Exhaust air purification by concentration

Concentration is a process that combines desorption and thermal after-treatment. It is used for large volumes of exhaust air that have a low content of pollutants. The combination substantially reduces operating costs compared to the purely thermal method.
Concentration offers an alternative to regenerative afterburning.

Concentrators are suitable for all operations that:

• generate large exhaust air flows with a low content of pollutants (from 5,000 m³/hr)
• produce small to medium pollutant concentration (50 to 1,500 mg/m³)
• work with discontinuous or continuous production lines

Benefits:

• very low operating costs
  - because continuous operation is not required
  - the "keep warm" during production stoppage is omitted
  - reduced maintenance since moving flaps accounts
• small required place and easy installation
  - compact design
  - low system weight
  - stand on the roof possible
