Eco-Friendly System

HSD Engine has applied proprietary technology to develop the DelNOx system for exhaust after-treatment. This highly efficient system operates at low temperature and enables customers to satisfy marine and industrial regulations on nitrogen oxide (NOx) emissions.

DelNOx® SCR System

DelNOx is a NOx reduction system developed by the unique technology of HSD engine and it is an eco-friendly equipment that can meet nitrogen oxide emission regulations required in shipbuilding and various industries.

DelNOx is the world’s first SCR system installed at the after of turbocharger and applied low temperature catalyst as a new concept.
Based on excellent performance and technology, it is being produced in earnest from 2016 when IMO Tier III regulation came into effect.

Principle of SCR (Selective Catalytic Reduction)

  • SCR (Selective Catalytic Reduction) : Selective Catalytic Reduction (SCR) System
  • The SCR system is an eco-friendly method for NOx reduction. Chemical reactions using a reductant in the catalyst layer convert nitrogen oxides in the exhaust gases into harmless pure water and nitrogen.
