Proventia, Kohler team up on Stage 5 engines

The collaboration includes the development and manufacturing of EU Stage 5 exhaust systems for the new Kohler KDI3404 engines in the 105 kW (140 hp) power range. The Stage 5 emissions standard comes into force in this engine category in January 2020 and places new limits on NOx and overall mass of particulate matter (PM), as well as particle number (PN)

“Kohler is a world-renowned manufacturer of engines, and we are pleased that they have chosen Proventia as their Stage 5 emission partner for 105 KW engines,” said Jari Lotvonen, President & CEO, Proventia Group. “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.”

Proventia will develop, design, test and supply complete Stage 5 exhaust aftertreatment systems for Kohler engines, which will include diesel oxidation catalysts (DOC), diesel particulate filters (DPF) and selective catalytic reduction (SCR) technologies, as well as thermal insulation components. The 105 kW Kohler engines are used in agricultural and construction equipment, as well as industrial generator sets.

“The systems used by Kohler for aftertreatment operations represent the state-of-the-art in the technology currently available on the market,” said Massimiliano Bonanni, Kohler’s director – Engineering. “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.”

Proventia’s technology is on display at Bauma 2019 in Hall A4, Stand 211.
