Regenerative Thermal Oxidizer(RTO)

One of the technologies air pollution control systems has been recognized as having the highest efficiency. That is the Regenerative thermal oxidizer system (RTO).

Prolific group is cooperating with a partner, KIYEON E&C. has developed and applied a regenerative heat/catalytic oxidation system that can completely reduce VOCs, HAPs, Odors, and CO with almost no loss of heat energy by designing to abate VOCs, HAPs, Odors, and CO in off gas through one system using heat storage materials (One Can-Tank).

Rotary RTO Regenerative Thermal Oxidizer (One Can – Tank)

One can -Tank rotary RTO has reached the world’s advanced level of product technology, with high-end quality to the market users more high-end choice, to help more enterprises to successfully launch on the road to green development, to achieve economic development and environmental protection and can grow together with the world in a sustainable way.

Our valve type RTO completely solves the chronic gas leak problem by converting the leakage problem of the rotating body, which has been pointed out as a problem of the existing rotating rotary type, to the valve method, and prevents failure due to deformation of the rotating body and an integrated structure. It is a newly developed product that has dramatically improved maintenance difficulties, which is a weakness


  1. Top quality Part – selection of super wear-resistant anti-aging fluoro silicone sealing materials
  2. Excellent insulation and energy saving – reduce convection heat dissipation, energy saving effect increased
  3. Operation safety – top safety components, safety control software with artificial intelligence learning judgment and failure prediction ability
  4. Convenient network interaction – Real-time cloud monitoring, friendly UX network data interaction function
  5. Best design for production line – tailor-made pattern so that appearance is suitable for different areas and production line

What is a Regenerative Thermal Oxidizer?

A regenerative thermal oxide (RTO) is a combustion device that controls volatile organic compounds (VOCs), hazardous air pollutants (HAPs), and odors by converting emissions into (destructive) emissions and by using heat to convert emissions into CO2 and H2O and then release them into the atmosphere. RTO can achieve a thermal efficiency of up to 97% and destruction efficiency of over 99%.

RTO is considered one of the most advanced thermal oxidation systems in the world. Compared to other thermal oxidizers, The RTO has a thermal efficiency of up to 97% because it has the systems for recovery energy to heat and destruction efficiency may exceed 99%, which will give you the highest removal rate at the lower operating costs, and the lowest life cycle cost.

How Does a Regenerative Thermal Oxidizer Work?

  1. Process exhaust air (with VOCs) enters the RTO and is directed into the ceramic heat exchange media where it is preheated.
  2. Pre-heated air enters the combustion chamber where it is heated to the set-point temperature where oxidation of the VOCs are completed.
  3. Hot treated clean air is cooled as it passes through the heat exchange media and is exhausted from the stack into the atmosphere.
  4. the process of airflow reverses direction as the rotary valves switches positions, allowing the heat captured in the ceramic media from the exiting clean air stream to heat the incoming process air. It is this regeneration of the ceramic heat exchanger media, with its high heat capacity, that enables a regenerative thermal oxidizer to deliver greater than 95% thermal efficiency.

This is why RTO (regenerative thermal oxidizers) have high fuel efficiency and low operating costs, making them an ideal VOC reduction system.

Choice of RTO Regenerative Thermal Oxidizers

The RTO 1 Can Tank can continuously operate the rotary valve without switching that it makes it long service life. the exhaust temperature is less than 80 ° C and has low energy consumption, low operating cost

The three-chamber RTO has high exhaust temperature, high energy consumption, and high operating cost. The switching valve works a lot of times per year with a short life span.

The Advantages of Rotary RTO

Regenerative Catalytic Oxidizer(RCO)

RCO system is the same type and structure as the RTO, but by using a special catalyst material added to the oxidizer. The operating temperature inside the combustion chamber below 400° C and increase the rate of oxidation reaction. The system is simple, so maintenance and operation are easy
