DeNOx SCR

Ecospray offers a wide range of DeNOx systems for marine applications to remove Nitrogen Oxides from diesel engine exhaust gas, using SCR (Selective Catalytic Reduction) technology, up to 25 MW engine output.

Designed for both new builds and retrofits, the system is compatible with MDO/MGO/VLSFO fuels and SOx scrubber setups, including boilers and silencers.
It features Ecospray’s patented high-efficiency spraying lances and nozzles, delivering excellent performance with low back pressure (<20 mbar) and minimal ammonia slip.
A flexible concept to suit all installation requirements, Ecospray SCR is available in square and round design with catalytic elements of different substrate, coating and cell-density, configurable in size and layers to achieve the required efficiency vs. backpressure targets.
Advanced automation options support multiple interfaces (ModBus, ProFiBus, RS432), backed by comprehensive global service for performance, lifecycle, and spare parts support.
