Regenerative Thermal Oxidisers (RTOs)

At Operational we install, repair and care for all types of oxidiser.

We are completely impartial from any oxidiser manufacturer meaning we have our clients’ interests at the heart of our operations.

Over the next few months we will be talking about the different types of oxidiser, their potential benefits and what they actually do.

Regenerative thermal oxidisers

An RTO is a piece of industrial equipment used to treat process air streams. A regenerative thermal oxidiser destroys Volatile Organic Compounds and odorous emissions that are emitted from a number of industrial or manufacturing processes. Regenerative Thermal Oxidisers achieve emission destruction through the process of thermal oxidation, using an engineered mix of temperature, residence time, turbulence and oxygen to convert the laden process air into carbon dioxide and water vapour. All Regenerative Thermal Oxidisers utilise ceramic bed technology which enables this type of thermal oxidiser to provide a high efficiency destruction of VOC and odorous emissions, whilst providing operational energy based savings due to the thermal capture capabilities of the ceramic media, used within a Regenerative Thermal Oxidiser. 99% efficiency in treating VOCs, thermal efficiency from ceramic beds. .5 – 1.0 secs the minimum period of time, known as resonance time that a pollutant must be burnt at a specified temperature. 800-850 degrees Celsius are typical temperatures of a RTO. Industries used in: Printing and packaging to treat emissions and print drying processes in food wrapping, bags and packaging. Utilities: tackling odours from sewerage treatment plants and municipal waste. Automotive industry: emissions from printed components such as car dashboards. Metal industry: RTOs are used to treat emissions from processes such as aluminium casting into resin-impregnated sand moulds.
