GLAUNACH H₂ micro silencer

Compact hydrogen vent silencer that reduces the pressure inside the silencer, for lines where some back pressure is acceptable. Designed to ASME BPVC and PED.

Releasing hydrogen produces extremely high noise levels. The H₂ micro silencer takes the pressure reduction inside the silencer, so the noise is reduced where it is generated and the piping before the silencer can be smaller. The result is high attenuation in a compact unit that is easy to integrate, designed to ASME and PED.

Selection data we need

Hydrogen state (gaseous or liquid), mass flow, inlet pressure and temperature, allowable back pressure, inlet size, required noise level, discharge direction and hazardous-area requirements, design code (PED, ASME), quantity.

Applications

  • Electrolysers
  • Hydrogen refuelling stations
  • Hydrogen storage and compressor systems
  • Fuel cell and energy supply systems
  • Hydrogen pipelines
  • Safety relief and pressure release systems

Models: Vent Silencers

Glaunach

GLAUNACH type A absorbing silencer

Circular baffle absorbing silencer in stainless steel with mineral wool and glass fabric lining and a radial diffuser inlet. No pressure drop, 25 dB or more depending on the number of absorber stages.

Glaunach

GLAUNACH type D diffuser silencer

Single- or multi-stage small-bore radial diffuser wrapped in finely woven stainless steel wire mesh. Up to 50 dB in a substantially smaller and lighter unit than an absorbing silencer.

Glaunach

GLAUNACH type DA diffuser silencer with insulated shell

Type D diffuser silencer with an additional glass fabric and mineral wool insulation of the inner shell for better thermal and acoustic insulation of the outer shell.
