Preset Vent Silencers

The most economical solution for small applications

Description
Technical Data

Vent silencers are used to control the very high noise levels associated with venting pressurized gases to the atmosphere, such as steam, natural gas, air, hydrogen, oxygen, nitrogen or any other combination of compressed gases.

Burgess-Manning vent silencers are typically installed on relief, safety, control, start-up and vent valves, including applications such as autoclaves, in steam boilers, HRSGs, gas compression systems and similar equipment.

They are widely used across industries such as power generation, oil & gas, chemical processing, industrial manufacturing and utilities, as well as in any application where pressurized gases are vented to the atmosphere.

To meet the rising demand for standard, in-stock and ready-to-ship vent silencers, Burgess-Manning has developed a dedicated range of Preset Vent Silencers. This range provides you with the lightest silencer in its class with immediate shipment, enabling rapid resolution of on-site noise issues.

Our optimized standardized design combines compact dimensions with reliable acoustic performance across a defined range of flow conditions, while maintaining Burgess-Manning’s highest manufacturing and quality standards. All Preset Vent Silencers are self-supported on the discharge pipe and supplied with either a butt-weld or flanged inlet connection.

Relevant Industries

Oil and gas refineries, natural gas processing plants and LNG facilities represent remarkably intensive and acoustically challenging industrial environments, generating intense noise levels from complex processing equipment, high-pressure systems and continuous operations. Hydrocarbon processing facilities require comprehensive noise control solutions to ensure worker safety, regulatory compliance, community relations and operational efficiency.

Power plants generate both energy and significant acoustic energy.Excessive noise can endanger employees, affect equipment longevity and violate local and international regulations. Burgess-Manning custom-engineers silencers for turbines, compressors, blowers, generators and transformers.

Industrial applications generate considerable noise as a result of high-capacity machinery, continuous operations and complex infrastructure. Without proper noise control, these environments can pose risks to employee health, disrupt surrounding communities and violate environmental and occupational noise regulations. Implementing tailored noise mitigation solutions of acoustic walls, noise barriers and silencers while utilizing acoustic modeling, CFD, FEA and noise measurements to design solutions not only supports safety, but also enhances operational efficiency and community relations.
