Custom systems designed and optimised for your exhaust air challenges – from analysing the exhaust air to ensuring compliance with limit values during continuous operation.

We clean industrial exhaust air
– to ensure compliance with all emission limits
Whether battery test rigs, painting and coating systems, fuel cell production or chemical processes: many industrial processes generate airborne pollutants that must not be released untreated into the ambient air and are subject to strict emissions limits. Increasing regulatory requirements and the ambition to make processes cleaner and more resource-efficient make reliable exhaust air treatment an essential prerequisite for operation.
The real challenge lies in the variety and complexity of the exhaust air: fluctuating flow rates, high temperatures, changing solvent mixtures, solid particles, acids and, in some cases, unknown or future emissions scenarios.
That is precisely why PlasmaAir does not offer off-the-shelf systems. We build bespoke systems: each one is designed for the specific process, tailored to the actual pollutant load and dimensioned to meet future requirements and accommodate extensions. Where necessary, we combine our processes – from plasma technology to wet scrubbers, adsorption and filtration – to create a multi-stage solution that captures exactly the substances generated in your process.
From the initial discussion through analysis, design and manufacture to commissioning and maintenance, you get everything from a single source – with one dedicated contact who knows your process and your system.

Safely and reliably clean even hot exhaust air streams.
[05]
Reliably reduce odours
Odorous emissions are effectively captured.
[06]
Recover CO₂
Capture carbon dioxide directly from the surrounding air and put it to use.
SOLUTIONS
[01]
Wet scrubbers, dry filters
The choice of suitable technology depends on the temperature, concentration and constituents of the exhaust air.
[02]
Düsenbodenwäscher, chemical scrubbers, activated carbon filters
These systems are used depending on the water solubility and concentration of the pollutants.
[03]
Chemical scrubbers, packed-bed scrubbers
Through targeted dosing of acid or alkali, pollutants are efficiently neutralised and precipitated.
[04]
Quenching stage with wet scrubber
Depending on the requirements, cooling and cleaning are carried out using water or chemical scrubbing.
[05]
Biofilters or chemical scrubbers
The right solution depends on the water solubility of the substances to be separated.
[06]
Chemical scrubbers using amine solutions
Optimised for CO₂ capture from ambient air or point sources
