The Epsilon RTO from Dürr Megtec is a modularized multi-canister oxidizer offering a highly flexible design that makes it appropriate for many applications where volatile organic compounds (VOCs) and hazardous air pollutants (HAPs) must be managed, and odor control requirements must be met.

RTOs are proven to be thermally efficient volatile organic compound (VOC) emission control systems. The Epsilon RTO features an innovative compact design that is engineered to deliver low operating and capital costs, and guaranteed VOC destruction efficiencies.

  • Tailored heat-exchange media designed for optimized thermal efficiencies, minimized pressure drop and organic/inorganic contaminants.
  • Highly reliable poppet valve design with 15+ years of field application.
  • Destruction efficiencies of 99.8% to meet the most-stringent global emission codes.
  • Optional hot-side bypass system for use with high solvent load applications.
  • Ceramic media bake-out cleaning for removal of organic deposits, with smoke-free emission options.
  • Optional secondary heat recovery for hot water, thermal oil, steam, electricity generation or adsorption cooling.
  • Multiple fuel options such as natural gas, butane, propane and oils.
  • Optional fuel gas injection systems.
  • Variable cycle time and temperature profile control for process-harmonized operation.
  • Heavy-duty construction with independent canisters for long operation.

In applications where a multi-canister oxidizer is required, the Epsilon RTO from Dürr Megtec can be configured with three (3), five (5) or more canisters. The Epsilon RTO features a modular, highly flexible design to meet specific performance criteria. With its innovative compact design, the unit delivers effective VOC destruction with low operating and capital costs. Read more about the Epsilon RTO.

EPSILON RTO with thermal oil heat recovery

The EPSILON regenerative thermal oxidiser (RTO) from Babcock & Wilcox MEGTEC (B&W MEGTEC) is a modularized multi-canister oxidiser offering a highly flexible design that makes it appropriate for many applications.

RTOs are proven to be thermally efficient volatile organic compound (VOC) emission control systems. The EPSILON RTO features an innovative compact design that is engineered to deliver low operating and capital costs, and guaranteed VOC destruction efficiencies.

EPSILON RTO modular design is suitable for large and small spaces

Each EPSILON RTO system features structured ceramic heat exchange media as the integrated inlet and outlet air channels combined with the Dürr MEGTEC patented low-leakage poppet dampers to create superior system performance.

The MEG@Control PLC monitors and controls the temperature in the heat exchanger beds and combustion chamber via multiple thermocouples located in the system. This helps to allow cost-effective operation and a long production life.

EPSILON RTO 55.000 Nm³

The MEG@Save system minimizes energy usage and is a standard feature for most applications.
