What Is a Regenerative Thermal Oxidizer and What Are Its Advantages and Disadvantages?

RTO generation has been evolved for big volumes and occasional VOC attention air pollutants applications. The quality instance is spray sales space exhaust wherein the quantity of exhaust is excessive and VOC attention could be very low. RTO manufacturers agree that the Regenerative Thermal Oxidizer generation is primarily based totally on the usage of ceramic media as warmness exchangers and switching values.


  • High thermal efficiency
  • Very low working cost
  • Extremely rugged
  • No metal, no trouble of expansion
  • Simple System, Simple Design
  • Easy entry for all of the most important additives for renovation and repair
  • Life span of 20+ years with the right renovation


  • High pressure drops through the media
  • High electric electricity cost
  • Requires large actual estate
  • Media desires changing every 5 -6 years on average, however may also get an extended life with the right renovation.
  • Heavy put on and tear on transferring parts - Dampers/actuator are excessive renovation and desires changing every three-four years (with right renovation lifespans may be enhanced)

What Are the Applications of a Regenerative Thermal Oxidizer?

The regenerative thermal oxidizer (RTO) is a VOC emission control system designed for low average VOC concentrations in process applications.

Paint spray booths, paint, and coatings manufacture, amine treater off gas, ethanol facilities, and chemical manufacturing processes are all examples of pollution control uses where regenerative thermal oxidizer suppliers provide their services.

What Is a Recuperative Thermal Oxidizer and How Does It Work?

For process applications with lower flow rates or VOC concentrations exceeding 10% LEL, a recuperative thermal oxidizer is an optimum option. Amine treater off gas, cellulosic ethanol plants, calciner, and spray dryer exhaust, and chemical manufacturing processes are all examples of applications for a recuperative thermal oxidizer.

The recuperative thermal oxidizer heat exchanger is designed to recover up to 75% of available thermal energy for reuse in preheating the process airstream.

A recuperative thermal oxidizer's standard VOC destruction efficiency is 99 percent or higher. Each oxidizer is tailored to the needs of a particular application. The capacities range from 200 to 10,000 SCFM.

The oxidizer body is a sturdy item preassembled by talented and experienced RTO manufacturers that includes a shell and tube heat exchanger combustion chamber, burner, and light ceramic fiber insulation on the inside.

What Are the Features of a Recuperative Thermal Oxidizer?

  • Efficacy of VOC destruction is at least 99 percent.
  • From 40% to 75% thermal efficiency, variable heat exchanger designs are available.
  • Ceramic fiber reactor chamber with high-density insulation
  • Design that is standardized
  • Maintenance is simple.

What Are the Applications of a Recuperative Thermal Oxidizer?

VOC abatement with Recuperative Thermal Oxidizers is applicable in a variety of process applications, including those with particles, greater VOC concentrations, or even operations where a considerable amount of heat energy is required elsewhere in your facility. Many energy-saving alternatives are available in the designs brought to you by some of the best thermal oxidizer suppliers listed below in the article, including the use of warmed combustion air, a secondary heat exchanger, and advanced burner controls.

Applications and Industries for Recuperative Thermal Oxidizers

These systems combine a heat exchanger and a combustion chamber to manage a variety of process flow rates and VOC concentrations. To save running costs, the heat exchanger is employed to pre-heat the VOC-laden air before it enters the combustion chamber. The following are examples of Thermal Recuperative Oxidizers:

  • Perfect for moderate VOC concentrations.
  • Secondary Heat Recovery Appropriate.
  • Typically, a destruction efficiency of more than 99 percent can be achieved.
  • Thermal efficiency of up to 80% is possible.

Corn Processing Facilities, Industrial Processes, Fiberglass & Composite Industries, Printing, Beverage Can Manufacturing, Process Coating and Laminating, Chemical Processes, Polystyrene Foam Manufacturing, and Metal Finishing Operations are some of the most prevalent industrial applications.

The Final Verdict: Regenerative Thermal Oxidizer Vs. Recuperative Thermal Oxidizer

For most industrial air emission control applications, several regenerative thermal oxidizer suppliers concur that RTOs are by far the oxidizer of choice. RTOs have the highest VOC destruction rates while having the lowest operating costs. When compared to other thermal oxidizer technologies, they also offer the longest life and maximum reliability.

A thermal recuperative oxidizer, on the other hand, would be the superior choice for applications requiring 99.99 percent VOC elimination. A thermal recuperative oxidizer can sometimes challenge RTOs in energy efficiency when heat recovery can be used to heat a process (i.e., an oven) running at 300 F or higher.
