Dual Skin Exhausts | High-Performance Thermal Protection for Industrial Equipment

Dual Skin Exhausts

Why Choose Our Dual Skin Exhausts?

Mammoth designs and manufactures a comprehensive range of exhaust systems and components that are guaranteed to fit and built to last. We supply OEM exhaust systems from leading brands like Caterpillar, Hitachi, Komatsu, Liebherr, and Volvo. Our systems are designed to fit existing brackets and footprints, allowing for easy removal and replacement without modifications.

Benefits

Locally Manufactured
Our exhausts are produced in one of our seven global fabrication facilities, ensuring compliance with local regulations and fast turnaround times.
Thermal Reduction
Made from corrosion-resistant, heavy-duty aluminised steel, Mammoth’s exhausts reduce touch temperatures by up to 150°C, minimizing surrounding engine heat and the risk of burns or heat-related injuries.
Maintenance-Free
Once installed, our Dual Skin Exhausts last the life of the engine, with easy cleaning and maintenance similar to standard exhaust systems.
No Modifications Needed
Our exhausts are engineered to fit into existing brackets and frameworks with little to no modifications required.
Quality Materials
Fabricated from durable, corrosion-resistant aluminised steel with up to 25mm internal insulation, our Dual Skin Exhausts are built for maximum efficiency and longevity.
Sound Attenuation
Sound attenuation mitigates the propagation of sound waves, thereby reducing noise levels and improving acoustic conditions.

Dual Skin Exhaust Composition

Inner Layer
Made from aluminised steel with a low thermal expansion coefficient, reducing deformation under heat stress.
Needed Felt
25mm thick non-combustible insulation that absorbs heat and reduces surface temperatures by up to 80°C.
Outer Layer
Additional aluminised steel layer for enhanced thermal reduction and durability

Features

External V-Band Joints

Standard Dual Skin systems often fail to mitigate high surface temperatures at joints. Mammoth addresses this with External V-Band Joints, which offer:

Heavy-duty flanged connections for added thickness at joints, minimising thermal conduction.
Prevention of hot spots and ignition sources, enhancing overall system safety.

Thermal Assessment Capabilities

In Q1 2022 a North American Gold Mine had a fire event on site. To mitigate the risks of fires from occurring, the site’s mobile maintenance team engaged Mammoth to carry out thermal audits across their Load, Haul and Ancillary fleet.
The deliverables included; identifying potential fire risks and recommending controls to reduce touch surface temperatures below the flash point of flammable fluids.

Sound Attenuation

Komatsu 930E grid box and exhaust attenuation

The client operated an open cut coal mine in NSW. The sound power target for its fleet of Komatsu 930E trucks was set at 120 dB(A) to meet the boundary noise requirements. The current noise level was recorded at 124 dB(A), 4 dB(A) louder than the prescribed limits.

Sound Attenuation

Hitachi EH5000 Sound Suppressed Exhaust System

A site running Hitachi EH5000 trucks that were fitted with standard sound suppression mufflers was having issues with them due to high back pressure, cracking and falling apart prematurely. The current mufflers were not meeting the sound reduction requirements the site was seeking to achieve. The client was exceeding boundary noise limits due to upscaling of fleet size and required noise reduction to be achieved on existing trucks to continue mining at night.
