INALOUVER ND
ACOUSTIC LOUVER
Acoustic louvers or grilles are commonly used at air inlets and outlets of noisy enclosures (engine rooms, compressors, transformers, motors, etc.), and to create acoustic barriers and screens.
INERCO has several models of acoustic louvers and grilles, adaptable in design, acoustic attenuation, air flow, available spaces, pressure losses and % of open surface.
It is suitable for a wide range of applications:
INDUSTRY
FOSSIL POWER PLANTS
BUILDING
OIL & GAS APPLICATIONS
