NESTEC’s Direct-Fired Thermal Oxidizers (DFTO) are designed for the efficient destruction of Volatile Organic Compounds (VOCs) and Hazardous Air Pollutants (HAPs) without the use of heat recovery components. These oxidizers are ideal for applications where fuel costs are less of a concern, but high VOC destruction is required. DFTOs operate by directly exposing pollutants to extremely high temperatures, ensuring rapid and complete oxidation.

• Simple Design: Lacks heat recovery components, making the system straightforward and efficient for high VOC destruction.
• High Destruction Efficiency: Achieves VOC and HAP destruction rates of up to 99% through direct combustion.
• Fast Response: Ideal for processes requiring quick heat-up times and high processing rates.
• Durable Construction: Designed with robust materials to handle extreme temperatures and provide long-lasting performance.

How DFTOs Work

In Direct-Fired Thermal Oxidizers, exhaust gases containing VOCs or HAPs are fed into a combustion chamber where they are exposed to high temperatures (typically over 1400°F). The pollutants are oxidized rapidly, breaking down into carbon dioxide and water vapor. Unlike other thermal oxidizers, DFTOs do not employ heat recovery, focusing solely on fast and efficient destruction of pollutants​.
