Regenerative Thermal Oxidizer (RTO)

B&W MEGTEC offers a range of regenerative thermal oxidizer (RTO) designs and configurations to meet your needs and provide the best solution for your application.

  • Economical two-chamber, single vessel design
  • Modular, multi-canister design
  • Modularly designed single bed, compact, flameless RTO with low operating costs
  • Customized application design needs, with extended residence times, gas scrubbers for off-gas clean-up, concentrators, and specialized materials of construction

Our RTOs are designed for low to high volume air flows with high thermal and VOC destruction efficiencies. In many applications, the system will run in a self-sustaining mode whereby no additional fuel is required to destroy VOCs
