Clean Diesel Technologies Inc. announced that its Purifilter Plus diesel particulate filter (DPF) emissions reduction system has received an expanded verification from both the Environmental Protection Agency (EPA) and California Air Resources Board (CARB).
Purifilter Plus is now approved for retrofit in 2002 through 2009 model year exhaust gas recirculation (EGR) heavy-duty diesel engines manufactured by International Truck and Engine Corp.
Purifilter Plus, which reduces emissions of diesel particulate matter by more than 85% and meets 2009 nitrogen dioxide emissions limits, combines a passively regenerating ECS Purifilter DPF with the active regeneration components of an ECS Combifilter, resulting in a hybrid DPF which has no minimum exhaust temperature requirement —making it efficient under even the most challenging vehicle operating conditions, according to a company announcement.
The system is easily maintained by the user, the manufacturer said, by periodically plugging the system into a regeneration control panel that may be shared between several vehicles, thus reducing the maintenance requirements when compared to traditional passive DPF solutions.
“These expanded verifications mark an important achievement for Clean Diesel, further expanding our already broad product portfolio of verified retrofit systems,” Charles Call, Clean Diesel Technologies CEO, said. “Our customers can be confident in the capability of Clean Diesel to not only meet stringent EPA and CARB emission regulations, but to achieve these regulations with better performance, lower cost and greater operational simplicity.”
The Purifilter Plus line of products are available in retrofit applications for a wide variety of small and large fleet operators such as municipal, state and utility fleet vehicles, refuse trucks and urban delivery vehicles, which are being required to comply with increasing government-mandated emission reduction requirements.
