Oxidation catalyst systems
Johnson Matthey's Modulex™ and DualOx® catalytic converters for stationary engines - reliable engine exhaust emission control combined with silencing technology.
Modulex and DualOx catalytic converters are designed to accommodate oxidation and three-way catalyst elements to reduce emissions and noise. This technology operates over a wide range of conditions including rich-burn, lean-burn and diesel engine applications, in market segments such as:
-
Gas compression
-
Gas transmission
-
Power generation
-
Irrigation and pumping
-
Standby equipment.
Our highly reliable HAPGuard Monitor helps engine operators comply with RICE NESHAP requirements.
