Oxidation catalyst systems

Our 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.
