Our expertise is built on decades of engineering precision and a deep understanding of sound and emissions performance.
Designing for performance
Collaborative from the Start
Our process begins with partnership. We work closely with customers to define space constraints, performance goals, and regulatory requirements for their exhaust silencer or aftertreatment system — then explore multiple design pathways to achieve the most efficient and reliable solution. From concept through production, we balance performance, weight, and manufacturability to ensure the final custom exhaust silencer design meets every expectation.
Design for Manufacture
Manufacturability is built into every phase of our industrial silencer design process. Using early-stage optimization, material selection — including aluminized steel and stainless steel — and tooling feasibility assessments, we identify the most effective way to bring each concept to life, minimizing cost and maximizing efficiency.
Integrated Expertise
Our design teams bring together specialists in emissions control, thermal management, acoustic engineering, NVH, and structural engineering to develop fully integrated exhaust and aftertreatment systems. This cross-functional approach allows us to optimize performance, simplify installation, and ensure seamless integration within generator, compressor, turbine, and stationary engine architectures.
Investing in What’s Next
Across our global operations, we continually invest in advanced manufacturing technologies that strengthen the performance of our industrial exhaust silencers and aftertreatment systems at every stage of production. At our facility in Arcadia, WI, high-performance laser cutting enables us to process a wide range of materials — including stainless steel and aluminized steel — with exceptional speed and precision, producing cleaner cuts that minimize secondary finishing. The result is improved efficiency, greater consistency, and enhanced part quality across our full line of custom silencers and emissions suppression systems.
Engineered for Efficiency
Our teams draw on decades of experience in aftertreatment systems, industrial exhaust silencer design, and accessory engineering, continuously refining form and function to meet evolving global emissions and noise regulations. By embedding cost-efficiency and quality assurance into every decision, we deliver sound attenuation and emissions suppression products that are high-performing, durable, and practical to maintain.
Testing & Validation
At GT Silex, performance isn't assumed — it's proven. Our comprehensive testing and validation capabilities ensure that every industrial exhaust silencer, acoustic system, and aftertreatment product we design performs reliably under real-world conditions, meeting the highest standards for quality, durability, and emissions and noise compliance.
Analysis-Led Validation
Before any exhaust silencer or aftertreatment system reaches the test bench, our engineers use advanced Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD) to predict structural, thermal, and acoustic behavior. These digital simulations allow us to refine custom silencer designs early in development — reducing iterations, improving accuracy, and optimizing sound attenuation performance from the start.
In-House Testing Capabilities
Our dedicated exhaust silencer testing facilities in the United States and India validate design performance through rigorous lab and field evaluations. Using industry-standard methods and proprietary tools, we replicate real-world industrial power application conditions to ensure each silencer and aftertreatment system performs as intended in the field.
Thermal & Environmental Testing
We evaluate thermal behavior and long-term durability through hot blower testing, thermal imaging, and temperature drop analysis. Corrosion and environmental exposure are verified through humidity and salt fog testing to ensure sustained reliability.
Performance & Compliance Validation
Each industrial exhaust silencer and emissions suppression system is validated against customer and regulatory requirements through pressure drop and backpressure testing, spark arrestor verification, and full data acquisition and traceability. Documented best practices and Nelson Global's Engineering Standard Work Processes ensure consistency across every custom exhaust silencer project.
Acoustic & Vibration Testing
Our acoustic testing labs feature advanced equipment for transmission loss measurement, sound source localization, and modal analysis to verify sound attenuation performance. For vibration durability testing of industrial silencers and exhaust systems, we use 3DOF and 6DOF electromechanical shakers — including a specialized six-axis system for bellows testing — to simulate high-cycle fatigue, displacement, and torsional loads.
An Unrelenting Commitment to Quality
Quality is at the core of everything we do. Our ISO-certified facilities, AWS-certified welders, and rigorous inspection processes ensure every component meets the highest standards. From precision assemblies to complex structural solutions, GT Silex delivers durable, reliable products you can trust.
