Bulnes Engineering

INDUSTRIAL SILENCERS

Silencers for steam venting, pressurised gases and industrial exhaust systems.

OUR VALUES

Over 40 years of European manufacturing

Consolidated experience in the development and manufacture of industrial noise attenuation solutions.

Advanced technology

We apply technical solutions aimed at achieving effective acoustic reduction with controlled pressure loss.

In-house design and engineering

We develop each silencer according to the characteristics of the fluid, the flow rate, the pressure and the required acoustic level.

Specialised workshop

We have manufacturing and inspection resources adapted to the requirements of each project.

Materials and final product control

We supervise the materials, manufacturing processes and final conditions of each unit.

Technical offices and EPC specialisation

We prepare calculations, drawings and technical documentation for the integration of our equipment into industrial projects.

OUR SILENCERS

Our silencers are designed to reduce the noise caused by the turbulence of high-pressure gases and steam discharging directly to atmosphere.

They are manufactured with a robust outer steel shell and incorporate a reactive diffusion section and a dissipative section. This combination progressively reduces the fluid velocity and the acoustic energy.

Our silencers

OUR TECHNOLOGY

Reactive section

Reactive section

Multi-stage diffusers distribute the flow into numerous micro-jets, progressively reducing its velocity, pressure and acoustic energy.

Dissipative section

Dissipative section

Once the velocity has been reduced, the fluid passes through internal elements designed to absorb and attenuate the noise before discharge.

CONFIGURATIONS

01

Diffuser silencer

Solution with a multi-stage reactive section, suited to applications requiring a significant reduction in pressure and velocity.

02

Diffuser and absorptive silencer

Combines the reactive reduction of the flow with absorptive materials and elements to act over a wider frequency range.
