CADAIR offers high quality regenerative catalytic combustion furnaces (RCO), ideal for handling low concentrations of hazardous air pollutants (HAPs) and volatile organic compounds (VOCs). RCO is an advanced upgrade of the traditional RTO system.
The system includes three or more regenerative chambers filled with ceramic media that cyclically absorb and release heat, achieving heat recovery during VOC oxidation.
In the middle of the thermal storage layer, 2 to 3 layers of catalysts are added, enabling VOCs to combust efficiently at lower temperatures (260–300 °C). This significantly reduces energy consumption and operating cost.
Thanks to the ultra-high heat recovery efficiency (≥95%), even if VOC concentrations are below 1,000 mg/Nm³, the system requires almost no additional heat during operation — making it an exceptionally energy-saving solution.
Note: Catalysts may lose activity over time if the gas contains heavy metals (e.g. lead), toxic elements (e.g. sulfur, phosphorus, arsenic), or halides (e.g. chlorine, bromine, fluorine), as these substances can bind irreversibly with catalyst materials.
