Istiq
Acoustic Canopy is designed to comply to the DOE regulation.
The canopy are equipped with Discharge, Intake and Exhaust
silencers. The noise level is designed to achieved 70 to 75
dB(A) measured at 3 meter away.
In
selecting a silencer for a canopy, a balance between noise
reduction, pressure drop and heat rejection need to be calculated
cautiously By using internally developed software, ISTIQ Noise
Control can help to make the right choice quickly and most
importantly, accurately.
Introduction
Canopy application for housing a generator set has gaining
its popularity over the years. This is due to a portability
of the set to be from one place to another and furthermore
the cost for housing a generator set is cheaper as compare
to a normal concrete house.
Construction
The body of the canopy uses only the rockwool and protected
with perforated G.I.
Our
company has developed the modular system panel which provides
great flexibility at low cost. The panel are standard 65mm
thickness, formed from 2.3mm mild steel, inert acoustic infill
and galvanised perforated inner sheet steel. The finest quality
materials and workmanship ensure that a final solution gives
the best in noise control without affecting airflow, operation,
maintenance or inspection.
Exhaust
pipe which is inside the canopy must be insulated to avoid
overheating problem. The exhaust lagging is done by using
rockwool as thermal insulation wrapped with aluminium jacketing.
Fuel
tank is located at the base frame. The designed therefore
will serve dual purposes - acting as a supporting base and
fuel tank. The body and the base can be separated for maintenance
(genset overhaul) in the future.
Windows,
exhaust penetrations, radiators and electrical cables, fitting
and fixtures are all standard. Standard Material Specification
