Fan & Fan Room Silencers / Duct Silencer

A number of fans for ventilation purposes are found in a vessel. Fan & Fan Room Silencers and Duct Silencer are installed at the inlet or outlet of a fan to reduce noise made by a fan.

NRTEC operates an acoustic performance test facility that is validated to ISO 7235, and designs the silencers with optimal balance of dynamic insertion loss and pressure drop.

NRTEC has developed the world’s first GCU (Gas Combustion Unit) silencer for LNG tank ship for the first time in the world that is used to control noise caused by a GCU system and has been acclaimed by customers as its high quality.
