Thermal oxidation
Minimise pollutants, maximise efficiency: Durable, safe, and easily accessible - our thermal oxidation systems efficiently treat pollutant-laden exhaust air streams and feature integrated heat recovery.
Your complete solution: personally designed, personally delivered
Does the exhaust air from your production facilities contain a high solvent load? With thermal oxidation, you can process these problematic exhaust air streams smoothly while recovering heat for your production. Eisenmann Environmental Technology is your personal partner for this complex task.
Worldwide, we provide you with a full range of services from a single source — from concept development through implementation to after-sales service. The result: a tailor-made complete solution that sustainably optimises your production processes. Benefit from our experience gained from more than 1,300 systems built.
How thermal oxidation systems work
Thermal oxidation systems convert organic pollutants into carbon dioxide and water through oxidation. In this process, the exhaust air is first preheated and then fed into the combustion chamber at temperatures between 700 and 1,200 °C.
After oxidation, the heat can be recovered using the following systems:
- Warm water, hot water, or steam generation
- Air heating
- Transfer to other heat carriers such as thermal oil
- ORC process
Have your solution flexibly designed
Your operational requirements determine how we design and build your thermal oxidation system. Where sufficient space is available, all system components can be arranged in line — on a single level. If your installation area is limited, we build your system individually, including on multiple levels.
Your benefits with our thermal oxidation systems
Thanks to the modular design, we can efficiently tailor the system to your requirements. This enables compliance with a wide variety of specifications for volume flows and solvent loads.
- Structured design: Our thermal oxidation systems offer optimal accessibility both during operation and for maintenance purposes.
- Durable: The robust construction ensures high operational reliability and a long service life. We have thermal oxidation systems that have been in operation for well over 20 years.
Safe and efficient
Our Eisenmann BLUEMAX burner meets the strict carbon monoxide requirements. At the same time, it ensures that the legal limits for total organic carbon and nitrogen oxides are clearly undercut.

Frequently asked questions about thermal oxidation (TO systems)
What is a thermal oxidiser (TO)?
A thermal oxidiser (TO) is a technology used to treat industrial exhaust air. Volatile organic compounds (VOCs), odorous substances and other pollutants are oxidised at high temperatures and converted into carbon dioxide, water vapour and other harmless reaction products.
How does a thermal oxidiser work?
In a thermal oxidiser, contaminated exhaust air is directed into the system and heated to the required oxidation temperature. The combination of temperature, residence time and turbulence ensures reliable destruction of pollutants before the cleaned exhaust air is discharged through the stack.
When is a thermal oxidiser used?
A thermal oxidiser is used when industrial processes generate pollutant laden exhaust air and emission limits must be reliably met. Typical applications include the paint and coatings industry, the chemical and pharmaceutical industries, the printing industry, as well as coating and drying processes.
What destruction efficiency can a thermal oxidiser achieve?
Modern thermal oxidisers achieve very high destruction efficiencies, depending on the specific application and process conditions. In many industrial applications, VOC destruction efficiencies of more than 99% can be achieved.
What is the difference between a thermal oxidiser (TO) and an RTO system?
In a thermal oxidiser (TO), heat is typically recovered using heat exchangers. A regenerative thermal oxidiser (RTO) uses ceramic heat exchange media to recover significantly larger amounts of heat, making it particularly suitable for high air volumes and low pollutant concentrations. Eisenmann Environmental Technology supports customers in selecting the technically and economically optimal solution for their specific application.
What are the advantages of a thermal oxidiser?
Thermal oxidisers provide high destruction efficiencies, reliable operation and support compliance with regulatory emission limits. By utilising process heat, they can also help reduce energy consumption and operating costs. Eisenmann Environmental Technology develops thermal oxidisers tailored to specific production processes and customer requirements.
How energy efficient is a thermal oxidiser?
The energy efficiency of a thermal oxidiser depends on factors such as exhaust air volume, pollutant concentration, exhaust air temperature and the level of heat recovery. Modern system designs reduce fuel consumption by optimising the utilisation of the heat already available within the process.
Which industries are thermal oxidisers suitable for?
Thermal oxidisers are used across a wide range of industries, including the paint and coatings industry, the chemical and pharmaceutical industries, the printing industry, as well as coating and drying processes that generate VOC laden exhaust air.
What does a thermal oxidiser cost?
The cost of a thermal oxidiser depends on factors such as exhaust air volume, pollutant load, heat recovery requirements, the degree of automation and project specific requirements. A reliable cost estimate can therefore only be provided based on the specific process data and operating conditions.
How is a thermal oxidiser designed?
The design of a thermal oxidiser is tailored to the specific application and is based on factors such as exhaust air volume, pollutant type and concentration, temperature, operating hours and the applicable emission limits. Eisenmann Environmental Technology considers both technical and economic requirements to develop the optimal system solution for each project.
What should you consider when selecting a supplier for thermal oxidisers?
Key factors when selecting a supplier for thermal oxidisers include experience, technical expertise and the ability to provide a system tailored to the specific application. With experience from more than 1,300 installed systems, Eisenmann Environmental Technology supports customers from concept development and engineering through to service, delivering customised solutions for a wide range of production processes and emission control requirements.
