airprotech supplies zeolite-based VOC rotor-concentrators that are typically installed in case of low concentration of pollutants and large gas flow rate.
The volatile organic compounds VOC contained in the laden air flow are concentrated by adsorption in a zeolite-based rotor-concentrator. The cleaned air flow is delivered directly to the exhaust stack. The pollutants concentrated in the rotor-concentrator are desorbed and finally treated by a thermal oxidizer with reduced size.
The application of rotor-concentrators is very interesting to reduce the overall investment costs compared the installation of a large size RTO designed for the entire air flow rate.
