Johnson Matthey's New CRT®(+) Diesel Particulate Filter For Stationary Diesel Engines Verified By California Air Resources Board
The California Air Resources Board (CARB), Sacramento, Calif., has verified Johnson Matthey's new CRT®(+) diesel particulate filter (DPF) as a Level 3 Plus system capable of reducing particulate matter (PM) by 85% or greater and not increasing nitrogen dioxide (NO2) emissions beyond the 2009 limit of 20% of baseline NO2 emissions.
As the global pioneer and leader in controlling emissions from stationary engines, Johnson Matthey's CRT filter, which also reduces HC and CO emissions by more than 90%, has revolutionized modern diesel emissions reduction. The CRT(+) DPF is the latest generation of Johnson Matthey's CRT technology, which has the lowest regenerating temperature of any diesel particulate filter technology.
Wilson Chu, Business Development Manager for JM's Stationary Emissions Control Division, said this latest verification is for certified off-road Tier 1, Tier 2 and Tier 3 engines (meeting 0.2 g/bhp-hr diesel PM or less) used in stationary emergency standby generators.
In addition, CARB has conditionally verified the CRT(+) DPF for use in stationary prime generators. This is further confirmation that Johnson Matthey's technologies remain the best available choice for improving air quality.
The CRT diesel particulate filter uses a patented process to oxidize soot in the presence of NO2 at a lower temperature than with oxygen. This lower temperature is compatible with typical diesel exhaust temperatures, so no supplemental heat is required. And this latest generation of the CRT remains a passive device while minimizing NO2 slip.
