Application areas

Features and Values

The DNX-Marine catalyst can be optimized to meet the various operating conditions on an engine by varying the active constituents of the catalyst.

The DNX-Marine catalyst for marine applications is extra reinforced to tolerate the many vibrations the catalyst is exposed to on a marine engine.

Our experience on engines as well as extensive testing on shakers in our laboratories have proven that the DNX-Marine catalyst maintains its high performance and trouble-free operation during a long period in a wide range of different operating conditions.
