Designed for hard rock mines and base metal mines

    Mammoth’s Passive Regeneration DPF's are specifically designed for hard rock mines and base metal mines sensitive to NO2 and high exhaust temperatures. Our Passive Regeneration DPFs provide the best combination of low-temperature regeneration and low No2 levels allowing for better performance and safer environment.


    Learn how DPF regeneration works


    An excellent example of the overall performance of Mammoth’s Passive Regeneration DPFs was on a hard rock mine in Northern Ontario. The site ran a fleet of CAT AD30 haul trucks in varies haulage cycles. Mammoth installed a DPF system for a 200-hour trail run.

      The trial results showed that the back-pressure remained below the alert level. Other significant benefits included:
      • Reduced DPM (particulate) levels by 98% at the tailpipe
      • Reduced CO by 90% • Reduced NO2 by 17%
      • Did not cause any significant increase in NOx levels
      • Eliminates downtime
      • Easy install lightweight solution

      The underground operators on this site said that “the system allowed for cleaner air, greater visibility and working conditions.”

      The Komatsu 830 haul truck has an impressive payload capacity, and excels in efficiently transporting substantial volumes of minerals over challenging terrains. Prioritizing safety, the Komatsu 830 incorporates advanced braking systems and stability controls, creating a secure working environment for operators. Extensively used in large-scale mining operations, the Komatsu 830 proves indispensable for optimizing logistics, streamlining workflows, and meeting production targets. One of the challenges with the Komatsu 830 is Selective Catalytic Reducto r ( SCR ) clogging or crystalizing.

      What does SCR stand for? SCR, meaning Selective Catalytic Reduction, is an advanced emission control system in diesel engines to reduce the levels of harmful nitrogen oxides in exhaust gases. SCRs are a critical component for cleaner air, better fuel efficiency, and compliance with emission standards.

      The need for mining is becoming increasingly more essential in the supply of raw materials. Mining is also one of the most perilous professions, with miners exposed to numerous risks, including fires and burns. Mammoth’s thermal blankets can play a crucial role in safeguarding miners against the devastating effects of fires and thermal injuries. Mining Risks: Mining operations frequently occur in confined underground spaces, where ventilation is limited, and the risk of fires, explosions, and thermal injury is high. Fires in mines can spread rapidly due to the lack of oxygen and limited escape routes. The Role of Thermal Blankets: Thermal blankets , also known as fire-resistant or heat-reflective blankets are supplied by manufacturers such as MacLean, KES, RDH, J&S Walden, RockTech, Normet, and Getman, are constructed from advanced materials designed to withstand extreme heat. Mammoth thermal blankets are portable and easy to apply to various mining equipment, including boom trucks, scissor decks, transmixers, Anfo loaders, shotcrete machines, fuel trucks, and water trucks. Reduce your fire risk and thermal incident rate: Mining machines receive routine maintenance and repairs, so it is common for thermal blankets to be left off mining equipment after repair work is completed. This is often because mechanics find handling the thermal blankets uncomfortable and itchy , as well as hard to install. Operating heavy mining equipment without thermal blankets is a risk because hose leaks can cause fires when flammable fluids meet hot exhaust . Reduce the fire risk at your mine site by implementing a double check for thermal blankets after routine maintenance work. You can get support from Mammoth Equipment to manage your fire risks with Easy-apply and remove Mammoth blankets Onsite training for installing thermal blankets A custom fit blanket kit specific for your equipment model and engine Overlapping blankets (like shingles on a roof) to prevent any gaps and hot spot exposures on your equipment Some visual differences between regular and Mammoth blankets:

      Mammoth recognizes the impact of having equipment down on mining operations. The CAT 793C haul truck is a common machine found on many sites globally. As a result of discussion with many site mobile maintenance teams, Mammoth has reverse engineered the exhaust kit for this haul truck with the C175-16 engine. This includes: Pipes 156-6237 2W-9078 156-6247 8X-3361 8X-3360 8X-3135 7C-3337 155-0528 242-8869 8X-3142 Mufflers 7E-6811 Brackets 8X-3130 8X-5103 8X-2850 8X-3128 8X-3132 Clamps 1W-4161 2W-8851 7E-8452 6N-9298 Improvements made by the Mammoth engineering team have proved to extend component life and increase equipment uptime . Some of the improvements made include upgraded flanges, heavy gauge steel pipe with fitted blanket kit available and enhanced exhaust flex bellows . All components are a direct fit replacement to the OEM factory supplied components for easy, simple and quick installation. Components stocked at multiple warehouse locations across North America.
