  3. General Information
    1. A zeolite rotor with RCO is an industrial air pollution control system that uses a zeolite rotor concentrator to capture and concentrate volatile organic compounds (VOCs) from large air volumes, which are then fed into a regenerative catalytic oxidizer (RCO) to be destroyed.
    2. This combined system is highly effective for treating large, low-concentration air flows, as the rotor significantly reduces the air volume and increases the VOC concentration, making the oxidation process in the RCO more fuel-efficient.
