Retrofitting SCR: Why Experience Matters
Retrofitting Selective Catalytic Reduction (SCR) exhaust aftertreatment onto existing generator installations is rarely straightforward. Every project presents its own engineering challenges, from limited installation space to engine operating conditions that can affect system performance. The challenges of SCR retrofits Limited installation space Generator rooms and plant areas are often already congested, leaving very little room to accommodate additional exhaust treatment equipment. Engine backpressure limits Adding reactors, silencers and pipework can increase exhaust backpressure beyond the engine manufacturer's limits, potentially affecting engine performance and reliability. Temperature and dosing control Maintaining catalyst operating temperatures during low-load operation and accurately controlling AdBlue® dosing are essential to achieving high NOx reduction while preventing deposit formation. Why customers choose Agriemach Successful SCR retrofits require more than quality components - they demand careful mechanical and thermal engineering. • Bespoke system design – Our NOxMASTER™ SCR systems are engineered to suit each application, taking account of exhaust mass flow, operating temperatures and engine-out emissions. • Compact integrated solutions – By combining silencing, the mixing duct and SCR reactor into a single engineered assembly, we minimise installation footprint while remaining within engine backpressure limits. • Complete project delivery – Since 1976, we've supported customers across the UK and Ireland with design, installation, commissioning and ongoing service, helping keep projects on schedule and performing reliably. Whether you're upgrading an existing generator to meet tighter emissions requirements or planning a new compliance strategy, our engineering team can help. We've successfully delivered SCR retrofit solutions for a wide range of challenging installations and would be happy to discuss your application. Engineered solutions – it's what we do.

Its not all SCR in the World of Emissions | DOC/DPF
It's not all about SCR in the world of emissions... although you could be forgiven for thinking so with all the updates! Let's not forget these smaller Diesel Oxidation Catalysts (DOCs), quietly doing their job day in, day out. Working out of sight, they're helping reduce harmful emissions in environments where people live and work - often without anyone even realising they're there.
