Regenerative Thermal Oxidizers (RTO)

The term “regenerative” in regenerative thermal oxidizer is drawn from the type of ceramic media heat exchanger used in these systems. It is unique in that it captures heat from the exhausting, clean airstream during one cycle and releases the heat to the incoming, dirty airstream in the next cycle. The heat is captured (and released) from beds of ceramic media. The RTO incorporates switching valves to cycle the direction of the airflow through the RTO heat exchanger beds to enable regenerative heat recovery.

We can evaluate the existing oxidizer capacity and the requirements of the new process and determine the best approach to upgrade the oxidizer. This could include new heat exchanger media, a larger fan or possibly both. We would also evaluate things like the burner system and combustion chamber size to verify it can provide the required destruction levels. Some applications would be a good match for a VOC concentrator that can significantly concentrate (>10:1) airstreams currently exhausting to the oxidizer.

Please check our RTO Inventory...Quality-built refurbished regenerative thermal oxidizer (RTO) systems have a long life, can save 40% vs. new units, and have performance and parts warranties comparable to new systems.

VOCs must combine with oxygen and heat to trigger the chemical reaction that breaks them down into CO₂ and H₂O. There are many successful thermal oxidizer designs that ensure sufficient turbulence, such as introducing the process air at an angle to induce spin or creating internal choke points. The better the mixing and heat distribution, the higher the VOC destruction.
