Inspection and Replacement Planning for SCR, DPF, and Oxicats
Extend System Life. Maintain Compliance. Avoid Downtime.
Your emissions control system works hard to keep your operations clean and compliant—but like any high-performance equipment, it requires regular inspection and maintenance to continue performing at its best.
At AERINOX, we provide clear, application-specific inspection and replacement schedules for all critical emissions system elements—including SCR catalysts, Diesel Particulate Filters (DPFs), and Oxidation Catalysts (Oxicats)—so you can stay ahead of performance issues and regulatory risks.
Why Routine Inspections Matter
Over time, catalyst elements and filtration media can degrade or become fouled by soot, ash, oil, or chemical contamination. Without regular checks and timely replacement, you risk:
- Reduced NOx reduction or PM filtration efficiency
- Non-compliance with emissions standards or Tier 4 limits
- Higher backpressure, engine inefficiencies, or system faults
- Unplanned downtime and costly emergency repairs
That’s why AERINOX provides proactive maintenance planning based on engine duty cycle, fuel type, and operating environment—ensuring optimal performance and maximum lifespan of your system.
Recommended Inspection & Replacement Intervals
- Inspection: Every 6,000–8,000 engine hours
- Replacement: Typically every 16,000–20,000 hours, depending on fuel quality and exhaust conditions
- Key Signs of Wear: NOx breakthrough, uneven temperature profiles, increased ammonia slip
Diesel Particulate Filters (DPFs)
- Continuous Monitoring of pressure drop through PLC program
Oxidation Catalysts (Oxicats)
- Inspection: Every 6,000–8,000 hours
- Replacement: Often effective up to 20,000+ hours with proper fuel/oil control
- Key Signs of Wear: Elevated CO/HC emissions
Exact intervals may vary depending on engine type, duty cycle, fuel quality, and system configuration. AERINOX provides customized maintenance guidance for every installation.
