Steam Blow-off Silencer
Reduces steam and gas discharge sound by up to 60 dB(A)
Custom-engineered for high-pressure and high-temperature applications
Suitable for power plants, process industries, and energy systems
Steam or gas discharge can generate extremely high noise levels. The Steam Blow-off Silencer reduces this noise through a combination of reactive and absorptive elements, achieving noise reduction of up to 60 dB(A). Each silencer is custom-designed based on specific flow rate, pressure and temperature conditions, ensuring safe operation and reliable performance. It is suitable for power plants, chemical facilities and industrial process plants, and can be used in both new build and retrofit projects. The robust construction and high-quality materials ensure long-term reliability under demanding operating conditions.
The casing is manufactured from carbon steel or stainless steel with welded seams, designed to withstand high pressure and temperature. Internally, high-temperature resistant, impregnated mineral wool and perforated metal provide durable sound attenuation and broad-frequency absorption. The design accounts for gas expansion, flow velocity and allowable pressure drop, ensuring an optimal balance between acoustic performance and process requirements.
The steam blow-off silencer is ideal for steam and gas discharge applications in power plants, chemical and petrochemical facilities, and industrial process systems. It is installed on ventilation, safety and blow-off valve outlets, where it effectively reduces discharge noise to acceptable levels. The custom-engineered design allows straightforward integration into existing systems or new build projects, supporting both acoustic performance and operational safety.

Answers to common questions
Yes. All Merford silencers are custom-designed and can be used in both new construction and retrofit projects, ensuring optimal noise reduction and safety without requiring modifications to the existing installation.
Steam blow-off silencers are designed to handle intermittent releases of steam or gas at high pressure and temperature. They use a combination of reactive and absorptive elements to achieve effective noise reduction under these peak conditions. Exhaust gas silencers, on the other hand, are designed for continuous flow from engines and turbines. They are engineered to accommodate high flow velocities, thermal loads and gas expansion during operation.
Both types of silencers are custom-designed solutions, but they differ in internal configuration, material selection and design approach, depending on the operating medium and process conditions.
Yes. Silencers can be integrated with ventilation systems, acoustic enclosures or modular system components to achieve higher levels of noise reduction and overall system efficiency within a single installation.
