3. Where we started
• 1991 : 400m2 premises
• Produced exhaust gas silencers and air intake attenuators
• 1994 : moved to a 900m2 premises nearby
• Became a major player - supplying diesel engine manufacturers,
generator set builders and mechanical services installers
• Expanded product line to meet demand for products such as:
• Boiler blow-down and steam, air and gas vent silencers
• Small gas turbine silencers,
• Stand alone catalytic converters or combined catalytic silencer/soot filters.

6. Exhaust
Silencers
• Designed to meet the requirements of every application
• Use reactive and absorptive principles, or a combination
• From basic industrial absorptive silencers to super-critical silencers
• Can incorporate spark arrester with DNV or ATEX approvals
• Variations to suit restricted space or unusual configurations
• Can incorporate catalyst or NOx filtration systems
• Our own in-house test facility.

7. Combustion
AirIntake Silencers
• Noise is generated when air is drawn into large engines
through turbo chargers or compressors
• Our solutions use various forms of annular or rectangular
intake silencers, to suit the flow system
• Designs include simple absorptive silencers, those with a
central pod, or annular splitter types
• Solutions for very large intake flows include single or
multiple-framed banked systems or rectangular parallel-type
splitter units.

8. Catalytic
Converters
• IMS supply an exhaust gas catalyst to reduce engine emissions
• We supply three major kinds of catalytic converters:
• Single-stage oxidation - reduces only carbon monoxide (CO)
• Two-stage oxidation - reduces carbon monoxide and hydrocarbons (HC)
• Three-stage SCR - reduces nitrous oxides as well as CO and HC
• For durability, stainless steel substrates are used
• Innovative construction maximises the surface area
• Can be installed as stand alone units or integrated into
an exhaust gas silencer.

9. Atmospheric Vent
Silencers
• Attenuate noise produced by gas or steam at elevated
pressures expanding to atmospheric pressure
• Two-fold purpose:
• Reduce work-place noise levels
• Reduce industrial noise intrusion into residential areas
• Typical used within steam ejectors, steam and gas vents,
process vents, turbine or compressor bypass systems and
safety and relief valves.

10. Generator
Canopies
• We build generator canopies to protect both machinery and
operators
• Variety of weather canopies and acoustic canopies
• All manufactured to a high specification from a zintec steel
body, preformed into sections and welded to form a rigid
structure
• All panels are constructed of non-combustible materials
• Wide choice of options, accessories and services.

11. Air Inlet & Extract
Attenuators
• Machinery in plant rooms can cause problems with
ventilation and noise in adjacent areas
• Our noise-reducing product range suits all requirements,
including:
• Acoustic louvers
• Splitter attenuators
• Fixed blade weather louvers
• Full range of louvers for harsh environments,
• All designed and constructed at our purpose-built facility
to the most stringent standards.

12. Acoustic Doors
• Excessive noise affects health and hearing, so efficient
protection is required
• IMS manufacture single and double acoustic doors with a
choice of three levels of sound reduction - 30dB, 38dB and
45dB - for high degree of noise control
• Double-skin construction of zintec steel from 1.6 to 3mm
thickness
• Standard features such as lockable slam fastener and double
Schlegel-type door seal
• Many optional features available to suit different
applications.

13. Components &
Accessories
• Comprehensive range of components to complement our
silencers - from the simplest bolt to a complete system
• Accessories include rain caps, flanges, gaskets, bolting sets,
pipe work, expansion bellows, flexible pipe, elbows,
brackets, hangers and guide
• Supplied as loose items or fabricated parts to suit all types
of installations
• Thermal and acoustic insulation.
