Vent silencers are used in conjunction with systems that utilize a pressure relief valve. When gas is released to atmosphere it can create excessive noise that can be objectionable to surrounding areas. Typical applications for vent silencers include oil & gas, industrial and chemical processing, heat recovery systems and steam boilers. Dürr Universal vent silencers are used around the world in a wide range of applications, including steam vent silencers for industrial applications and blowdown silencers for gas compression stations.
