The application of Deparia’s rotor-concentrators is very interesting to reduce the overall investment costs compared to the installation of a large rto designed for the entire air flow.

Abatement of volatile organic substances found in most industrial emissions

Zeolite-based rotor-concentrators are used for the abatement of volatile organic substances found in most industrial emissions, in case of low concentration of pollutants and high gas flow rate.

The volatile organic compounds contained in the airflow are concentrated by adsorption in the concentrator consisting of the zeolite rotor. The clean air flow is sent directly to the chimney. The pollutants concentrated in the rotor-concentrator are desorbed and finally treated by a small thermal oxidizer.


Ideal at high emission rates and relatively low solvent concentrations.


Low management and maintenance costs .


Reduced oxidizer plant dimensioning.
