High class sheet metal fabricated enclosure for reducing the noise level of DG set & also acts as a weather proof housing. Genset will be a integral part of acoustic enclosure and whole construction will be on multi-fold sheet channels & ISMC sections. Enclosure construction is fully bolted keeping in view the major service requirements all doors are provided with specially designed hinges and lockable handles, Battery, Fuel tank is housed inside the enclosure.

ACOUSTIC MATERIALS

Rock wool in the form of slabs of 100 mm thickness and 64 KG/Metric cube density (Specification of Rock wool conforms to IS 8183).

Further to increase the life of Acoustic material resin coated fibre glass cloth is provided on exposed surface of Rock wool slabs and the panels are supported by perforated sheets.

VENTILATION

Acoustic enclosure is designed in such a way that there are no hot pockets around engine and it is provided with suitable designed engine radiator which does not allow the temperature to rise more than 70C above ambient temperature.

To achieve optimal output and minimum sound level from the DG set, suitable openings with acoustic hoods are provide for increasing the inflow of air required for combustion & forced ventilation. Air intake system as per the recommendations and engine requirement are provided.

ù Acoustic hoods with noise splitters provided to block and reduce the sound leakage.

ù The sound control system designed to suppress the sound level to 75 db maximum at 1 metres distance in open free field environment as per ISO 8528 part 10.

SILENCER

Specially designed Critical Grade silencer is provided. Silencer & engine exhaust outlet, Connected with flexible SS below.

VIBRATION ISOLATION

To avoid transfer of vibration from genset to enclosure & surrounding specially designed vibration isolators to be used.
