RTO/RCO

Regenerative Thermal (Catalytic) Oxidizer

Principle/Advantage

  • Recovers residual heat from heat storage material by continuously changing the gas flow direction with a rotary rotor.
  • Exhibits exceptional energy savings with a heat recovery rate exceeding 95%, while maintaining stable operation and eliminating pressure fluctuations.
  • Features an integrated stack system that simplifies maintenance, reduces investment costs, and allows for easy inspection of heat storage materials and rotors.
  • Applicable to a wide range of VOC concentrations (100 to 2,000 ppm, based on THC) and air volumes (100 to 1,000,000 m3/h)
  • Utilizes both direct and catalytic oxidation mechanisms to thermally convert VOCs and odorous substances into harmless gases.
