RTO performance issues can develop even in well-designed systems. In many cases, performance does not decline because of a single failure. Instead, it is reduced over time as operating conditions change, maintenance is delayed, or hidden mechanical issues go unnoticed. Below are five common RTO performance issues that can impact system efficiency and long-term performance.
1. Process Changes Can Create Major RTO Performance Issues
Many RTO performance issues do not start with a design flaw. Instead, they develop when the process changes and the system continues to operate under new conditions. A system that performed well at startup may struggle years later because the facility no longer runs the same way.
Production lines often evolve over time. Solvent loads increase, coatings change, and throughput expands. As those changes happen, the original operating assumptions may no longer match reality. When that gap grows, efficiency and compliance can both be affected.
Common process changes include:
- Higher VOC loading than the system was originally designed to handle
- Changes in solvents, coatings, or raw materials
- Increased production rates that raise exhaust volume
- Operating conditions that no longer match the original design basis
In other words, RTO systems are designed for a moment in time, but most facilities continue to change. Because of that, regular system reviews should be considered if long-term performance is expected.
How TANN Helps Prevent Long-Term Performance Problems
At TANN Corporation, we understand that manufacturing processes rarely stay the same over the life of an RTO system. Production demands increase, coatings change, and airflow requirements evolve over time. Because of that, we evaluate more than just current operating conditions during the design phase.
Our engineering team works closely with customers to understand potential future expansion, process variability, and long-term operational goals before the system is designed. In many applications, systems can be configured with additional capacity considerations to help accommodate future growth and changing VOC loading conditions.
We also provide ongoing technical support, system evaluations, and performance reviews to help facilities identify operational changes before they begin impacting efficiency, fuel consumption, or compliance performance.
The goal is not simply to make the system work on day one. The goal is to help the system continue performing reliably for years as the facility evolves.
2. Temperature and Pressure Drift
You can have the right system in place and still experience RTO performance issues. In many cases, small changes in temperature and pressure are enough to reduce overall system effectiveness, even when operations appear normal.
These changes are often gradual. Sensors may drift, operating conditions may be adjusted slightly, and routine calibration may be delayed. As a result, the system can slowly move away from optimal performance without being immediately noticed.
Common causes of temperature and pressure drift include:
- Sensor drift due to lack of calibration
- Incremental operator adjustments over time
- Inconsistent monitoring or data tracking
- Delayed maintenance on key components
Because these issues develop slowly, they are often overlooked until performance has already declined. For that reason, consistent monitoring and maintenance play a critical role in maintaining efficiency.
How TANN Supports Long-Term System Performance
Temperature and pressure drift often develop slowly over time, which makes these issues difficult to identify without consistent monitoring and system evaluation. At TANN Corporation, our service and technical support teams help facilities identify small operational changes before they become larger performance or compliance problems.
Our technical services include system inspections, troubleshooting support, calibration verification, thermal imaging, and preventative maintenance evaluations designed to help maintain stable operating conditions throughout the life of the system.
Because we design, build, and support our systems in-house, our team understands how the equipment is intended to operate and what performance indicators should be monitored over time. That experience helps facilities maintain consistent thermal efficiency, reduce unnecessary fuel consumption, and avoid unplanned downtime caused by gradual performance decline.
Consistent monitoring and preventative maintenance are some of the most effective ways to protect long-term RTO performance.
3. Leaky Dampers (A Hidden Efficiency Killer)
One of the most common RTO performance issues is also one of the least visible—a leaking damper. In many systems, especially those using butterfly dampers, even a small amount of leakage can create a measurable impact on overall performance.
When a damper does not seal properly, untreated air can bypass the combustion chamber. As a result, the system may appear to be running normally, while destruction efficiency is quietly reduced.
Common causes of damper leakage include:
- Wear over time on sealing surfaces
- Improper alignment or installation
- Thermal expansion affecting fit and seal
- Mechanical degradation that is not immediately visible
Because these issues develop gradually, they are often difficult to detect without inspection or performance testing. In many cases, the impact is only noticed after efficiency has already declined.
How TANN Addresses Damper Performance and System Reliability
Damper leakage is one of the most difficult RTO performance issues to identify because the system can continue operating while efficiency slowly declines in the background. At TANN Corporation, long-term sealing performance and valve reliability are important considerations during both system design and ongoing service support.
Our engineering team evaluates airflow patterns, thermal expansion, operating temperatures, and maintenance accessibility when designing system configurations. Proper valve and damper performance play a major role in maintaining destruction efficiency and minimizing unnecessary fuel consumption over time.
In addition to system design, our service team provides inspections, troubleshooting support, and maintenance evaluations that help identify wear, alignment issues, and sealing problems before they create larger operational or compliance concerns.
Small leakage problems may not be immediately visible, but over time they can have a significant impact on overall RTO performance and operating efficiency.
4. Undersized Systems (A Costly Long-Term Issue)
In some cases, RTO performance issues are not caused by maintenance or operation. Instead, they begin at the design stage when a system is sized too tightly for real-world conditions.
To reduce upfront cost, systems may be designed based on ideal assumptions. However, actual operating conditions rarely stay within those limits. As production increases or emissions fluctuate, the system can become overloaded.
Common causes of undersized systems include:
- Optimistic VOC or airflow estimates during system design
- Limited allowance for future production growth
- Failure to account for variability in operating conditions
- Designing too close to maximum capacity without a safety margin
When this happens, the system is not necessarily failing—it is simply being asked to do more than it was designed to handle. As a result, efficiency may drop and compliance margins can become tighter.
How TANN Designs for Long-Term Operating Conditions
At TANN Corporation, system sizing is based on more than ideal operating conditions or short-term production targets. Our engineering team evaluates airflow variability, VOC loading, future production considerations, and real-world operating conditions to help ensure the system can perform reliably over the long term.
In many applications, designing too close to maximum capacity may reduce upfront cost initially, but it can create efficiency, fuel consumption, and compliance challenges later as facility demands increase. Because of that, we work closely with customers to understand both current operating requirements and potential future expansion before finalizing a system design.
Our goal is not simply to size a system for startup conditions. The goal is to provide a solution that can continue operating efficiently as the facility evolves over time.
Proper system sizing is one of the most important factors in maintaining long-term RTO performance, efficiency, and operational flexibility.
5. Ductwork and Airflow Restrictions (Often Overlooked)
Not all RTO performance issues originate within the RTO itself. In many cases, system performance is affected by conditions upstream—particularly within the ductwork.
Over time, duct systems can accumulate material that restricts airflow. As buildup increases, the system may struggle to maintain proper flow balance, which can impact overall efficiency.
Common causes of airflow restriction include:
- Particulate buildup inside ductwork
- Condensable materials collecting over time
- Residue from coatings or process byproducts
- Lack of routine duct inspection and cleaning
Because these issues occur outside of the RTO, they are often overlooked during troubleshooting. However, airflow is critical to system performance, and even minor restrictions can create noticeable impacts.
How TANN Evaluates Complete System Airflow Performance
At TANN Corporation, we understand that long-term RTO performance depends on more than the oxidizer alone. Airflow balance throughout the entire system—including ductwork, fans, and upstream process conditions—plays a major role in overall efficiency and operational stability.
Our service and engineering teams help facilities identify airflow restrictions, buildup issues, and process conditions that may be limiting system performance over time. In many cases, these problems develop gradually and remain unnoticed until fuel consumption increases, pressure changes occur, or system efficiency begins to decline.
Through system evaluations, troubleshooting support, and preventative maintenance inspections, we help customers identify airflow-related issues before they create larger operational or compliance concerns.
Maintaining proper airflow throughout the entire system is critical to consistent RTO performance, thermal efficiency, and long-term reliability.
Address RTO Performance Issues Before They Impact Your Operation
RTO performance issues are often the result of small changes that develop over time. In many cases, they go unnoticed until efficiency drops or compliance becomes a concern. Identifying and addressing these issues early can help improve system performance and reduce long-term operating costs.
