Johnson Matthey Releases New CRT (+) DPF System

Posted on September 1, 2010

Johnson Matthey has a new low-profile CRT (+) DPF system that meets the California Air Resources Board’s nitrogen dioxide limit of 20%. The system was also designed to reduce particulate matter by more than 85%, as well as hydrocarbon and carbon monoxide by 70%.

The system is a passive regenerating diesel particulate filter (DPF) technology that can operate at low exhaust temperatures. According to Johnson Matthey, the system can be applied to all stationary diesel generators used for emergency backup or prime power. The system is offered in stainless or carbon steel with a high-temperature coating, according to the company.

The system also features a two-component design in which the platinum-coated catalyst is positioned before and separate from the filter to protect the catalyst from soot.
