Exhaust air purification for modern production lines
Industrial exhaust air purification removes VOC-containing exhaust air from industrial finishing, coating and drying processes safely and energy-efficiently. At Venjakob, we develop thermal systems that achieve high levels of purification and can be precisely integrated into different production environments. Stable system operation, intelligent heat utilisation and reliable control logic support economical and emission-compliant processes.
Exhaust air purification through Incineration processes
Incineration is the most important process in industrial exhaust air purification and ensures that VOCs and other organic components are safely oxidised. It is suitable for exhaust air flows with different levels of pollution from coating, drying or adhesive processes and forms the basis for stable, legally compliant emission values.
Venjakob relies on proven thermal, regenerative and catalytic processes, which are selected according to energy requirements, volume flow and load.
Complementary processes for exhaust air purification
In addition to thermal processes, exhaust air systems can be expanded to include adsorption, concentration and energy recovery. These supplementary processes enable an increase in efficiency in certain exhaust air situations and support energy-optimised system operation.
Adsorption and concentration (zeolite)
Zeolite rotors are used for concentration, which adsorb VOCs from large, low-pollution exhaust air streams. The concentrated exhaust air is then thermally oxidised, which reduces the energy requirement of the main process and improves system efficiency.
Energy recovery in exhaust air systems
Thermal energy can be recovered from purified exhaust air via heat exchangers or regenerative storage units. This heat can be utilised in dryers, process air or for hall heating and significantly reduces the overall energy requirement.
Advantages of exhaust air purification
Coordinated exhaust air purification increases operational safety, stabilises production processes and enables emission-compliant production. At the same time, it improves energy efficiency and supports sustainable production targets.
- High VOC degradation performance
- Efficient heat utilisation
- Stable values in accordance with TA-Luft
- Durable system technology
- Precise integration in coating, drying and process air
Exhaust air purification in the Venjakob process chain
Exhaust air purification is an integral part of the Venjakob process chain and completes coating, drying and process air systems in a technically sensible way. Coordinated interfaces create a consistently controllable, stable and energy-optimised production process. The linked control system improves transparency, safety and efficiency.
Modern exhaust air purification fulfils strict environmental regulations and ensures safe working conditions. Lower emissions, controlled temperature management and maintenance-friendly designs contribute to sustainable system operation. Safety and explosion protection functions ensure a reliable process even under changing operating conditions.
Future trends in exhaust air purification
Digital and energy-optimised exhaust air purification systems are becoming increasingly important. AI-supported controls automatically adjust air volumes and temperatures to the VOC load. Improved storage ceramics increase heat recovery, while networked control systems seamlessly integrate exhaust air purification into the entire production process.
