What Are the Advantages of Using a Regenerative Thermal Oxidizer for Your Manufacturing Plants?

The benefits of a regenerative thermal oxidizer system are mostly related to the lower capital and operating costs for processes with high airflow and low VOC levels.

Besides that, thermal efficiency technology is used in regenerative thermal oxidizers, and this seemingly basic airflow design provides several advantages that make them more energy-efficient than conventional oxidizers. These can be summed up in five main points:

Excellent Rates of VOC and HAP Decomposition

VOC destruction rates are high in a regenerative thermal oxidizer. As a result, they only create heat, water, and carbon dioxide as waste. They're also incredibly dependable, and they can be developed and scaled to expand along with your business.


RTOs, as previously said, have low operational costs. This is because the heat created during the VOC/HAP destruction process is reused. Before entering the oxidation chamber, polluted gas is preheated, lowering the amount of energy required to reach high temperatures.

Specific Circumstances Are Required

A thermal oxidizer is ideal for plants that produce clean VOCs and have large volume airflows. Some outstanding choices for these systems include the manufacturing of paint, heat-set printing and flexographic printing, coating and laminating of webs, and pharmaceutical manufacturing services.

Simplistic Design

RTOs are not only incredibly energy efficient but also extremely practical. They have a simple design that requires less maintenance and repairs while still providing excellent performance.

Exceptional Thermal Efficiency

RTOs are so cost-effective because, under the correct conditions, they can achieve up to 97 percent heat recovery. Because only a small amount of fuel is required, they have lower operating costs than other oxidizer designs while still eliminating a high percentage of HAPs and other pollutants.

The Design of a Regenerative Thermal Oxidizer

A regenerative thermal oxidizer can help you save money in the long run by lowering your running costs. Let’s see how that comes into effect because of its innovative design.

Aspects Of Design That Influence Operating Costs

Temperature: The temperature of the process exhaust is used to evaluate operating expenses and the need for ducting insulation.

Types And Quantities of Air Pollutants: The type and concentration of air pollutants, as well as the amount and solvent type, have an impact on predicted operating costs.

Electricity And Fuel Costs: Estimated running costs are based on both electricity and gasoline costs.

Thermal Efficiency: This design component is crucial because it is one of the key variables impacting running expenses. A thermal oxidizer has low thermal efficiency and operates at high temperatures, whereas RTOs have a higher thermal efficiency but operate at lower temperatures. (An RTO loses only 5% of its energy input during operation, whereas a thermal oxidizer loses 30% of its energy input.)

Maintenance: Because some oxidizers have a more sophisticated design, they require more maintenance than others.

Aspects Of Design That Influence Capital Costs

The unique airflow design of Regenerative Thermal Oxidizers (RTOs) is responsible for their high energy efficiency. They are efficient, reliable, and always more fuel-efficient than any other type of oxidizer due to their high VOC destruction rate.

A thermal oxidizer and regenerative thermal oxidizer is the most popular VOC abatement technology because of its ability to lower system running costs and energy usage. By repurposing the thermal energy generated during operation, the system can achieve this.

Each Emission Point's Exhaust Rate and Temperature: Exhaust rates and temperatures are vital to keeping in mind because they are used to size the unit, ductwork, and dampers.

Expected Growth: Installing a system that can handle additional capacity today is usually more cost-effective than installing a second system later.

What Are the Benefits of Using a Regenerative Thermal Oxidizer Instead of a Thermal Oxidizer?

  • It Can Be Used in A Variety of Industries. Most factories with high exhaust air volumes and low pollution concentrations can benefit from regenerative thermal oxidizers.
  • Its Heat Recovery Mechanisms Are Ideal. Because they are ideal for heat recovery systems, regenerative thermal oxidizers offer minimal running costs. Many heat transfer media are used in RTOs to heat polluting air before it reaches the combustion chamber and cool clean air before it is discharged into the atmosphere.

Other Benefits Include:

  • A regenerative thermal oxidizer can achieve a thermal efficiency of up to 97%.
  • VOC concentrations ranging from 0% to 15% of the LEL were measured.
  • Low particulate matter in the process gas or after VOC combustion.
  • Process gas temperatures of up to 500 degrees Fahrenheit.
