This is where we come in. GLAUNACH not only supplies mobile and stationary blow-off systems for noise reduction, but also offers many years of experience in the gas market with more than 300 successfully completed projects worldwide.
This expertise allows us to adhere to specific local regulations and fulfill special requests such as custom-fit solutions for hydrogen blending systems.
Natural Gas Vent Silencers
Whether natural gas pipelines, offshore platforms, compressor stations, LNG terminals or gas filling stations – natural gas systems of all kinds have to be serviced regularly. For this, it is necessary to release pressure and blow off gas.


High-pressure silencers reduce extreme noise generated during the venting, decompression, or pressure regulation of natural gas. Without silencers, gas expansion can exceed 160 dB, posing risks to personnel, equipment, and the environment.
Typical applications include:
-
Gas pressure reduction stations
-
Blow-off and safety valve vents
-
Compressor and turboexpander systems
Our silencers are designed to:
-
Ensure compliance with noise regulations
-
Protect hearing and sensitive equipment
-
Handle high pressure and flow rates safely
The mix makes the difference
Natural gas varies in composition depending on its source and is increasingly blended with hydrogen. We analyze the specific gas mixtures and design our silencers precisely to match the corresponding physical properties and operating conditions.
