Nett GreenTRAP™ NOVA 100 receives US EPA verification

9 May 2017

Nett Technologies of Mississauga, Ontario, announced that it received a US EPA verification for the GreenTRAP™ NOVA 100, an active diesel particulate filter (DPF) system for non-road engines.

The verification is applicable to non-road, 4-cycle diesel engines with or without EGR, rated between 175 and 470 hp (130–351 kW) operated using ultra-low sulfur diesel fuel (15 ppm S). The system has been verified to reduce emissions of PM, HC and CO by 90%.

When the exhaust temperature is above 300°C for more than 30% of the time, the DPF regenerates passively. When engine exhaust temperature is not sufficient for passive regeneration, the DPF is actively regenerated by injecting diesel fuel over an oxidation catalyst to increase the exhaust temperature upstream of the DPF. The active regeneration requires at least 250°C—if the engine exhaust temperature drops below 250°C, the active regeneration is automatically stopped.

The system is fully automated and requires no operator intervention to initiate or monitor the regeneration. The scheduled ash cleaning interval of the DPF is 2,000 hours.

The verification is to be posted on the EPA Verified Technologies List in the near future.
