaust aftertreatment.
The system is air assisted to achieve a superior atomization and spray quality and also allows for the system to be flushed clean upon shut down to avoid problematic DEF deposits. Both 32.5% and 40% DEF can be used and the system is available in several dosing ranges.
HC Dosing systems for active DPF regeneration are also available.
This system reduces NOx through selective catalysis with urea as the reduction agent. Compressed air is used to achieve a high degree of urea atomization in the exhaust. This, together with the flow optimized mixer minimizes risk of clogging and guaranties the high level of performance and trouble free operation.
STT Emtec also offers services in our state of the art engine test laboratory. The testing department has extensive laboratory resources including three engine test cells with emission measuring equipment and capability of testing everything from heavy duty diesel engines to small gasoline engines. The engine laboratory is accredited according to ISO/IEC 17025 for EU and US legislative emission tests.
The history of STT Emtec, headquartered in Sundsvall, Sweden, goes back to 1981. Originally involved in land based diesel engine technologies, the vision has always been to establish the company as one of the world leading technology providers in the field of emissions and engine performance systems, many of which have been developed in house. As well as providing after-market systems STT Emtec is a key component supplier to the world’s automotive, marine and industrial engine manufacturers. The move into emission control systems for the maritime sector is a natural progression from the automotive experience. It is obvious that the technologies from STT Emtec will contribute considerably to the shipping industry’s emission reduction efforts.
