Regenerative Thermal Oxidizers for Can Manufacturing
A regenerative thermal oxidizer for can manufacturing has to perform in an industry where energy efficiency and sustainability reporting carry as much weight as emissions compliance. TANN designs RTO systems for this application, and also builds regenerative catalytic and electric catalytic oxidizers where a lower-temperature technology is the better fit for the line.
Why Can Manufacturing Needs the Right Regenerative Thermal Oxidizer
Coating and curing lines in can manufacturing run continuously, and energy cost is a direct line item facilities are measured against. A regenerative thermal oxidizer for can manufacturing has to deliver high destruction efficiency while holding up its end of the plant's overall energy balance, not just clean the exhaust stream and stop there.
That's also why this is one of the industries where TANN's broader oxidizer capability matters most. Alongside standard RTO systems, TANN builds regenerative catalytic oxidizers and electric catalytic oxidizers, which destroy VOCs at lower operating temperatures and can make waste heat available for recovery. Which technology fits best depends on the specific line, the exhaust characteristics, and how the facility wants to balance capital cost against energy recovery.
The other defining condition in this application is cold-source exhaust. When the temperature of a cold, unheated exhaust stream drops, VOC-bearing residue that was carried as vapor condenses out and hardens on surfaces, a condition generally referred to as coking. Concentrators are frequently paired with these cold-source streams, regardless of which oxidizer technology is downstream, to manage volume and load before the exhaust reaches the unit.
What Defines a Can Manufacturing Oxidizer Application
A regenerative thermal oxidizer for can manufacturing, or the catalytic alternatives built alongside it, has to satisfy several conditions at once:
- High destruction efficiency, typically at the top end of what regulators expect from any oxidizer technology
- Energy recovery and electrification as first-order design priorities, not afterthoughts
- Waste heat recovery potential, since lower operating catalytic technologies can make heat available for reuse
- Cold-source exhaust handling, often paired with a concentrator to manage volume and reduce coking on ductwork and internal surfaces
Built for What This Application Demands
TANN engineers and fabricates oxidizer systems in-house at our Kaukauna, Wisconsin facility. Whether the right fit is a regenerative thermal oxidizer for can manufacturing or a catalytic alternative, the design decisions below are what hold up in this application.
Regenerative Thermal Oxidizer Systems
For lines where high-volume airflow and robust heat recovery are the priority, TANN's standard RTO construction, including durable ceramic media, horizontal poppet valve design, and clean fan design, provides the reliability this continuously operating industry needs.
Regenerative and Electric Catalytic Options
Where lower operating temperature and waste heat recovery potential matter more, TANN also builds regenerative catalytic and electric catalytic oxidizers. These technologies destroy VOCs at meaningfully lower temperatures than a thermal-only design, which is a common priority in can manufacturing's energy and sustainability goals.
Concentrators for Cold-Source Exhaust
Cold-source exhaust streams are prone to coking as residue condenses and hardens when the stream cools. Pairing a concentrator with the oxidizer, whichever technology is selected, reduces the volume the unit has to handle and helps manage where and how that residue accumulates in the system.
In can manufacturing, the right answer isn't always the same oxidizer technology twice. TANN's experience across regenerative thermal, regenerative catalytic, and electric catalytic systems means the technology gets chosen to fit the line, not the other way around.
What Can Manufacturing Oxidizers Are Up Against
Understanding the pressures on a regenerative thermal oxidizer for can manufacturing, or a catalytic system in the same role, helps facilities evaluate whether an existing setup is actually built for this application's energy and maintenance demands.
Coking on Cold-Source Exhaust Surfaces
When a cold, unheated exhaust stream drops in temperature, residual VOCs condense and harden on ductwork and internal surfaces. Left unaddressed, this buildup restricts flow and adds maintenance burden, particularly upstream of concentrators.
Media and Catalyst Fouling
RTO ceramic media and catalytic media both lose performance over time, though for different reasons: media blinding from particulate in RTOs, and thermal aging or catalyst poisoning in catalytic systems. Either shows up as declining destruction efficiency and rising temperatures needed to maintain performance.
Energy and Sustainability Reporting Pressure
Facilities in this industry are commonly evaluated on energy use and sustainability metrics, not just emissions compliance. An oxidizer that isn't well matched to the line's energy profile becomes a visible line item in those reports.
Waste Heat Recovery Considerations
Recovering waste heat from the oxidizer adds another system to size and control alongside the unit itself. Whether that's worth pursuing depends on the specific line, and it's a decision worth evaluating case by case rather than assuming it fits every application.
Concentrator and Oxidizer Balance
Concentrators reduce the exhaust volume reaching the oxidizer, but the two have to be sized and controlled as a matched system. A mismatch between concentrator output and oxidizer capacity shows up as pressure drop issues or inconsistent destruction efficiency.
Combustion and Controls Drift
As with any continuously operating oxidizer, burner components, sensors, and control parameters can drift over time. Temperature deviations affect destruction efficiency, fuel or electric consumption, and compliance reporting regardless of the process being served.
TANN Supports Your System for the Long Term
A regenerative thermal oxidizer for can manufacturing, or its catalytic counterpart, is a long-term investment tied closely to the rest of the production line's energy performance. TANN stays involved from initial engineering through the full operating life of the system, across every oxidizer technology we build.

TANN's service team can support cleanout of cold-source ductwork prone to coking, along with concentrator maintenance, coordinated around your production schedule.
24/7 Emergency Response
TANN's service team is available around the clock. When an unplanned issue affects your emissions control system, our team can troubleshoot remotely and mobilize qualified technicians to your facility when you need them most.
Warning Signs a Can Manufacturing Oxidizer Needs Attention
In this application, energy performance issues often show up before an outright compliance problem does. Catching them early protects both your emissions record and your energy numbers, whether the system on site is a regenerative thermal oxidizer or a catalytic design.
Performance Indicators
- Rising bed or catalyst temperatures needed to maintain the same destruction efficiency
- Increasing fuel or electric consumption without a corresponding change in production volume
- Reduced destruction efficiency or approaching permit compliance thresholds
- A noticeable drop in waste heat recovery output, where a recovery system is in place
Operational Observations
- Visible coking or residue buildup on cold-source ductwork ahead of the concentrator
- Increased frequency of alarms, temperature faults, or controls trips
- Concentrator performance that no longer matches oxidizer capacity as it once did
- Any system that has not had a documented inspection in more than 12 months
