Recuperative Thermal Oxidizers

VOC abatement using Recuperative Thermal Oxidizers is appropriate in many process applications including processes where particulate may be present, with higher Volatile Organic Compound (VOC) concentrations or even where a large amount of heat energy may be needed somewhere else in your facility.

Pollution Systems’ Recup TO designs are able to incorporate many energy-saving options including the use of preheated combustion air, a secondary heat exchanger and sophisticated burner controls. Pollution Systems will work closely with you to understand the trade-offs between initial capital investment and the expected savings in operating costs associated with Recup TO technology and available options.

Recuperative Thermal Oxidizer Components

Recuperative Thermal Oxidizer systems incorporate a heat exchanger with a combustion chamber and can handle a wide range of process flow rates and VOC concentrations. The heat exchanger is used to preheat the VOC laden air prior to entering the combustion chamber to reduce operating cost.  See Drawing below:


How a Recuperative Thermal Oxidizer works


Each system comes with a suite of Automated System Controls to optimize the unit's performance by improving safety, providing minimal operator interface, and allowing easy start-up and operation with a touch of a button.

Recuperative Thermal  Oxidizers are:


  • Ideal for Moderate VOC concentrations
  • Suitable for Secondary Heat Recovery
  • Typically able to achieve destruction efficiency in excess of 99%   
  • Capable of thermal efficiency up to 80%


Common Recuperative Thermal Oxidizer Industrial Applications

There are several industrial processes used by companies world-wide where a Recuperative Thermal Oxidizer makes sense. Some of those processes are utilized by:


Recup TO Resources
