APPLICATIONS
GENERATORS

Generators are used alongside HVAC applications as back up power for critical applications such as Healthcare, Data centers and education. They may also be installed in telecom boosting stations. These generators are loud when turned on and may cause local municipal noise by law infractions. Noise from generators can be an irritant to both people within the building and those outside of it.

SPACE
CONSTRAINTS

Problem

ExclamationMark_green_outline

Generator rooms are usually short of space. With transition pieces required at the exhaust side, there is little room to install a silencer long enough to provide the required performance. To install a silencer long enough, valuable real estate needs to be sacrificed.

Solution

Vibro-Acoustics designs transitional rectangular silencers that eliminate the need to provide separate transition pieces. The silencer is built into the ductwork and can provide the required performance without sacrificing valuable real estate.

AERODYNAMICS

Problem

ExclamationMark_green_outline

Generator radiator fans are low static fans. When silencers are selected based on ideal catalogue conditions, they do not take into account the system effects that come into play in the real world. The actual pressure drop goes up beyond the capacity of the radiator fans, causing overheating and tripping of the engines.

Solution

Vibro-Acoustics silencers are designed with actual conditions in mind. Installed pressure drop in silencers does not exceed the radiator fan capacity, thus ensuring that the generators do not overheat.

RADIATED
NOISE

Problem

ExclamationMark_green_outline

Noise radiated from generators can be loud enough to penetrate the walls of the generator room and cause nuisance for people within the building and outside of it.

Solution

Vibro-Acoustics uses a combination of plenum panels, absorption panels and louvers to control noise radiated from the generator.
