Liebherr

 

Liebherr is a leading original equipment manufacturer (OEM) and supplier of components and Liebherr exhaust systems for the mining industry. With its innovative technology and comprehensive expertise, Liebherr continues to play a pivotal role in shaping the future of the industry. Minetek have a long-standing relationship with Liebherr providing sound attenuation solutions across their entire range of mining machinery to help reduce machine noise levels. Our acoustically engineered and custom-designed Liebherr exhausts are designed to reduce machine noise levels.

 

Liebherr Mufflers 

 

Minetek understands the importance of high-quality equipment and the impact that machinery noise has on production. That is why we offer extensive machinery noise reduction solutions across a range of OEM models, including Liebherr Caterpillar, Hitachi and Komatsu exhaust systems. Our engineered sound solutions are manufactured with precision, state-of-the-art processes, and quality checked for performance whilst reducing machine noise levels. Helping mine sites operate efficiently without exceeding or breaching regulatory noise levels and restrictions.

Each element of Minetek’s Liebherr exhausts is designed specifically for that machine with sound combinations that work effectively with the acoustic frequency. It is the mixing and matching of these elements, determined by our acoustic engineers that underpin the engineering of Minetek’s Liebherr muffler design. With cutting-edge technology and simulation programming, we can enable Liebherr exhausts to target specific frequencies, including balancing and noise-cancelling.

 

Liebherr Exhausts & Mining Machinery  

 

The mining industry is one of the most challenging environments imaginable. Many work sites are remote, conditions are extreme, and the stakes are high – lives depend on the successful operation of complex machinery. In such an environment, it is essential to partner with a company with a proven record of accomplishment of safety, reliability, and innovation.  

Minetek works with OEMs like Liebherr to produce the world’s quietest and most efficient mining equipment. With over 1,500+ mining machines attenuated, Minetek’s sound attenuation solutions can help reduce noise levels by up to 12 dBA, engineered to maintain productivity and minimise the impact on operators and maintenance teams. Our quality, reliability and innovative sound reduction technologies have been proven repeatedly in some of the most challenging conditions. When you partner with Minetek you can be confident that you are receiving the best possible support for reducing noise levels at your mining operation. 

We work with OEM’s such as Caterpillar to produce the world’s quietest and most efficient mining machinery. With over 1500+ machines attenuated our sound attenuation solutions can help reduce noise levels by up to 12dBA. Minetek’s modular sound suppression kits are available for Caterpillar mining trucks, excavators, dozers, loaders and drills, with certified install teams available globally.

The ability to deliver equipment on time has been a feature of our dealing and we haven't had a situation where a variation has been requested. The quality of their workmanship has been good and the capability of hardware has been as expected or better than quoted”

CS Energy Kogan Creek Power Station Services Superintendent

Good product with great service leads to a great outcome. My dealings with MINETEK WATER and their supply and service of evaporator fans was one of high quality. I installed 10 evaporator fans on climate control to maximise efficiency and the results were incredible. From the first meeting through to commissioning nothing was a problem for the MINETEK WATER team. I would highly recommend this product to anyone with water disposal issues.

Integra Coal Operations Coal Handling & Preparation Plant (CHPP) Manager

The relatively small fans allowed us to utilise our existing bulkhead, where we were severely limited by space, which allowed us to use our existing infrastructure and dramatically reduce downtime in the mine during the change out. The installation was completed safely... and allows us to scale our ventilation flow with their pressure on demand system to suit our production profile.

Saracen Thunderbox Underground Manager

We found the MINETEK WATER team listened and supported our situation with helpful guidance and advice to layout the evaporator pipework maximising their efficiency. I would highly recommend the units to others needing a cost effective solution to excess water.”

Osborne Gold Mine Superintendent Environment

Our evaporators are still performing flawlessly and working absolutely great. They have been running 24/7 without a single hiccup. Thanks again!
