Epcon Industrial Systems is a leading provider of Regenerative Thermal Oxidizers (RTOs), engineered for maximum energy efficiency and VOC destruction. With nearly five decades of experience in thermal oxidation technology, Epcon designs and manufactures high-performance RTO systems that meet stringent environmental regulations while optimizing operational efficiency.

A Regenerative Thermal Oxidizer utilizes an advanced heat recovery process to achieve over 95% thermal efficiency, making it an ideal solution for controlling volatile organic compounds (VOCs), hydrocarbons, solvents, and hazardous air pollutants (HAPs) in industrial applications.

Key Components of a Regenerative Thermal Oxidizer

Each RTO system consists of critical components that work together to ensure optimal emission destruction efficiency (DRE) and energy recovery:

• System Fan – Provides controlled airflow for efficient oxidation.
• Motor – Drives system operations with precise performance.
• Combustion Chamber – Designed for complete VOC and HAP destruction.
• Burner (Low NOx Available) – Minimizes nitrogen oxide emissions while ensuring full combustion.
• Heat Recovery Towers (Heat Exchangers) – Maximize thermal efficiency and energy savings.
• Heat Exchange System – Available in structured, packed beds, and silica-tolerant configurations.
• Flow Control Valves – Ensure proper gas flow distribution for consistent performance.
• Electronic and Automatic Controls – Integrated for precision operation and monitoring.
• Temperature Recorder – Provides real-time process temperature data for compliance monitoring.
• UL Panel – Ensures safety and reliability with certified electrical controls.
• Exhaust Stack – Facilitates safe discharge of treated air.

Designed for long-term durability, RTOs feature an outer structure made of ceramic fiber-lined steel, engineered for maximum thermal retention and efficiency.

Engineering Expertise and Advanced Thermal Oxidizer Technology

Since 1977, Epcon has designed and manufactured thousands of thermal oxidizer systems for industrial VOC and air pollution control systems. Each system undergoes a rigorous pre-engineering and front-end analysis, ensuring optimal system performance and efficiency. Using advanced design and drafting technology, followed by state-of-the-art manufacturing, Epcon delivers custom-engineered RTOs tailored to specific process requirements.

Energy Efficiency and Heat Recovery

Unlike Recuperative Thermal Oxidizers, which rely on direct heat transfer, Regenerative Thermal Oxidizers utilize multiple energy recovery chambers with ceramic heat recovery media. This flow reversal process allows for exceptional heat retention, significantly reducing fuel consumption and operational costs.

As contaminated process air enters the RTO, it passes through ceramic media beds that absorb and store heat. The pre-heated exhaust stream then enters the combustion chamber, where it is oxidized at high temperatures to break down harmful pollutants. By continuously cycling between heat recovery chambers, RTOs achieve high thermal efficiency while minimizing fuel usage.

Custom-Designed RTO Systems for Industrial Applications

Epcon understands that every process has unique emissions control requirements. Our custom-engineered RTOs are available in a range of configurations and materials, including carbon steel, stainless steel, and high-performance alloys, ensuring compatibility with demanding industrial environments.
