Acoustic Enclosures / Soundproof Enclosure |
 |
 |
|
|
 |
 |
 |
|
|
| |
|
|
| The Weatherproof cum Sound Attenuated Canopies ( Modular /
non – modular) are designed for quick assembly and
dismantling for meeting critical requirements of noise
suppression of DG Sets to house the comfortably inside enclosure under extreme weather
conditions, especially in peak summer without derating
& affecting the performance of DG Sets. The sound
attenuated canopies meet noise regulations. The super
sound attenuated canopies meet even the most stringent
environmental standards .
The Acoustic-Canopies consist of basic frames, acoustic Wall paneling / Room paneling/ barriers, top
/ roof segments, natural & forced (optional) ventilation - fans or blowers, inlet-outlet ventilators frames, ducting, partitions etc. Genset ratings from 2.5 to 2000 KVA, applicable to all types of gensets - air
& water cooled.

320 KVA Silent AMF
DG Set – 72
dB
A at
1 meters
distance |
Besides,
the existing Power Houses, DG Rooms, etc. can be converted
into Silent Power House, too, by incorporating the
required Acoustic panels / barriers, forced ventilation
system without affecting the rated performance of DG Set |
|
|
|
| |
 |
|
The Enclosure is Categorised Basically in Four Parts
|
|
|
1. |
The precaution has been
taken in the design of Enclosures to reduce different & higher level sounds created at
various locations while DG Set is running. |
2. |
Temp. : As
far as ventilation is considered. The OSE enclosures are provided with
forced & natural ventilation system which enables the
fresh air inlet to engine breathing, cooling & throws
out hot air outside considerably.
Special precautions are taken for Engine Air Filters which
is directed allowed to suck the Fresh Inlet Air for Engine
directly from atmosphere |
3. |
Whether Proof : All the
precautions has been taken to withstand the All types of climate conditions & seasons like winter, monsoon,
summer, etc. |
4. |
Maintenance : Sufficient space is allotted inside to
fit different accessories like batteries, etc & the
maint. can done inside with the easy movement of the
working person on DG Set. |

The
"OSE" Series enclosure features include :
|
Highly
Corrosion Resistant Construction / Structure
|
|
• |
Body made
from CRCA Steel, 16 SWG with high Accuracy level, with highly
skilled
experienced staff, welded with jigs & fixtures, which can
accommodate 50 mm to 100 mm Acoustic Lining for various ranges of
DG Sets from 2. 5 KVA TO 2000 KVA. |
• |
Various ports / partitions / louvers are provided for the canopy
to suit the application & as per the type of DG Set – air /
water cooled to fit the required accessories to couple DG Set with
canopy, Considering exhaust piping, engine suctions, forced
ventilations, bellows for radiators, etc. |
• |
Z / C / Other,
(if required) sections are used to form box type panellining,
which facilitate easy & uniform filling of Acoustic material -
glass wool of high & required density, with the help of
perforated MS sheet (AL. Perforated sheet optional). |
• |
Rubber
Gaskets / Silicon sealant are used wherever required to fill up
the typical gaps, if any. |
• |
The precaution
is being taken for the heat radiation & conduction through the
exhaust system. All the exhaust piping (except engine exhaust
manifold, expansion below) inside canopy is lagged with asbestos
lagging / Aluminium cladding. |
• |
To
ensure suffient space inside enclosure, & for higher ratings,
the silence (residential) is provided/fitted outside & top of
the canopy. |
• |
Stainless steel
locks and hinges. |
• |
Zinc
plated or stainless steel fasteners. |
• |
Sheet
steel components pre- treated with zinc phosphate prior to
Painting. |
• |
Excellent
Access for maintenance. |
• |
Easy access for Radiator coolant / water filling. |
• |
Lube
oil and cooling water drains piped to exterior of the canopy. |
• |
Full length
extra wide doors /
sliding doors on each side. |
• |
Safety
glass control panel viewing window in a door; Emergency stop
button mounted on canopy exterior. |
• |
Cooling
fan and battery charging alternator fully guarded. |
• |
Fuel
fill and battery (with stand) can only be reached via lockable
access doors. |
• |
Exhaust
silencing system totally enclosed / lagged inside for operator
safety. |
|
| |
|
|
|
Lifting
points on base frame for non-modular enclosures.
|
| |
|
|
|
|
• |
The noise level
reduction is ensured by 25 dBA at 1 Mtrs.than the specified sound
levels of Engine manufactures, which is normally 100 (+5 DbA), in
open atmosphere. |
• |
Noise
level, on average below 75 dBA at 1 M in open atm. & 65 to 70
dBA at 1 M in open atm for Super Sound Attenuated Canopies. |
• |
No
duration applicable for DG Set if housed in Enclosure. |
• |
Enclosures are whether proof / suitable for open air installation. No civil work is required, except
bottom sealing. |
• |
Sufficient
space for Routine. Breakdown maintenance. |
• |
Air
filter is allowed to suck fresh air, which is breathed by Engine
required for proper & complete combustion of fuel. Normal
temp. Difference in bet. Ambient air temp. & Air inlet temp.
To air filter is 10 deg. cel. (+ / - 5 deg. cel. normally depends
upon the site conditions, & the difference increases if amb.
temp. is above 40 to 45 deg. cel.) |
• |
The
Enclosure is supplied with or without space for fuel tank &
panel. Enough space to house panel and Fuel Tank inside canopy
(optional). |
• |
Heavy-duty
sturdy steel base frame for placement of D.G. Set (optional as
canopy base). |
• |
Provision
of Air-Intake / Ventilators and Air-Exhaust silencer's for
preventing leakage of sound. |
• |
Openable
doors / sliding doors for easy access to virtually every part of
D.G. Set for comfortable maintenance. Doors are Sound Reduction
High Performance most comfortable Sound Reduction level to 70-75
db at a distance of 3 meters. |
• |
Forced Ventilated Air-Circulation system using Axial Fan's as per
engine requirements. |
• |
Separate Duct for ventilating hot air coming out of engine (In
case of Air Cooled Engines) / Radiator duct for water-cooled
engines. |
• |
It can be dismantled completely & engine is accessible from
all the (sides) Easy Modular Structure, Easier Installation. |
• |
Suitable for both indoor and outdoor installation. |
• |
Provides excellent access for normal operation & routine
maintenance. |
• |
Construction is rugged, durable and virtually maintenance free. |
• |

|
• |
Modular design for ease of assembly/disassembly in the event of
major breakdown repairs. |
• |
All material used are of fire-resistant/retardant grade. |
• |
The Acoustic Enclosure is Environment Friendly as they are
protected against weather dust rodents and have in built thermal
protection. |

|
|
We have excellent trained team of engineers to erect canopies in
any area, basements, rooftops, on trucks or trailers, rigid
frames, in industry or diverse applications. |
