Mining Applications

IAC’s mining projects and capabilities are focused on:

  • Noise treatment of OEM equipment to meet mine specifications
  • Design, testing and investigation
  • Attenuators
  • Exhaust systems
  • Acoustic panels
  • Acoustic lining
  • Thermowrap thermal insulation blankets
  • Proven performance on the most noise restrictive mines in Australia. e.g. Bengalla, Mount Arthur Coal Mines
  • Aftermarket supply of thermal insulation (many OEM patterns readily available)

IAC Acoustics Thailand provides varied services for mining applications. They can provide simple secondary silencers or engine compartment lining. They also offer wholistic solutions for individual machinery, with the use of acoustic modelling and noise intensity surveys, to achieve acoustic targets.

IAC has designed and supplied acoustic treatments for almost all types and sizes of above ground mining machinery.

Marine Applications

IAC’s marine projects and capabilities are focused on fabrication and supply of:

  • Dry & Wet Exhausts for shipboard diesel generators and propulsion diesel engines including:
    – Wet & dry silencers
    – Rainmaker water injectors
    – Conventional water injectors
    – Water separators
    – Expansion bellows
    – Wet & dry ducting from stainless steel or GRP
    – Resilient mounting and supports
    – Engelhard soot filters and catalytic purifiers
    – Thermowrap thermal insulation
  • Air inlet silencers
  • Total gas turbine exhaust and air intake systems

Increasingly exhaust silencers and exhaust systems are being asked to provide higher performance while also fitting into smaller or unorthodox spaces. IAC Engineering achieves this through the use of 3D CAD design software and experience in the design of specialised exhaust silencers and exhaust systems.

The Rainmaker model water injectors are specially designed to cool the exhaust gasses faster than conventional injectors. This allows the injector to be installed closer to temperature sensitive exhaust components, like silicone hump hoses or valves.

Our major customers range from Defence Forces, Defence Contractors, Fast Ferries, Luxurious Super Yachts, Cruiseliners, Commercial Shipping and Boating.

Railway Applications

IAC’s rail traction projects and capabilities are focused on fabrication and supply of:

  • Exhaust systems for diesel traction engines and generators including:
    – High performance silencers
    – Expansion bellows
    – Exhaust ducting
    – Resilient mounting and supports
    – Engelhard soot filters and catalytic purifiers
    – Thermowrap thermal insulation blankets
  • Air inlet silencers
  • Airefil storm louvers
  • Air inlet filtration
  • Air inlet ducting
  • Engine compartment acoustic treatment

IAC Acoustics use 3D CAD software and silencer design experience to maximise the available space to fit high performing silencers into unorthodox spaces.

Thermal Insulation Blankets

IAC Thermowrap Exhaust Insulation Blankets are custom manufactured using layered fibreglass materials to provide exceptional heat and noise control at temperatures to 1200°C. Thermowrap exhaust blankets will withstand intense vibration and is the solution for block type insulation requiring replacement.

Thermowrap patterns are created and plotted digitally. Digital patterns further increase accuracy and consistency of the final product. All digital patterns are saved and backed up electronically to allow us to recall previous jobs.
