Blow Down Silencer

Engineered noise control solutions for blow down systems — designed, manufactured, and installed by ARK Noise Control (India)

Why Blow Down System Noise Needs Control

Blowdown operations discharge high-pressure fluids (steam, gas, or two-phase mixtures) to atmosphere, generating noise levels of 110-135 dB(A). These events occur during boiler blowdown, pressure vessel depressurization, and emergency relief, creating severe noise impact on workers and surrounding areas.

How ARK Solves Blow Down System Noise

ARK blow down silencers use a combination of diffuser stages, expansion chambers, and absorptive elements designed for the specific operating conditions of each application. The silencer design accounts for the transient nature of blowdown events, two-phase flow conditions, and the need for rapid pressure relief without restricting flow capacity.

Key Benefits

  • Noise reduction of 25 to 40 dB(A)
  • Designed for transient high-pressure discharge events
  • Handles two-phase (gas-liquid) flow conditions
  • No restriction on flow capacity during emergency blowdown
  • Self-draining design prevents liquid accumulation
  • Materials selected for erosion and corrosion resistance
