SYSTEM OVERVIEW
How the Oxidation Catalyst Works
Exhaust passes through a metallic cordierite substrate coated with a precious metal catalyst. As exhaust contacts the catalytic surface, CO and HC and oxidized into CO2 and water vapor. No reagents, no moving parts, no maintenance required.
Maintenance-Free
No regeneration or scheduled catalyst maintenance required
Low Backpressure
Maintains engine performance with minimal exhaust restriction
Direct-Fit Design
Available in universal and OEM replacement configurations
Corrosion Resistant
Constructed from stainless and aluminized steel
Sound Attenuation
Matches or exceeds OEM muffler acoustic performance
FREQUENTLY ASKED QUESTIONS
Oxidation Catalyst (OC) system Common Questions
Find answers to the most common questions about M-Series Oxidation Catalyst (OC) systems, stationary diesel generator emissions control, EPA compliance, and oxidation catalyst technology for power generation.
What is an Oxidation Catalyst (OC)?
An Oxidation Catalyst (OC) is an exhaust aftertreatment device designed to reduce Carbon Monoxide (CO), Hydrocarbons (HC), and Hazardous Air Pollutants (HAPs) from stationary diesel generators. Using a high-efficiency oxidation catalyst, it converts harmful emissions into carbon dioxide (CO₂) and water vapor (H₂O) while maintaining reliable generator performance.
How does an Oxidation Catalyst work?
As exhaust passes through the oxidation catalyst, precious metal coatings promote chemical oxidation reactions. Carbon Monoxide (CO) and unburned Hydrocarbons (HC) are converted into less harmful gases, improving exhaust quality without affecting engine operation.
Is a OC suitable for stationary diesel generators?
Yes. Oxidation Catalysts are widely used on stationary diesel generators for standby, prime power, and continuous-duty applications where reliable reduction of CO, HC, and HAPs is required.
Does an OC require regeneration?
No. Unlike Diesel Particulate Filters (DPFs), Oxidation Catalysts do not store soot and therefore require no active or passive regeneration, making them a simple and maintenance-free emissions control solution.
Does an OC increase exhaust backpressure?
No. Modern Oxidation Catalysts are designed with low-restriction substrates that minimize exhaust backpressure while maintaining engine performance and fuel efficiency.
Can an OC replace a diesel generator muffler?
Yes. Many Oxidation Catalyst systems are available as direct-fit catalytic mufflers or universal configurations, allowing easy integration while maintaining excellent sound attenuation.
Is an OC compatible with OEM and retrofit generators?
Yes. OC systems can be installed on both new generator packages and existing diesel generators without major engine modifications, making them suitable for OEM and retrofit applications.
Does an OC require engine recalibration?
No. Oxidation Catalysts operate independently of the engine control system and normally do not require engine recalibration or ECU remapping.
What are the benefits of a metallic oxidation catalyst?
Metallic oxidation catalysts provide excellent thermal durability, low backpressure, rapid heat transfer, and long service life, making them ideal for stationary diesel generator applications.
What maintenance does an OC require?
Oxidation Catalysts are designed for maintenance-free operation. With no soot storage or regeneration cycle, routine maintenance is generally limited to periodic visual inspection during scheduled generator servicing.
Why choose an Oxidation Catalyst for power generation?
An Oxidation Catalyst provides a simple, reliable, and cost-effective solution for reducing Carbon Monoxide (CO), Hydrocarbons (HC), and Hazardous Air Pollutants (HAPs) from stationary diesel generators. It offers low backpressure, maintenance-free operation, and straightforward integration without affecting generator reliability.
