Applicable conditions
- Low-concentration odors at high airflows
- Sulfur and nitrogen compounds, alcohols, aldehydes and esters
- Residual odors after conventional scrubbing
- Ducted exhaust or appropriately designed recirculation
Core technology
RAO
Ozone catalytic oxidation — Activates ozone on catalyst surfaces to address low-concentration, high-airflow and mixed odors that are difficult to absorb.
Operating limits
The process uses catalytic activation rather than direct ozone oxidation. Check inlet particles, oil mist, temperature, humidity and condensation risks; provide safety interlocks and residual ozone control.
System combinations
Typical functions include dry filtration, dehumidification and RAO catalytic oxidation. Complex applications can add JETA, chemical filtration or an adsorption backup.
PROCESS & OPERATION
A coordinated pretreatment, reaction and control system.
RAO combines ozone generation and catalytic reaction with filtration, humidity management, fans and monitoring. Suitability for low-concentration odors is verified against the actual operating conditions.
