Frequently Asked Questions – Industrial & Marine Silencers Ltd.
General & Company Information
An industrial silencer is a device designed to reduce noise produced by engines, machinery, or industrial processes while maintaining airflow and system efficiency. Industrial & Marine Silencers Ltd manufactures silencers tailored to frequency, flow, and pressure conditions for applications such as power generation, marine engines, and large industrial plants.
They provide engineered noise and emissions-control solutions, including:
- Exhaust gas silencers
- Steam vent silencers
- Air intake and extract attenuators
- Acoustic doors, canopies, and weather louvres
- Catalytic converters, SCR systems, and active DPF filters
- Turn-key project services: surveys, design, structural calculations, foundation drawings, installation, commissioning, and ongoing support
Their headquarters and manufacturing facility are in Shepshed, Leicestershire, UK (18‑20 Gelders Hall Road, LE12 9NH). They manufacture in-house, allowing full project management from design to commissioning.
They serve a variety of industries, including power generation, diesel/gas engine sets, marine and offshore, petrochemical, utilities, data centres, hospitals, and large industrial facilities worldwide.
You can contact them via phone or email with project details, including noise or emission problems, engine size, flow requirements, space constraints, and desired outcomes. They will arrange a survey or design discussion.
Acoustic Solutions / Noise Control
They provide tailored noise control solutions, including reactive and absorptive silencers, air intake and exhaust attenuators, acoustic canopies, doors, and louvres. These solutions reduce sound levels while maintaining airflow efficiency.
Industrial silencers reduce noise by absorbing, reflecting, or redirecting sound waves. Absorptive silencers use acoustic materials to absorb energy, while reactive silencers use chambers or baffles to cancel specific frequencies.
Yes. They offer retrofitting and upgrading of existing machinery, exhausts, and ventilation systems to meet modern noise regulations.
The selection process involves a site survey, identifying noise sources, assessing flow and pressure drop requirements, and considering space constraints. Industrial & Marine Silencers Ltd designs customised solutions to meet regulatory and operational needs.
Industries like power generation, marine, petrochemical, manufacturing, and hospitals benefit from noise reduction solutions to meet workplace safety and regulatory standards.
Reactive silencers: Use baffles and chambers to reflect and cancel sound at specific frequencies.
Absorptive silencers: Use acoustic lining to absorb sound energy across a wide frequency range.
Yes. They engineer silencers to withstand extreme temperatures, high flow rates, and pressure conditions commonly found in industrial and marine applications.
Installation times vary by project size and complexity. Turn-key services provided by Industrial & Marine Silencers Ltd ensure smooth project management, minimising downtime and disruption.
Steam vent silencers reduce noise from the release of high-pressure steam in industrial plants. Industrial & Marine Silencers Ltd designs these silencers to safely vent steam while significantly lowering sound levels, protecting personnel and meeting regulatory noise limits.
Emission Reduction Solutions
They provide catalytic converters, SCR systems, and patented active DPF filters to reduce harmful emissions such as NOx and particulate matter. Solutions are customised for industrial engines, marine engines, and power generation systems.
An SCR (Selective Catalytic Reduction) system is an emissions-control technology that reduces nitrogen oxide (NOx) emissions from industrial and marine engines. Industrial & Marine Silencers Ltd designs SCR systems that inject a urea-based solution into exhaust gases, converting NOx into harmless nitrogen and water, achieving reductions of over 90%.
Industrial & Marine Silencers Ltd is a leading supplier of SCR systems for industrial and marine applications worldwide. Their systems are engineered for high efficiency, compliance with global emissions standards, and minimal operational disruption.
A Diesel Particulate Filter (DPF) captures soot and particulate matter from diesel exhaust gases. Industrial & Marine Silencers Ltd’s active DPF filters self-regenerate, removing accumulated soot without complex fuel or electrical pre-heating, improving engine performance and reducing environmental impact.
Yes. Industrial & Marine Silencers Ltd provides bespoke retrofit solutions for SCR systems, DPF filters, and other emissions solutions to help clients meet current regulations without replacing the engine.
Selection depends on engine type, flow rate, regulatory requirements, and space constraints. Industrial & Marine Silencers Ltd performs surveys and system analysis to design tailored emission solutions.
Yes. Their solutions comply with global emission regulations, including IMO MARPOL for marine engines, EU Stage V, and other local industrial standards worldwide.
Industrial & Marine Silencers Ltd provides guidance on routine inspections, cleaning, and regeneration schedules. Their systems are designed for minimal maintenance while ensuring long-term compliance and efficiency.
The IMSeco “Airless” SCR System is an advanced emissions control solution from Industrial & Marine Silencers Ltd, designed for industrial and marine engines. Unlike traditional SCR systems, the “Airless” design eliminates the need for compressed air, using a patented injection method to evenly distribute the urea-based reductant into the exhaust stream. This ensures highly efficient nitrogen oxide (NOx) reduction (up to 98% NOx reduction ), lower operating costs, simplified maintenance, and reliable compliance with global emissions standards. It is suitable for both new builds and retrofit projects.
Project Services & Turn-Key Solutions
Turn-key services include site surveys, acoustic and emissions design, structural calculations, foundation drawings, in-house manufacturing, installation, commissioning, and ongoing maintenance support.
Turn-key solutions provide a single point of responsibility, reducing project risk, simplifying coordination, ensuring optimal performance, and meeting regulatory compliance.
Yes. They manage projects worldwide, including large power plants, marine engines, offshore facilities, and industrial plants, providing customised engineered solutions.
Quality is ensured through in-house manufacturing, skilled engineering teams, compliance with acoustic and structural calculations, and adherence to global regulatory standards.
They provide ongoing maintenance, inspection, troubleshooting, and retrofitting services to ensure long-term performance and regulatory compliance.
Industrial & Marine Silencers Ltd provides integrated solutions that combine acoustic silencers with emission reduction systems such as SCR and DPF filters. This holistic approach ensures machinery and engines meet strict noise and emissions regulations while maintaining operational efficiency.
