FREQUENTLY ASKED QUESTIONS
GreenTRAP™ 300 Common Questions
Find answers to the most common questions about GreenTRAP™ 300, particulate matter (PM) reduction, regeneration, and emissions control for stationary diesel generators used in standby, prime power, and continuous-duty applications.
What is a Diesel Particulate Filter (DPF)?
A Passive Diesel Particulate Filter (DPF) or GreenTRAP™ is an exhaust aftertreatment system designed to capture and reduce diesel particulate matter (PM) from stationary diesel generators. Using wall-flow filtration technology, the filter traps soot particles while allowing clean exhaust gases to pass through. Under suitable operating temperatures, accumulated soot is continuously oxidized through passive regeneration, providing reliable particulate emissions control without external heating.
How does a GreenTRAP™ 300 work on a stationary diesel generator?
As exhaust gases flow through the wall-flow filter, particulate matter (PM) is captured inside the porous filter walls. During normal generator operation, the catalyst promotes passive regeneration by oxidizing the trapped soot whenever sufficient exhaust temperatures are available. This process continuously cleans the filter while maintaining low exhaust backpressure and reliable generator performance.
How does a Diesel Particulate Filter (DPF) work?
As diesel exhaust flows through the DPF, soot particles are captured within the porous filter walls while clean gases continue through the exhaust system. Under suitable operating conditions, the accumulated soot is oxidized through the regeneration process, restoring filter capacity and maintaining reliable generator performance.
What emissions does a GreenTRAP™ reduce?
A GreenTRAP™ or Diesel Particulate Filter (DPF) is designed primarily to reduce Particulate Matter (PM) and eliminate visible diesel smoke. Depending on the system configuration, it can also contribute to reductions in Carbon Monoxide (CO), Hydrocarbons (HC), and Hazardous Air Pollutants (HAPs), resulting in cleaner exhaust emissions.
Which generator applications are best suited for a GreenTRAP™?
GreenTRAP™ systems are widely used on stationary diesel generators operating in standby, prime power, and continuous-duty applications. Common installations include data centers, hospitals, utilities, manufacturing facilities, commercial buildings, and other critical power generation sites requiring particulate emissions control.
Does a GreenTRAP™ require regeneration?
Yes. A GreenTRAP™ requires regeneration to remove the soot collected during normal operation. Depending on the application, regeneration may occur naturally under normal exhaust temperatures or through an active regeneration process. Proper system sizing and operating conditions help ensure reliable long-term performance.
Can a GreenTRAP™ be installed on existing diesel generators?
Yes. The GreenTRAP™ system is available for both new generator installations and retrofit projects. Each system is engineered based on engine power, exhaust flow, operating temperature, available installation space, and project-specific emissions requirements.
Why choose a GreenTRAP™ for stationary diesel generators?
A GreenTRAP™ or Diesel Particulate Filter is one of the most effective technologies for controlling particulate emissions from stationary diesel generators. It significantly reduces diesel soot, improves air quality, supports regulatory compliance, and provides reliable long-term emissions control for standby, prime power, and continuous-duty generator applications.
