Regenerative Thermal Oxidizer

With RTOs, timely inspections and maintenance are essential to ensure high reliability, cost-effective performance, and lowest cost of ownership.

RTO Services & Solutions

Our experienced field team is fully trained and equipped to service, repair, and/or upgrade all types of Regenerative Thermal Oxidizers, Concentrators, and their control systems. No one knows more about RTOs or offers a more comprehensive range of RTO services.

We provide detailed, on-site, internal and external inspections of all makes, models, and types of RTOs. Our detailed reports feature an executive summary of the general condition of the system that highlights critical action items and recommended maintenance actions ranked in order of importance and backed up by photographic documentation. Enjoy flexible scheduling and special focus on any specific operational concerns. Our Inspections
Call us today for around-the-clock, nationwide emergency service on your RTO. Our technicians are prepared to answer your emergency call-out and get your facility back online as soon as possible. Not sure if it’s an emergency? Contact us and we can help you determine the severity of your issue and the best course of action.
From bake-outs to turnkey media replacements, we offer a full suite of ceramic media services. Plugging and fouling of media will degrade system performance to the point where a bake-out or turnkey media replacement is required. Sometimes, there’s a mismatch between the type of media currently in the unit and what might be optimal. As an unbiased third party (unlike an OEM), we can offer you a qualified judgment as to the benefits and drawbacks of different types of media. Our Ceramic Media Services
At the heart of an oxidizer is its control system, which oversees key operations such as poppet valve switching, temperature, retention times, and much more. If your RTO’s control system is not set up properly – or if it has been improperly adjusted to correct for another issue – it can cause reliability, safety, and compliance issues. The more robust your control system, the more efficient and reliable your RTO system’s performance will be. The right control system can also be key to troubleshooting the system so repairs can often be made in minutes, not hours. Control System Services
If these high-cycle valves do not seal properly, the RTO will not maintain proper destruction and removal efficiencies. We have extensive experience repairing and replacing all types of RTO diverter valves to guarantee that your RTO is operating properly and that you remain in compliance..

Gaps or deterioration in RTO insulation can lead to “hot spots” on the RTO shell, posing safety risks and potentially leading to metal degradation and air leaks. Our thermal imaging cameras translate thermal energy (heat) into visible light to help determine the condition of key components like insulation or refractory in an oxidizer, or the machine health of fans, pumps, and motors. Repairing hot spots reduces auxiliary fuel costs, prevents more costly repairs in the future, and prevents downtime.
We offer comprehensive ductwork solutions, including full duct replacement and remediation of flow restrictions. We assess the root causes—such as corrosion, vibration fatigue, or insulation degradation—and, when needed, redesign and fabricate new duct systems. Our turnkey service includes custom fabrication, installation, commissioning. And in cases of pressure drop or reduced throughput, we clear or replace flow restricted sections to restore optimal fan performance and ensure reliable RTO efficiency.
We offer a full range of Concentrator services including inspection, troubleshooting, component repair or replacement, and system optimization. Our technicians frequently address clogged or degraded concentrator beds and flow restrictions to restore full processing efficiency. We have extensive experience with Zeolite concentrators and deliver cost effective, long lasting solutions that enhance reliability, reduce downtime, and maintain regulatory compliance.
How much fuel does your system consume? Could you save by optimizing air-to-fuel ratios or switching to another type of burner? Burner technology has improved greatly over the years, increasing not just efficiency but also safety. An unbiased evaluation of your burner and gas train offers many benefits, including peace of mind. Burner and Gas Train Services.
Do you have adequate spare parts on hand, especially for high-wear, high-failure system components like thermocouples? We can provide you with the right spare parts package for your system.

Ceramic Media Services

The condition of an RTO’s ceramic media is crucial to system performance. We offer a complete range of ceramic media services, from media cleanings and bake-outs to turnkey media replacements.

What Sets Our RTO Services Apart?

Our field technicians work on all makes and models of RTOs (not just a specific manufacturer’s) and offer unbiased, customized recommendations. What’s more, they’re trained to go beyond presenting mechanical problems to troubleshoot underlying issues common to certain RTO systems and industrial applications. As a result, you receive the optimal solution for your unique oxidizer system, application, and pain points – so your RTO operates more reliably and cost-effectively.

As an independent service company (not an Original Equipment Manufacturer, or “OEM”), we provide:

  • Customized, Flexible Service
  • Quick Response Times
  • Unbiased Recommendations
  • Cost-Effective, Long-Lasting Solutions
  • Comprehensive Solutions tailored to your specific RTO and facility

Learn How an RTO Works

Regenerative Thermal Oxidizers are air pollution control systems designed to destroy volatile organic compounds (VOCs) and hazardous air pollutants (HAPs) from industrial exhaust streams. Known for high thermal recovery efficiencies, they can greatly reduce fuel consumption and operating costs compared to other emission control technologies.

Regenerative Thermal Oxidizer and Concentrator

Is an OEM the Best Choice for RTO Aftermarket Services?

Relying on the original OEM to service your RTO can make sense during the warranty period, but what about after that? When you hire PolSys Services as a third-party service provider you enjoy cost efficiency, unbiased recommendations, faster response times, broader technical expertise, and more value-added service. You get the biggest bang for every “service” buck!
