ChaoriIndustrial Catalytic Oxidizer

SHARE
The industrial catalytic oxidizer from Chaori Environment is a pivotal solution for the efficient control of volatile organic compounds (VOCs) across diverse industries like printing, chemical manufacturing, food processing, and electronics. This system is engineered to achieve VOC destruction at significantly lower temperatures (250-450°C) compared to traditional thermal oxidizers, leading to up to 60% savings in fuel consumption. The system employs advanced precious-metal honeycomb catalyst technology to ensure high destruction efficiency of ≥99% with an extended catalyst lifespan. Equipped with a recuperative heat exchanger, it captures 70-80% of exhaust energy, effectively pre-heating incoming air, thereby further reducing auxiliary fuel needs. Its compact, skid-mounted design is space-efficient and facilitates quick installation. Additionally, smart PLC systems offer remote monitoring and process optimization, ensuring operational reliability and easy maintenance. The low operating temperatures also minimize NOx emissions, achieving <50 mg/Nm³ without the need for additional control systems.
