The global industrial noise-control sector is undergoing strong and sustained growth, especially in emerging economies such as India. As the nation strives to become industrially advanced, with refineries, petrochemical complexes, power plants, steel units, and process industries growing aggressively, noise control is becoming a mission critical requirement. Tightening regulatory norms, combined with the emergence of large-scale, high-energy infrastructure projects, is expected to amplify demand for advanced acoustic engineering solutions.
Facilitating plant safety, environmental compliance, equipment reliability, and workforce well-being, silencers have become indispensable components that demand advanced engineering and fabrication capabilities. This is where Indira Industries, India’s premier partner in noise control acoustic engineering, and cutting-edge fabrication, excels.
Today’s discerning clients prefer predictable attenuation, lower allowable back pressures, long service life, and proven engineering capability. Yet, several manufacturers fall short of achieving guaranteed noise-level compliance, particularly within constrained plant layouts. Managing back-pressure limitations while meeting compliance expectations - especially noise reduction in dusty environments - remains a critical challenge. With over four decades of experience, Indira Industries expertly addresses these complexities, serving EPCs, OEMs, and global process industries as a leading partner.
Expertise Refined Over Decades
Established in 1987, Indira Industries has committed itself to achieving the highest standards of quality excellence and engineering specialization. This commitment has enabled the firm to become the chosen partner for clients across industries worldwide. A reliable Indian manufacturer delivering uniquely designed, world-class solutions globally, Indira Industries leads the noise-control sector with products that perform consistently.
Across dusty environments such as cement, mining, steel, and more, the company supplies tailored dust-media and heavy-particulate acoustic solutions. It leverages a combination of detailed acoustic calculations backed by empirical field data, engineering modeling software, deep knowledge of steam dynamics, gas relief systems, and high energy flow aerodynamics, along with transparent technical collaboration. The result is a range of advanced silencers that outperform conventional solutions, delivering consistent value, operational reliability, and regulatory compliance.
“Our strength comes from decades of engineering experience, deep technical partnerships with global leaders, and a highly committed team. Supported by world-class machinery and in-house material testing facilities across our manufacturing campus, we are able to offer our clients a dependable, end-to-end solution”, states Manikandan Ponnuswamy, Managing Partner, Indira Industries. Indira Industries’.
portfolio features cutting-edge industrial noise-control systems and solutions, industrial flow-regulation and control systems, and stainless-steel railway coaches and components fabrication solutions. These services and products have been perfected over the decades, consistently aligned with evolving client requirements. The company has a thriving, supportive industrial ecosystem developed with nearby suppliers and partners, which enables sustained excellence.
Moreover, the company’s extensive certifications, including ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, EN ISO 3834-2, EN 15085-2, IRIS ISO/TS 22163:2017, and EN 1090-2 (CE), demonstrate its credibility. Leadership at Indira Industries does not stop at engineering alone. The company adheres to global standards for quality, environmental management, occupational health and safety, welding quality requirements, railway vehicle welding, CE-compliant structural execution, and railway QMS. Further approvals from EIL, Avant-Garde, and Toyo Engineering reinforce the company’s commitment to excellence across business aspects.
A Team That Stands Out
Behind Indira’s success is a team of carefully chosen, highly qualified, and extensively trained professionals. Its workforce of over 650 professionals comprises 120 specialists in the silencer division alone. These personnel include acoustic and mechanical designers, project managers, certified welders and NDT technicians, skilled fabricators, and QC and documentation experts. The combined expertise of these professionals, coupled with Indira’s strong commitment to client satisfaction, makes the experience seamless.
Indira Industries’ journey has evolved from a modest unit into a comprehensive engineering operation with diversified capabilities
The teams brainstorm solutions, rigorously pre-planning every solution and execution strategy. With a clear project-ownership culture that values accountability and transparency, the company facilitates a streamlined workflow. Harmonized operations between engineering, production, QC, and logistics departments, along with structured multi-stage inspection and documentation processes, enhance the overall execution experience. These practices minimize rework, facilitate trouble-free installation, and build long-term client trust.
Indira’s R&D division plays a critical role in defining solution performance. Committed to continuous improvement, the company has nurtured a robust R&D department that focuses on innovation. The team works continuously to enhance internal baffle geometries, flow-path aerodynamics, acoustic packing configurations, structural integrity for extreme temperature and pressure conditions, and modular silencer designs.
Research-led engineering is a key differentiator for us. Through our German collaborations, we gain access to anechoic and reverberation chambers, advanced acoustic simulation software, and laboratory-grade testing facilities. This enables us to scientifically validate designs and continuously improve attenuation performance,” adds Manikandan Ponnuswamy.
Journey and Future Roadmap
Indira Industries’ journey has evolved from a modest unit into a comprehensive engineering operation with diversified capabilities. The company operates across four world-class manufacturing facilities in Ranipet with 845,000+ sq.m of integrated operational space, and a fabrication capacity exceeding 700 tons per month. Enhanced by German technology collaborations, Indira has established a global footprint across the USA, the UK, Argentina, Indonesia, the Middle East, and Southeast Asia. Its achievement of exporting to China stands out as a unique milestone in the sector.
“We have supplied to leading refineries, power stations, EPCs, OEMs, and jet engine test facilities, demonstrating our engineering depth and manufacturing strength. Looking ahead, our focus is on delivering next generation acoustic solutions that are robust, compliant, and engineered for global industrial, mobility, and energy applications,” adds Manikandan Ponnuswamy.
Committed to this roadmap, the company is focusing on emerging trends such as nitrogen vent silencers used in inerting, blanketing, purging, and PSV systems. Specialty gas silencers, expanded automation in manufacturing and inspection, large-scale modular production for export, and advanced CFD and acoustic simulation tools are key areas of focus.
The company is also evaluating opportunities in compact gas turbine systems that generate high acoustic energy within small footprints—driving demand for high-attenuation silencers, acoustic enclosures, and advanced flow-control solutions. Emerging opportunities in edge computing hubs, microgrids, and industrial clusters are also under consideration. Beyond this, Indira Industries is exploring strategic expansion into automotive acoustic solutions, road and traffic noise abatement, room acoustics, and passenger comfort systems for bus and rail sectors. With these initiatives, Indira Industries aims to further strengthen its leadership position in the industrial noise-control domain.
