Xeamos has developed an airless SCR solution for superyachts between 30 and 50 metres. The new system has been developed in response to requests from yards matching engine rooms on existing designs with the requirement to fit IMO Tier III-compliant SCR systems.
The system has been developed to dispense with the need for large and heavy air compressors.
Xeamos SCR systems are designed to ensure that diesel engines on yachts comply with the IMO Tier III NOx emission standard or above.
The latest design supports new builds applying airless SCR for engines in the range from 700 to 2000kW.
“The fact that yards will no longer have to install compressors offers major savings in terms of both weight and space,” explained a spokesperson from Xeamos. “The compact Xeamos solution can be designed with integrated sound attenuation that is tuned to the engine model.
Custom design
“Covering any geometry allowed by the laws of physics, this custom approach to design also includes in and outlet positions and the reactor housing.”
Xeamos zero-NOx solutions can be applied to both wet and dry exhaust systems and are MARPOL NTC 2008, IMO III certified.
Other certifications are possible depending on engine type.
The new system is Xeamos’ next generation v3 controller platform. Other key features of the zero-NOx SCR system include airless urea dosing up to 25 l/h, a 24 VDC power supply, CFD and FEM-aided design and Lloyds Register SSC approval.
The system is suitable for sulphur-containing fuels, and can handle exhaust gas temperatures of up to 600°C.
The new solution is being launched at METSTRADE 2024.
