Our CONCENTRATOR plants can be used to clean effectively and economically large quantities of process exhaust air with a low concentration of hydrocarbons (VOC). They are suitable for large air volumes with low solvent concentrations to convert the large air volume into a small air volume with high solvent concentration. The process air with low solvent concentration is fed through a continuously rotating rotor, where the solvents are adsorbed on the surface of the internal rotor channels. The clean air is released into the atmosphere. A small amount of hot air is fed continuously through a partial rotor segment in counterflow for desorption. The solvents evaporate from the rotor. The solvents enriched in the desorption air stream are then fed to a downstream disposal plant.
- Efficient exhaust air purification by adsorption of pollutants
- High concentration factor
- Energy-efficient exhaust air purification
- Downstream systems can thus be reduced in size
