A preassembled skid-mounted RTO system offers a more efficient alternative to traditional field-built systems. Most regenerative thermal oxidizer (RTO) systems are assembled and installed directly in the field, which often requires extended installation timelines, large crews, and complex coordination. While this approach is common, it often requires extended installation timelines, larger field crews, and significant coordination between contractors.
As a result, paint finishing operations — including spray booths and oven dryers — must carefully manage downtime and installation complexity to maintain production efficiency.
To solve these challenges, TANN Corporation developed a fully skid-mounted, preassembled RTO system that we build, wire, and precommission in-house prior to delivery.
Designed for Paint Finishing Applications
This system was specifically engineered for paint finishing applications and is designed to manage emissions from both spray booth exhaust and oven dryer processes.
These emission sources require consistent airflow control, reliable thermal performance, and stable operation across varying production conditions. As a result, system design must account for fluctuations in process demand while maintaining efficiency and compliance.
Preassembled Skid-Mounted RTO System Design
Unlike traditional systems that are constructed on-site, this RTO is assembled on a structural skid within our facility.
Because we complete assembly in a controlled environment, we can maintain tighter quality standards and ensure better coordination between mechanical and structural components. In addition, this approach reduces variability during installation and helps streamline the overall project timeline.
Precomissioned and Electrically Integrated
In addition to mechanical assembly, we fully wire and precommission the system before shipment.
This process includes electrical panel integration, control system configuration, valve sequencing, airflow verification, and functional system testing.
By completing this work in-house, we verify system performance prior to delivery and significantly reduce the complexity of field startup. As a result, installation teams can focus on integration rather than troubleshooting.
Reduced Time and Installation Cost
Preassembled systems offer several advantages during installation. Because we complete the majority of assembly in-house, we can significantly reduce both installation time and overall project cost.
As a result, customers benefit from faster project timelines, fewer on-site resources, and a more predictable installation process.
Faster Installation
With major components already assembled, field installation time is significantly reduced.
Lower Labor Costs
Heavy assembly is completed in our facility, reducing crane usage and on-site labor demands.
Fewer Variables
Controlled shop assembly minimizes risks from weather, site constraints, and coordination challenges.
Customer Visibility and Confidence
Another key advantage of this approach is the ability for customers to inspect the system before shipment.
Because we complete assembly in-house, customers can review system quality, confirm configuration and layout, and gain confidence in overall system readiness prior to installation. As a result, they have greater visibility into the final product before it arrives on-site.
In contrast, traditional field-assembled systems rarely provide this level of transparency during the build process.
Controlled Path to Performance
While field assembly remains common across the industry, preassembled and precommissioned RTO systems provide a more controlled and efficient path to installation and startup.
Because we complete assembly, integration, and testing in-house, we can identify and address potential issues before the system reaches the job site. This approach not only improves consistency during installation, but also reduces the risk of delays, rework, and unexpected challenges in the field.
Ultimately, system performance is not determined by design alone — it depends on how well that design is executed, integrated, and commissioned. By controlling these critical steps, we help ensure that each system performs as intended from day one. A preassembled skid-mounted RTO system provides a more controlled and reliable approach compared to traditional field-assembled systems.
