powered by Hushpak Engineering
Hushpak designs, manufactures and installs attenuation solutions for mobile machinery, specialising in reducing noise at the source.
Our attenuation products achieve significant noise reductions without compromising engine efficiency or operability.
Our attenuation treatment for mobile machinery includes dozer attenuation kits, exhaust and muffler systems, fans and louvres.
Knowledge of the mechanical aspects of mobile machinery and engineering, together with acoustic monitoring and engineering analysis, ensures your noise problem is effectively resolved.
We have several products available to reduce noise of heavy vehicles. We select superior materials that withstand harsh conditions and we manufacture replacement parts.
Dozer Attenuation
Dozer attenuation packages or dozer kits, address the numerous operating scenarios that generate track noise. To date, we have reduced dozer undercarriage noise by up to 6 db(A). Noise attenuation packages are also available to treat exhaust, engine bay and cabin noise.
Mufflers
Hushpak manufactures and installs custom designed exhaust and muffler systems to reduce noise output on heavy vehicles/mobile machines including haul trucks, dozers, excavators and drilling rigs. Hushpak has an unrivaled reputation for successful noise control with minimal equipment installation and lower cost – without causing high exhaust backpressure.
Our acoustically engineered mufflers are designed to replace original mufflers with relative ease, without requiring expensive modifications or excessive down time. Using the latest sound suppressing technology, analysis and superior materials, our mufflers reduces noise across both high and low sound frequencies. Hushpak mufflers achieve noise compliance and meet OEM specifications for exhaust backpressure.
Hushpak’s performance mufflers and exhaust systems are custom designed and acoustically engineered to achieve the following:
- Sound-damping of both high and low frequency tones
- Minimal air flow restriction and backpressure
- Minimal equipment weight and bulk added to vehicle
- Ease of installation without extensive modifications or time delays
- Improved machine serviceability
Acoustic Enclosures
Hushpak acoustic panels and enclosures attenuate and absorb sound and vibration. Enclosures have been designed for a range of mobile machines and can be customised to suit specific equipment. Existing enclosures can also be upgraded to further improve noise attenuation.
Acoustic Fans and Louvres
Designed and installed to incorporate low air resistance with aerodynamics, to minimise sound emissions whilst ensuring appropriate air flow and ventilation. Hushpak fans and louvres are usually custom built for specific applications.
Hushpak designed, manufactured and installed a muffler and fan package for a Liebherr 996 excavator. The solution achieved compliance at low cost, whilst improving accessibility and engine cooling. Read more…
Working together with a mining service provider, Hushpak set out to eliminate maintenance issues and ensure noise compliance for a CAT 793D haul truck. Hushpak replaced its original muffler with a custom designed muffler specifically developed to treat the problem frequencies associated with the CAT 3516B HD engine. The new muffler successfully reduced noise output to under the in service noise limit, and eliminated maintenance accessibility issues. Read more…
Hushpak designed and built a custom Acoustic Treatment System to attenuate noise levels from a Bradford Breaker. The solution incorporated Hushclad acoustic cladding, and achieved a 10dB(A) reduction in noise levels. Read more…
