Thickness of sheet - 16-18 swg
We use high class sheet metal to fabricate these Acoustic Enclosures, which help in reducing the noise level of DG set. In addition to this, it also acts as a weather proof housing. A genset will be a integral part of acoustic enclosure and whole constructions are based on Indian Standard Medium weight Channels (ISMC) sections & multi-fold sheet channels. Its construction is fully bolted keeping in view the major service requirements. All doors are installed with specially designed hinges and lockable handles. Apart from this, fuel tank and battery are housed outside the enclosure.
Acoustic material
It is a compressed glass fibre forming slabs, which is 75-100 mm thick and has 48, 64 kg/m3 density. To enhance the its functional life, it is coated with resin on exposed surface of glass wool slabs and the panel is supported by perforated sheets.
Surface treatment
The entire structure is undergoes weather proof and anti-corrosion treatment along with pure polyester powder coating
Ventilation
Acoustic enclosure are so designed with no hot pockets around engine, rather provided with engine radiator or additional axial flow fan to keep the temperature at 5-7 c relatively with the ambient temperature. These provisions are made to ensure that engines get combustion and cooling air within 2 c of ambient temperature. In order to acquire optimum output and minimum sound level from the DG set, we have installed requisite openings with acoustic hoods to increase the inflow of air required for combustion and forced ventilation. In addition to this, air intake, exhaust fans or single unit velocity axial flow fans are also installed as per the recommendation and engine requirements.
Silencer
It is provided with specially designed low noise silencer. Engine exhaust outlet is connected with flexible SS blow, if old engine is to be provided by the customers.
