What is industrial painting?

Industrial painting is a key process in many industries – from the automotive industry and mechanical engineering to furniture production. The aim is to protect and finish surfaces and to optimise their function. Various methods are used, such as spray painting, powder coating or dip coating.

Challenge: VOC emissions in painting processes

Industrial painting releases considerable quantities of volatile organic compounds (VOCs).

These mainly originate from:

Solvents in the paint
Evaporation during flash-off
Thermal load during curing

The role of catalysts in exhaust air treatment

To reduce VOC emissions effectively, catalytic exhaust gas treatment systems are used in industrial painting plants.

Catalysts enable pollutants to be oxidised at significantly lower temperatures than purely thermal processes:

VOCs → CO₂ + H₂O

This means:

Lower energy consumption combined with high cleaning performance

Advantages of catalytic solutions for painting plants

High removal efficiency

Reliable removal of VOCs and odorous substances – even under fluctuating loads

Energy savings

Lower operating temperatures considerably reduce energy demand

Compact design

Well suited for integration into existing painting lines

Sustainability

Significant improvement in environmental performance

Answers on technology, legislation and processes.

What effect do catalytic converters have on energy consumption?sechmarketing2026-03-27T13:55:41+01:00

What effect do catalytic converters have on energy consumption?

As catalytic oxidation takes place at lower temperatures, less energy is required for exhaust air purification. This can significantly reduce operating costs and improve the overall energy efficiency of the system.

Can existing painting systems be retrofitted?sechmarketing2026-03-27T13:55:26+01:00

Can existing painting systems be retrofitted?

Yes, many systems can be retrofitted or optimized with catalytic systems. A precise analysis of the exhaust air flows is crucial in order to integrate the right solution.

Why are VOCs such a big issue in paint shops?sechmarketing2026-03-27T13:54:44+01:00

Why are VOCs such a big issue in paint shops?

Paints often contain solvents that are released as VOCs when they evaporate. These are harmful to the environment and health and are subject to strict legal requirements, which makes effective exhaust air purification absolutely essential.

Which process steps produce the most VOC emissions?sechmarketing2026-03-27T13:54:24+01:00

Which process steps produce the most VOC emissions?

The highest VOC emissions typically occur during paint application, flash-off and thermal curing. Continuous exhaust air flows from drying ovens are particularly critical.
