Absorptive Silencer Type ACB / ACA

Absorptive Silencer Type ACB / ACA

Application
Medium to high frequency noise reduction at lowpressure drop for: Suction and discharge for centrifugal compressors and blowers Intakes and exhaust for gas turbines Upstream and downstream of pressure reduction valves Suction for engines Its normal pressure drop is 0.1-0.5kPa.

Design
Gas flows through an annular passage lined with perforated tubes backed by multiple layers of sound absorbing materials.

Snubber Type BEO / BMA / BMI

Snubber Type BEO / BMA / BMI

Application
Low to medium frequency noise reduction for: Intake and exhaust of reciprocating engines Discharge for rotary blowers and vacuum pumps Exhaust for reciprocating engines in marine use Its normal pressure drop is 0.5-2kPa.

Design
Gas flows through an arrangement of ported tubes and chambers which attenuate the noise over a wide frequency range.

Diffuser / Absorptive Silencer Type SDA / DA

Diffuser / Absorptive Silencer Type SDA / DA

Application
Vent and blowdown of air, steam and gas to atmosphere for: Safety valves Station and pipeline blowdown valves Process control valves Turbine, compressor and blower bypass Boiler start-up purge systems Steam ejector Its normal pressure drop is 10-50kPa.

Design
Two or more step noise treatment, with each step accomplishing a diffusion and smoothing of the flow, and an overall reduction of noise.
The first stage diffuser provides:
A sturdy shock absorbing section.
A transformation of low frequencies to medium or high frequency range.
The additional stages moderate and smooth the flow while absorbing soundenergy.

Throttle Silencer Type TH

Throttle Silencer Type TH

Application
Safety valves
Process control valves
Turbine compressor and blower bypass valves
Boiler start-up purge systems

Design
Multi diffuser is connected with the inlet nozzle.
It reduces pressure incline and shock wave in the mixing zone between exhaust gas and atmosphere, decreasing shearing stress.
Noise is attenuated through the process.
