The exhaust gas passes through a ceramic heat-storage bed into the oxidation chamber, where volatile organic compounds are oxidized.
A catalyst enables volatile organic compounds to be oxidized at lower temperatures.
A fan conveys the exhaust air into the unit, where it is first preheated in a recuperative heat exchanger.
The exhaust air is preheated to the oxidation temperature in a heat exchanger. Thanks to the catalyst, this temperature is lower than in thermal oxidation.
Exhaust gas containing high pollutant concentrations is fed directly into the oxidation chamber. With the correct residence time and oxidation temperature, hazardous substances are converted into harmless products.
The exhaust air passes through a rotor where VOCs are first adsorbed onto a hydrophobic zeolite adsorbent and then desorbed into a small stream of heated air.
For large air volumes with low VOC concentrations, a fixed-bed activated carbon adsorber is an effective solution. The exhaust air passes through the activated carbon bed, where the VOCs are adsorbed.
