Applications
Select an application to see how OxiTherm thermal oxidisers address specific finish-line emission challenges.
Industrial and automotive spray booths generate large volumes of exhaust air containing low concentrations of complex solvent mixtures (xylene, toluene, MEK, acetates). These emissions must be controlled to meet IED BAT limits and local air quality permits. When combined with a rotor concentrator, our OxiTherm regenerative thermal oxidisers efficiently destroy 99% of spray booth VOCs, converting large-volume, low-concentration streams into a low-volume, high-concentration flow that enables autothermal combustion and drastically reduces fuel costs.

Industrial Finishers
Key advantages of OxiTherm systems for handling the volatile, condensable, and high-volume constraints of industrial coating.
99% VOC Destruction
Regenerative thermal oxidation destroys complex paint solvents, thinners, and curing byproducts — ensuring full compliance with IED BAT-AELs and local permits.
98% Energy Recovery
Advanced ceramic heat exchangers return 98% of thermal energy, slashing the fuel costs required to heat large volumes of spray booth or oven exhaust to combustion temperatures.
Condensable Tolerant
Engineered specifically for coating applications with insulated plenums, self-cleaning bake-out modes, and block-resistant media to prevent resin and caprolactam fouling.
Rotor Integration
Seamlessly pairs with zeolite rotor concentrators for spray booth applications, concentrating VOCs up to 20x to shrink oxidiser size and enable zero-fuel autothermal operation.
Oven Heat Integration
Surplus thermal energy from the oxidation chamber can be ducted directly to curing ovens or wash lines, offsetting secondary heating costs and shortening ROI.
Variable Production Ready
Modulating burners automatically adapt to varying solvent loads during colour changeovers, part loading delays, and line speed adjustments without stalling or tripping.
Fuel Your Cure Ovens
With Your Exhaust
Paint lines run intense burner systems to hit curing temperatures. OxiTherm systems capture heat from destroying your solvent emissions and pipe it straight back to offset those curing and washing costs.
Recovered Heat Slashes
Curing & Washing Costs.
Whether you run batch ovens or massive continuous automotive lines, finding efficiency in heating loops is key to margin. By intercepting 98% of the heat created by destroying your solvents, OxiTherm systems provide a massive, free thermal resource to the rest of the facility.
Ducted straight from the oxidiser, clean hot air at 150-250°C is fed directly into curing and baking ovens, severely reducing main burner firing rates.
Using an air-to-water heat exchanger, we safely heat aqueous wash phases and phosphating baths prior to powder coating or wet painting.
In cooler climates, recovered energy tempers the massive volumes of incoming make-up air required to keep spray booth conditions controlled and comfortable for painters.
Warm exhaust air is utilized to rapidly evaporate moisture off parts exiting the wash line before they hit the booth, speeding up overall line pace.

FAQs
Common questions covering abatement for spray booths, powder curing, and finish lines.
For direct RTO treatment, yes. However, for high-volume/low-concentration spray booth exhaust, we integrate the OxiTherm RTO with a Zeolite Rotor Concentrator. The rotor concentrates the VOCs by 10x to 20x, meaning the RTO only needs to process a fraction of the total air volume. This drastically reduces the capital cost of the RTO and makes the system autothermal, requiring almost zero supplementary fuel during normal operation.
Fouling from condensables (like caprolactam or resins) is a common issue with standard RTOs in coating applications. OxiTherm systems solve this using insulated cold-face plenums to prevent premature condensation, structured ceramic media designed to resist plugging, and automated "bake-out" modes that periodically elevate temperatures to burn off any organic buildup before it restricts airflow.
Yes. Curing ovens often release huge solvent spikes when a new batch enters, followed by a taper. OxiTherm systems use fast-acting modulating burners and variable frequency drives (VFDs) that respond in under 5 seconds. If the solvent load spikes dangerously high, standard integrated hot-gas bypass valves automatically divert excess heat to protect the equipment while maintaining 99% destruction.
In paint and coating facilities, the most lucrative heat recovery application is ducting the hot, clean exhaust air directly back into the curing ovens or dry-off ovens. Secondary heat exchangers can also be used to generate hot water for part-washing and phosphate-coating prep lines, significantly reducing your site's overall heating fuel consumption.
Yes. Paint lines generate overspray particulate that must be managed. We design complete systems including multi-stage particulate pre-filtration (such as pocket filters or HEPA stages) upstream of the RTO or rotor concentrator. This ensures that sticky paint dust never reaches the delicate ceramic media or zeolite wheel, extending media life to 7–10 years.
OxiTherm systems destroy the full spectrum of coating solvents: toluene, xylene, MEK, MIBK, ethyl acetate, butyl acetate, alcohols, and complex aliphatic thinners. The high operating temperature of 850–1,100°C combined with a 2.0-second residence time guarantees complete oxidation regardless of the paint or coating chemistry you are spraying.
