Exhaust Tailpipe Nanoparticle Testing Example 1
Test Agency: Gastech
Test date: 21/12/17
Analysis Device: TSI NPET
Test protocol: NSW MDG-29
Vehicle: Atlas Copco 6020 U/G Haul Truck
PN from new Freudenberg CRT-DPF: 7000 P/cc
Notes:
• Whilst raw emissions were tested, they were beyond the 6 Million P /cc limit of NPET device.
• Diesel engines are typically putting out in the region of 100 Million P/cc (regardless of Tier level). (Tartakovsky et al. 2015)
• Based on this, the Freudenberg CRT-DPF showed a 99.99% reduction.
P/N in ambient air (Pinjarra WA): 8000 P/cc
Gas coming out of tailpipe was actually cleaner than local ambient rural air.
Freudenberg Filtration Technologies recognise this and test all our Diesel Particulate Filter technologies for both mass and nanoparticle number reduction performance.
Freudenberg Filtration Technologies microfresh® Diesel Exhaust Filters offer the highest level of nanoparticle protection available.
Developed specifically for use in the underground coal mining where miners experience extreme working conditions. The DA filter will help remove diesel particulate from the exhaust of heavy diesel machinery operating underground and in confined spaces.
(Tested to Australian Standard AS 2420)non-flammable to 960°C making it the ideal choice in the explosive atmosphere of an underground coal mine.
In recent tests ( underground mine ventilation air had more diesel nanoparticles in it than the actual exhaust coming directly out of vehicles fitted with Freudenberg Filtration Technologies nano diesel particulate matter filtration ) (nDPMf)
Diesel Exhaust Tailpipe Nanoparticle Testing Example 2
Test Agency: Complete Envirotest
Test date: 16/7/18
Analysis Device: TSI NPET
Test protocol: NSW MDG-29
Location: South Australian U/G mine
Vehicles: Atlas Copco 6020 U/G Haul Trucks
Truck 1 (same truck as Eg 1 above), 3,457 hours on filter
PN from Freudenberg CRT-DPF: 42,552 P/cc
Truck 2, 1877 hours on filter
P/N from Freudenberg CRT-DPF: 45,427 P/cc Freudenberg A/C 6020 DPF
Notes:
No Raw emission results were taken but at the median typical diesel engine level of 100 Million P/cc, the Freudenberg CRT-DPF on both trucks would be operating at 99.96%
Diesel Particulate Nanoparticle Tailpipe Testing Example 3
Test Agency: Complete Envirotest
Test date: 16/7/18
Analysis Device: TSI NPET
Test protocol: NSW MDG-29
Location: South Australian U/G mine
Vehicle: Sandvik DD421 Drill
PN from Freudenberg CRT-DPF: 9,901 P/cc Freudenberg Sandvik DD421 DPF
Notes:
No Raw emission results were taken but at the median typical diesel engine level of 100 Million P/cc, the Freudenberg CRT-DPF on both trucks would be operating at 99.99%
To put these results in perspective……Recent mine atmosphere PN studies at various WA mines.
Mine 1
No real Diesel Emissions Management plan, very few DPF’s (no Freudenberg DPF’s)
Minesite Average: 337 Thousand P/cc
Mine 2
Mature Diesel Emissions Management plan but;
some vehicles still not fitted with effective DPF’s (no Freudenberg DPF’s)
Minesite Average: 60 Thousand P/cc
(In both cases, the mine ventilation air has more diesel particles in it than the actual exhaust coming directly out of vehicles fitted with Freudenberg DPF’s)
No matter where your operation is whether it be underground mining or enclosed confined space Operations Freudenberg Filtration Technologies have you breathing easier.
