Proventia to develop and supply Stage V exhaust after treatment systems to Kohler

Proventia, a Finnish-based emission and testing technology company, is pleased to announce that the leading engine manufacturer Kohler has selected Proventia as a development partner and supplier for exhaust aftertreatment systems used in Kohler Stage V engines.

The collaboration includes the development and manufacturing of EU Stage V compliant exhaust systems for the new Kohler KDI3404 engines in the 105 kW power range. The Stage V emission standard comes into force in this engine category in January 2020, limiting not only the nitrogen oxides (NOX) and overall mass of particulate matter (PM) in the exhaust gas but also the number of particles (PN). Proventia develops, designs, tests and supplies complete Stage V compliant exhaust aftertreatment systems for Kohler engines. Systems include emission control technologies such as diesel oxidation catalyst (DOC), diesel particulate filter (DPF) and selective catalytic reduction (SCR) technologies, as well as thermal insulation components. The Kohler 105 kW engines are used, for instance, in agricultural and construction equipment, as well as industrial gensets, and the exhaust systems must meet the mechanical, operational and durability requirements of both mobile and stationary applications.

“The systems used by Kohler for aftertreatment operations represent the state-of-the-art in the technology currently available on the market. Thanks to the all-in-one configuration, manufacturers will be able to make best use of small footprints during the installation due to the very compact design of Kohler engines. In addition, the regeneration will be totally transparent to the end user, thus ensuring high levels of productivity and efficiency for the entire machine,” declares Massimiliano Bonanni, Kohler Director - Engineering.

“Kohler is a world-renowned manufacturer of engines, and we are pleased that they have chosen Proventia as their Stage V emission partner for 105 KW engines. We will do everything to ensure the project is a success and leads to new cooperation and business opportunities between Proventia and Kohler in the future,” says Jari Lotvonen, President & CEO, Proventia Group.

About the EU Stage V emission standard

Stage V is the world's toughest emission standard for non-road mobile machinery, including machines for construction, agriculture and materials handling. Stage V emission limits will come into force in 2019 and 2020. Stage V will bring much more stringent regulations for a wider scope of engines, smaller diesel engines included.
