Regenerative Thermal Oxidisers (RTOs)

Process Combustion’s RTOs are available as a range from low-cost two canister packaged units that come to site completely containerised, to bespoke large canister systems with advanced features such as on line bake-out and secondary heat recovery.

All our RTOs offer high destructive efficiency of VOCs combined with superb energy efficiency and low running costs – little or zero fuel in-put. In cases where heat contribution of the VOCs is significant the RTO can release excess energy and redirect it to secondary heat recovery.

Key benefits include:

  • Handles high to low VOC concentrations
  • Very high VOC destruction rate – up to 99.5%
  • Up to 96% primary heat recovery
  • Secondary heat recovery can be installed to heat hot oil, water or air
  • Extremely low fuel costs even at low solvent concentrations
  • Easy to use advanced control systems.




Process Combustion has a 30 year track record of working in the combustion and heat transfer technology sector with famous-name industrial giants in oil, gas and manufacturing industries around the globe. Our reputation for custom made solutions can be brought to bear in the early engineering stages of a major system build to explore feasibility and process.

Design and Project Management

Our in-house design expertise covers process, mechanical, structural, electrical, controls, material selection and sourcing. Working to the specified processes we work with clients to seamlessly integrate our equipment to deliver cost effect solutions while meeting the most stringent emission limits.

Our established relationships with clients, suppliers and sub-contractors combined with proven project management skill-sets ensure that systems are completed that meet required documentation and technical standards and are on budget, on time, every time

Engineering and Manufacturing Excellence

We work in an exacting industry where quality assurance standards (BS EN ISO 9001; 2000 Quality Management System approved) and rigorous engineering capability are paramount. Process Combustion’s 2500 m2 production area with up to 16 tonnes crane capacity and state-of-the-art control system build and test workshop exemplify our approach to everything we manufacture.

We design and build to the latest international codes and standards; these include European Pressure Equipment Directive, ASME, API, AWS, NFPA, EN and ATEX.

Installation & Support

We can either construct on site or work with our clients’ own construction teams in a supervisory role. Accurate and speedy Installation and commissioning are vital ingredients in a successful project system completion.

Process Combustion provides itself on our commissioning and operator training facilities. After sales service back-up includes providing spare parts and our service engineers continue to support on-going site activities to ensure trouble-free running and efficient operating procedures are adhered.
