Increase reliability, safety, and performance while reducing maintenance time and cost with Emerson's innovative technologies.
Industry is driving down noise requirements
High flow and high pressure drop processes can get very loud, very quickly. Allowing this noise to continue puts you at risk of personnel safety issues, equipment damage, and environmental agency violations and penalties.
Path treatments, such as acoustic insulation, only mask the damaging noise effects coming from inside the pipeline. Source controls, such as diffusers and control valve trims, work to lower noise levels but can come with limitations in flow capacity and the potential to become clogged with particulate.
Using additive manufacturing to accelerate new product development
Boundless Design Potential
With additive technologies, intricate geometries no longer mean complicated or time-consuming build processes. By adding materials layer by layer, the manufacturing process becomes simpler, faster, and results in less material waste. It also allows us to broaden our design potential in order to solve more complex problems in new ways.
Rapid Prototyping
Using additive manufacturing, we're able to create parts in-house, so that design iterations can be tested, evaluated, and adjusted much faster and with less scrap than before. With the ability to get the most ideal version of the product to market quickly, we can address your process issues before they are compounded.
A full-bore noise reduction solution
The Fisher WhisperTube 6060 modal attenuator is a simple, passive device offering 15 decibels of noise reduction for noisy gas or vapor applications. Uniquely, it reduces noise inside the pipe for all sources upstream of it and generates no pressure drop, so there is no impact on process flow. Install it downstream of the control valve or other equipment contributing to system noise.
Additional Product Benefits
Application Versatility: The WhisperTube is designed for a wide range of fluid flow rates and temperatures. It can operate at temperatures ranging from -50°C to 371°C (50°F to 700°F).
Sour Service Capability: NACE MR0103, MR0175 / ISO 15156 compliant materials of construction are standard for applications involving sour gas or vapor.
Reliable Performance: There is no internal acoustic packing material in the WhisperTube to fail from moisture absorption. A cast internal drain channel ensures any potential liquid buildup can be removed, ensuring optimum performance.
Webinar
This webinar introduces you to WhisperTube, a full-bore modal suppression device that does not take pressure drops but provides noise reduction. This unique offering can be utilized in various noise reduction applications where conventional solutions have inherent limitations.

The Severe Service App
Expertise at your fingertips
The Severe Service app is available for iOS and Android devices. Download it from the App Store or Google Play.
Emerson's Severe Service app is developed for process control engineers in need of quick and easy control valve diagnosis and maintenance for the most difficult installations within process plants.
Features of the app include instant access to Fisher control valve sizing tool, severe service control valve diagnosis information, a large technical library and a severe service industry application library to keep users up-to-speed on severe service topics with educational videos and reference collateral.
Severe service control valves are used in the most difficult installations within a plant and can fall victim to common issues such as cavitation erosion, high pressure, and other environmental challenges. The Severe Service app can help maximize the longevity of these critical assets so end users get the most from their investments while protecting employees, the environment and other plant assets.
