Proven Technologies for Emission Control

DEC Marine develops and supplies a range of technologies that support emission reduction, regulatory compliance, and long-term operational performance. From complete SCR systems to catalysts, monitoring equipment, and exhaust components, every product is engineered for demanding operating environments and integrated system performance.

Designed Around Compliance. Built to
Work Together

Effective emission control is achieved through the interaction of multiple technologies. Catalysts, control systems, monitoring equipment, silencers, and exhaust components each play an important role in overall system performance. Together, they form integrated solutions designed to reduce emissions, support compliance, and perform reliably over time

Effective Particulate Matter Reduction

DPF Systems

DPF (Diesel Particulate Filter) Systems are designed to reduce particulate emissions and support operators facing increasingly demanding environmental requirements.
The systems can be integrated into broader emission control strategies and adapted to a wide range of operating profiles and applications.


Key Benefits

  • Reduced particulate emissions
  • Improved environmental performance
  • Integration with broader emission control strategies
  • Suitable for both new and existing installations

Optimised Catalytic Performance

SCR & OXI Catalysts

Catalysts are critical to overall emission reduction efficiency. DEC Marine supplies SCR catalysts for NOx reduction as well as oxidation catalysts that support the reduction of carbon monoxide (CO) and volatile organic compounds (VOC). Selected for long service life and reliable performance, the catalysts are designed to meet the specific requirements of each application.


Key Benefits

  • High conversion efficiency
  • Long operational lifespan
  • Designed for demanding operating environments
  • Supports NOx, CO, and VOC reduction

Precision Monitoring and Control

NO Analyzer Units

NO Analyzer Units provide continuous emissions monitoring that supports system optimisation, performance verification, and compliance documentation. For applications requiring advanced control strategies, analyser feedback can also be used to optimise dosing and overall SCR performance.


Key Benefits

  • Continuous NOx measurement
  • Enhanced system optimisation
  • Improved compliance verification
  • Supports automated control strategies
  • Valuable operational insight

Noise Reduction Without Compromise

Exhaust Silencers

DEC Marine exhaust silencers, including spark arrestors, are designed to reduce noise levels while maintaining efficient exhaust flow and overall system performance. Solutions can be integrated into larger emission control systems or supplied as standalone components depending on project requirements.


Key Benefits

  • Reduced exhaust noise
  • Efficient exhaust flow
  • Integrated or standalone configurations
  • Adapted to application-specific requirements
