NOISE INSULATION ENCLOSURES - ACOUSTIC HOODS

Everest acoustic enclosures are one of the most effective means for containment of excessive noise and for the insulation of the workers from the noise. Even where the silencers are used, they can only treat the air borne noise. The treatment of mechanical noise from the blower, motor etc. is beyond the scope of silencers. Thus, in order to achieve low noise levels, that are often statutory requirements, Noise enclosures/Acoustic Hoods are required.

Everest has developed these acoustic hoods for the blower assemblies and supplied the same to many noise pollution conscious industries such as N.T.P.C., Daliem, Driplex, Ion Exchange (India) Ltd. etc. Everest's economical design provides noise reduction of 12-25 dB(A) bringing down the total noise emitted to safe acceptable limits.



SPECIFICATIONS
Design: The sound reduction enclosures are specially designed to reduce noise pollution to suit the local environment. These are engineered to take care of air intake and outlet, resulting in a pleasing and attractive design

Construction: The robust bodywork of sound reduction enclosures is due to its construction from preformed heavy gauge sheet steel section and its reinforcement with fabricated superstructure. Rubber gaskets are provided to all doors and external joints to resist weathering. The bolted structure provides easy removal of panels for maintenance of servicing of Blowers

Air Circulation: Sufficient cooling air inlet acoustic louvers are provided in the enclosure for efficient air circulation avoiding derating of the machine

Installation: The sound reduction enclosures are preassembled on a support frame and can be easily and quickly assembled at site.

SPECIAL FEATURES
Noise control: noise level reduction to the tune of 25 to 30% is achieved

Mobility: The enclosures can be easily shifted or transported

Ease of maintenance: Adequate space is available inside the canopy for easy maintenance

Elimination of civil work: Enclosures are suitable for open installation and hence require no separate building or shed
