High-Performance Components for Emission Control
Reliable. Compliant. Engineered for Performance.
At AERINOX, our expertise doesn’t stop at complete systems—we also provide the individual components that power high-performing, compliant emission control solutions. Whether you’re building a system from the ground up or replacing parts in the field, we supply the components you need for NOx reduction, particulate matter control, and overall emissions compliance.
With decades of real-world experience in stationary diesel and natural gas engine applications, our components are backed by industry-leading engineering, service, and support.
What We Offer: High-Performance Components for Emissions Control
Our component offerings are designed to support engines across a variety of markets—including data centers, agriculture, manufacturing, and power generation—and are fully compatible with Tier 4, EPA, and local emissions regulations.
SCR System Components
We provide a full range of parts that make up an effective Selective Catalytic Reduction (SCR) system for NOx reduction in large stationary engines:
- SCR Catalysts – Modular and custom-sized for optimal NOx conversion efficiency
- Urea Dosing Modules – Reliable, precision injection systems
- Mixing Elements – Ensure even distribution of ammonia and exhaust gases
- System Sensors and PLC Controls – For automatic operation and compliance tracking
- Ammonia Slip Catalysts (ASC) – Prevent excess ammonia emissions downstream
Diesel Particulate Filters (DPF)
Our DPFs are engineered to trap and oxidize particulate matter (PM) from diesel exhaust, helping customers meet Clean Air Act requirements while maintaining optimal engine performance. These are ideal for diesel engines operating under Tier 4 Final or similar regulations or seeking retrofit solutions.
Oxidation Catalysts (Oxicat)
Used in combination with SCR or DPF systems, our oxidation catalysts significantly reduce carbon monoxide (CO), hydrocarbons (HC), and can assist with passive regeneration of DPFs. These components are built for durability and low maintenance, whether in backup applications or continuous-duty environments.
System Controls & Integration
Every emissions system we design and build is supported by custom-engineered control panels, PLC-based automation, and remote monitoring options. This allows for seamless integration, optimized dosing control, and full compliance verification.
Why Choose AERINOX Components?
From the beginning of every project, we work closely with you to:
