Zeolite Rotor Concentrator
Molecular sieve rotor systems that concentrate large-airflow, low-concentration VOCs before oxidation—cutting energy cost.
Where Zeolite Rotor fits
When exhaust volume is high but solvent concentration is low, oxidizing the full stream is expensive. A zeolite rotor adsorbs VOCs from the process air and desorbs them into a much smaller, richer stream sized for RTO or catalytic oxidation.
Large airflow, low concentration VOCs (coating, printing, electronics)
Catalog range for combined systems
Media-dependent working range
High-boiling duty option
How the system works
The rotor turns continuously through adsorption, desorption, and cooling zones. Large process airflow is cleaned in the adsorption sector; a smaller desorption airflow carries concentrated organics to the downstream oxidizer.
- 01Large-volume process air enters the adsorption zone.
- 02Zeolite media captures compatible VOC molecules.
- 03A small heated stream desorbs and concentrates the VOCs.
- 04The concentrated stream is sent to RTO or catalytic oxidation.
Choose by process conditions
| Configuration | Description | Best fit | Source metric |
|---|---|---|---|
| Disc Zeolite Rotor | Axial-flow rotor with a large frontal adsorption area and established modular sizing. | Large, stable process airflows and conventional coating or printing duty. | Project-specific |
| Cylindrical Zeolite Rotor | Radial-flow cylindrical media designed for greater adsorption area within a compact envelope. | Compact layouts, higher-boiling components, and projects prioritizing lower pressure drop. | Project-specific |
| Integrated Or Split Package | Rotor, desorption, fan, heat exchange, and oxidation arranged as one package or separate modules. | Export skids, retrofit sites, and layouts with restricted equipment zones. | Project-specific |
