APPLICATION

The Model RCS silencer provides high performance flow path pulsation and noise control for compressors or blowers running at constant RPM. The RCS silencer is well suited for use with lobe type blowers and positive displacement compressors that produce high amplitude, low frequency pulsations in critical environments with stringent noise control requirements. The RCS silencer design utilizes a tuned series of reflective internal discontinuities to filter undesirable pressure pulsations from the flow stream.

In the most stringent noise requirements, final stage absorptive technology can be applied for further treatment of broadband noise generated by rotating equipment. For blowers that use a liquid injection sealing/cooling system, the RCS silencer can be designed with optional water and mist separating capability.

WATER SEPARATION

The process flow stream enters the silencer through the silencer inlet connection at a tangential orientation to the vessel shell. As the flow stream follows a swirling path along the inside diameter of the vessel, any water that may be entrained in the flow stream is separated by centrifugal force and falls to the bottom of the vessel where it can be piped away to a drainage location.

Options

• Flanged inlet and discharge connections

• Separate reactive and absorptive modules

• Side or end inlet

• Side or end inlet

• Custom support structures

• Dual layer outer shell with intermediate constrained-layer damping membrane (reduces shell transmitted noise)

• Custom exterior/interior coating systems

FEATURES

• The heaviest construction in the industry, designed to eliminate vibration and/or acoustic fatigue failures

• Multiple reactive chambers, computer tuned to reduce pulsations a minimum of 95 percent at the blower fundamental frequency

• Special reactive design providing effective pulsation control over the first three harmonics (multiples) of the fundamental frequency

• Pressure drop reducing features to insure maximum performance with minimum blower efficiency impact

• Absorptive discharge module with multiple stages to attenuate residual broadband noise

• Computer assisted custom designs to match the silencer design to the project/site requirement.
