Catalytic Oxidizer (RCO)
Noble metal catalysts oxidize VOCs to CO₂ and H₂O at 250-400 °C — significantly lower temperature and energy use compared to RTO incineration. MUSI Technology manufactures RCO systems in Changzhou, China, operating at about 400 °C with ≥97% VOC destruction, and supplies them together with the coating line as a single turnkey contract.
Best for medium airflow and medium concentration exhaust
RCO vs RTO: when a catalytic oxidizer is the right VOC control
A regenerative catalytic oxidizer (RCO) oxidises paint shop VOCs over a catalyst at a lower temperature than a thermal RTO, so it uses less fuel on low-concentration, steady exhaust such as flash-off zones and small spray booths. An RTO suits higher solvent loads and mixed exhaust; a catalytic oxidizer suits clean, low-load streams without catalyst poisons such as silicone or sulphur. Both use ceramic heat-recovery beds.
- Choose RCO when: solvent concentration is low and stable, exhaust is free of catalyst poisons, and fuel cost matters more than capital cost.
- Choose RTO when: solvent load is high or variable, paints contain silicone additives, or the line may switch paint systems later.
- Choose a zeolite rotor concentrator ahead of either when booth air volume is large.
RCO system price range
Indicative budget from our published cost guide: VOC treatment for solvent exhaust on a coating line is roughly USD 80,000-400,000, depending on air volume, VOC concentration and the technology chosen (RTO, RCO, zeolite rotor concentrator or activated carbon). This is a system-level range, not the price of a single unit.

Frequently Asked Questions
QQuestions buyers ask before ordering
quotation · price · lead time · installation · warranty
What information do you need to prepare a quotation?
Send part drawings or photos, the largest part size and weight, the material, the required output per shift, the paint or powder type and number of colours, and the available floor space, ceiling height and power or gas supply. MUSI engineers reply within 24 hours; a recommended configuration and quotation follow once your part data is complete.
How much does this equipment cost?
Budget depends on part size, throughput and the level of automation. Indicative ex-works ranges are published in our complete coating line cost guide; a configured quotation is prepared from your part data. Published indicative ex-works ranges: a complete powder coating line is roughly USD 75,000–230,000 semi-automatic, USD 200,000–600,000 for a standard automatic line and USD 600,000–2,000,000 for a high-throughput automated plant.
What is the lead time?
Standard configurations ship in 30–60 days from contract signing and down payment; custom configurations take longer. The delivery date is fixed in the contract.
Do you install and train operators overseas?
Yes. MUSI engineers carry out on-site installation and commissioning and give 3–5 days of operator and maintenance training. MUSI has delivered 800+ coating lines to customers in 36 countries.
What warranty and after-sales support are included?
12 months full-machine warranty, 36 months on critical components and up to 60 months on structural parts. International customers get 24-hour phone response and 72-hour on-site arrival; spare parts ship from the Changzhou headquarters.
Can the environmental equipment be supplied with the line?
Yes. VOC treatment (RTO, RCO, activated carbon, zeolite rotor), dust collection and paint wastewater treatment are supplied with the coating line under one contract; MUSI has equipped 50+ coating facilities whose projects all passed local environmental compliance reviews.
