Regenerative Thermal Oxidizers (RTO)

regenerative thermal oxidizer supplier offering new and refurbished equipment
New RTO Project?
Help With An Existing RTO?

A regenerative thermal oxidizer (RTO) is an air pollution control device that destroys VOCs and hazardous air pollutants (HAPs) in industrial exhaust air. By using regenerative heat recovery, it achieves high fuel efficiency, often operating with 95% heat recovery. As an RTO supplier, Kono Kogs helps facilities evaluate new custom-built and refurbished systems to find the right fit for their needs.

All FAQs

What is the dwell time in a regenerative thermal oxidizer?

Regenerative thermal oxidizers (RTOs) typically have a 0.5 second to 1.0 second dwell time for most applications.

At what temperature does a regenerative thermal oxidizer operate?

RTOs typically operate at 1500o – 1600o Fahrenheit depending upon the VOC characteristics. Thermocouples inside the chamber monitor temperature and adjust gas burner firing as needed. Adequate temperature is essential to ensure VOC destruction efficiency. In most cases a data log of chamber temperature is required for air quality compliance.

Does the RTO main fan use a variable frequency drive (VFD)?

Yes, most RTO systems are equipped with a VFD on the main fan. VFDs are important for efficient operation, allowing for volume turn-down, improved energy savings, and idle-mode operation when full airflow isn’t needed.

‍

What is the operating temperature of a thermal oxidizer?

Typically 1400° F minimum up to 1550° F depending upon the VOC characteristics. Read more in Operating Temperatures of Different Oxidizers.

What does the burner do in an RTO?

The burner provides the heat required to raise the gas stream to the oxidation temperature needed to destroy VOCs.
