Recuperative Thermal Oxidizers | Energy-Efficient VOC and Emissions Control
Epcon Industrial Systems is a recognized leader in thermal oxidation technology, specializing in the integration of industrial process heating operations with air pollution control systems. Our Recuperative Thermal Oxidizers provide high-efficiency VOC and hazardous air pollutant (HAP) destruction while maximizing heat recovery for significant energy savings.
A Recuperative Thermal Oxidizer enhances the efficiency of a Direct Fired Thermal Oxidizer (DFTO) by incorporating primary and/or secondary heat recovery, reducing fuel consumption and operational costs. With heat recovery efficiencies of up to 80% and destruction efficiencies reaching 99.99%, Epcon’s recuperative systems deliver superior environmental compliance and cost savings across a wide range of industrial applications.
How Recuperative Thermal Oxidizers Work
Recuperative Thermal Oxidizers utilize a combustion chamber and a proprietary shell-and-tube heat exchanger, designed to optimize temperature, residence time, and turbulence—the three critical parameters for effective thermal oxidation.
- Primary Heat Recovery – Process exhaust gases pass through a heat exchanger before entering the oxidizer, pre-heating the incoming air and reducing the burner’s natural gas consumption.
- Secondary Heat Recovery – Waste heat from the oxidizer is used to support a secondary process, such as an oven, washline, or curing system, often generating enough recovered heat to eliminate external energy sources for these processes.
- Optimized Thermal Performance – Operating temperatures typically reach 1400°F, with residence times of one second to ensure complete VOC oxidation. Higher temperatures are available for chlorinated compound destruction.
By integrating custom-engineered heat recovery systems, Epcon’s recuperative oxidizers allow facilities to achieve significant reductions in fuel consumption, emissions, and operational costs, with potential return on investment (ROI) in less than a year.
Precision Engineering and Manufacturing
Since 1977, Epcon has been at the forefront of thermal oxidation technology, designing and manufacturing advanced recuperative oxidizer systems at our 250,000 sq. ft. vertically integrated manufacturing facility in The Woodlands, Texas.
