The Low-Profile CRT(+) DPF system is a passive regenerating diesel particulate filter technology capable of operating at a low exhaust temperature. It is suited for stationary diesel generators used for emergency backup or prime power. The emissions control system reduces PM by more than 85 percent, HC and CO by 70 percent, and meets the 2009 California Air Resources Board (CARB) NO2 limit of 20 percent. The system has a compact, rectangular design, fits all engine sizes and is offered in stainless or carbon steel with a high-temperature coating. It is compatible with ultra-low sulfur diesel (<15 ppm) or B20 biodiesel fuel.
