Particulate­ filters and SCR systems for ships

Practice-proven after-treatment of exhaust gases by TEHAG

TEHAG / Particulate filters and scr systems for ships - Reference 1

Thanks to our innovative products, we can offer efficient solutions for exhaust treatment for ship propulsion engines as well as an­cil­lary components, as long as they meet the few conditions that exist for problem-free operation. In particular, the use of low-sulphur fuels is extremely important in order to ensure that ex­haust treat­­ment systems work pro­perly over the long term.


Depending on your application, we can of­fer you particulate filter sys­tems as well as our T-blue NOx Reduction System for fuels with sulphur content of up to 1,000 ppm.

Barges, passenger ships, police and coast guard ships, yachts and coasters are al­ready operated with suitable fuels to­day or can quick­ly and easily be switch­ed ov­er to the necessary fuel qualities.

In the past, this has allowed us to suc­cess­fully complete a variety of pro­jects with shipyards and shipping com­pa­nies.

Our T-blue NOx Reduction System is par­ti­cu­larly well-suited to use with na­tu­ral gas engines and can sustainably reduce nitrogen oxide emissions in these applications.

Furthermore, special slip catalysts can be used to prevent un­wan­ted gas slip.

Naturally, all exhaust treatment systems that are designed and ma­nu­factured by TEHAG comply with stringent approval criteria.

This means, for example, that all of our particulate filter systems are tested in ac­cor­dance with the specifications laid out by the VERT® Association, comply with the Swiss LRV directive, and have, in part, received general operating permits from the German Fe­de­ral Motor Transport Authority.
