Optimize high-volume emissions with a rotary concentrator thermal oxidizer system. Cadair.net combines zeolite rotors with RTO/CO units to reduce operating costs by up to 90%.
Solving the “High Volume, Low Concentration” Dilemma
In industrial air pollution control, the most challenging exhaust profile is High Volume, Low Concentration. Treating 100,000 CFM of air with only 50 ppm of VOCs using a standalone thermal oxidizer is financially ruinous due to natural gas costs.
The solution is the rotary concentrator thermal oxidizer system. At ABOUT US, we engineer these hybrid systems to “shrink” your pollution problem before destroying it.
1. How the Combined System Works
A rotary concentrator thermal oxidizer integrates two distinct technologies into one seamless process:
- Concentration (The Rotor): A large volume of cool, dilute air passes through a spinning Zeolite Concentration Rotor(CR). The hydrophobic zeolite adsorbs the VOCs, allowing clean air to be vented to the atmosphere.
- Desorption (The Transfer): A small stream of hot air (typically 1/10th to 1/20th of the original volume) passes through a isolated sector of the rotor. This releases the trapped VOCs, creating a highly concentrated, low-volume stream.
- Destruction (The Oxidizer): This small, potent stream is sent to a compact RTO or Catalytic Oxidizer (CO). Because the volume is so low and the concentration is high, the oxidizer often runs in a self-sustaining (autothermal) mode, requiring little to no auxiliary fuel.
2. Benefits of the Hybrid Approach
Why invest in a rotary concentrator thermal oxidizer instead of a massive standalone RTO?
- Massive Energy Savings: By treating only 5-10% of the total airflow, fuel consumption drops by up to 90-95%.
- Lower Capital Cost (CAPEX): A small oxidizer (e.g., 5,000 CFM) is significantly cheaper than a giant one (e.g., 50,000 CFM), offsetting the cost of the rotor.
- Space Efficiency: The footprint of a hybrid system is often smaller than a massive multi-canister RTO.
3. Ideal Applications
This technology is the industry standard for sectors with large ventilation requirements:
- Semiconductor Manufacturing: Handling dilute solvent exhaust from cleanrooms.See: Semiconductor / LED / Display / Photovoltaic / PCB
- Automotive Spray Booths: Treating huge volumes of paint overspray.See: Automobile & Parts Manufacturing
- LCD / Display Panel Production: Managing wide-area coating emissions.
Conclusion: Integrated Engineering
Designing a rotary concentrator thermal oxidizer requires expertise in both adsorption physics and combustion thermal dynamics. Cadair manufactures both the rotor cassettes and the oxidizers, ensuring perfect integration.
