Series Regenerative Catalytic Oxidizer\" \/><\/p>\n<h3>Product Overview<\/h3>\n<p>The RCO series regenerative catalytic oxidizer is specially designed for treating medium- to high-concentration industrial organic exhaust gas, typically within a VOC concentration range of approximately 1,000\u201310,000 mg\/m\u00b3.<\/p>\n<p>The system can also be integrated into an activated carbon adsorption concentration and catalytic combustion process, where it replaces the conventional catalytic combustion chamber and heating unit.<\/p>\n<p>RCO technology is particularly suitable for applications requiring a high heat recovery rate. It is also well suited to production lines where the exhaust gas composition changes frequently due to different products or where VOC concentrations fluctuate significantly.<\/p>\n<p>The system can treat a wide range of organic compounds, including aromatic hydrocarbons, ketones, esters, phenols, aldehydes, alcohols, ethers and other hydrocarbon-based pollutants.<\/p>\n<p>During treatment, the organic exhaust gas is heated to approximately 280\u00b0C or above. Under the action of the catalyst, VOCs are oxidized and decomposed into carbon dioxide and water vapor.<\/p>\n<p>The medium- to high-temperature gas generated during catalytic oxidation passes through the heat recovery section and transfers most of its thermal energy to the incoming exhaust gas. This reduces the fuel required to raise the inlet gas temperature and improves overall operating efficiency.<\/p>\n<p><!-- Image 2: RCO Working Principle Diagram --><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-1002 size-full\" src=\"https:\/\/www.esair-equip.com\/wp-content\/uploads\/2026\/08\/ca42897d-28c2-460f-a85f-9c84e2035485.png\" alt=\"Working Principle of Regenerative Catalytic Oxidizer\" width=\"1448\" height=\"1086\" srcset=\"https:\/\/www.esair-equip.com\/wp-content\/uploads\/2026\/08\/ca42897d-28c2-460f-a85f-9c84e2035485.png 1448w, https:\/\/www.esair-equip.com\/wp-content\/uploads\/2026\/08\/ca42897d-28c2-460f-a85f-9c84e2035485-300x225.png 300w, https:\/\/www.esair-equip.com\/wp-content\/uploads\/2026\/08\/ca42897d-28c2-460f-a85f-9c84e2035485-1024x768.png 1024w, https:\/\/www.esair-equip.com\/wp-content\/uploads\/2026\/08\/ca42897d-28c2-460f-a85f-9c84e2035485-768x576.png 768w\" sizes=\"auto, (max-width: 1448px) 100vw, 1448px\" \/><\/p>\n<h3>Working Principle<\/h3>\n<p>Organic exhaust gas is drawn into the oxidation system by a centrifugal fan. The gas is heated by the burner or auxiliary heating system until it reaches an operating temperature of approximately 250\u2013300\u00b0C.<\/p>\n<p>At this temperature, the organic compounds in the exhaust gas pass through the catalyst bed and are oxidized into carbon dioxide and water.<\/p>\n<p>The high-temperature treated gas then enters a specially designed ceramic heat-storage chamber. More than 95% of the thermal energy can be absorbed and stored by the ceramic media under suitable operating conditions.<\/p>\n<p>After transferring its heat to the ceramic media, the treated gas temperature drops to a level close to the inlet gas temperature and is discharged through the exhaust stack.<\/p>\n<p>A regenerative catalytic oxidation system normally consists of two or three heat-storage chambers. Under PLC control, the gas flow direction is switched periodically so that the system continuously completes preheating, catalytic oxidation, heat storage and purging.<\/p>\n<p>First, untreated exhaust gas enters a previously heated heat-storage chamber. The ceramic media transfers stored heat to the incoming gas, raising its temperature before it enters the catalytic oxidation chamber.<\/p>\n<p>After oxidation, the purified high-temperature gas passes through another heat-storage chamber, where it releases thermal energy to the ceramic media before being discharged.<\/p>\n<p>In a three-chamber system, a portion of the purified gas is directed into the third chamber to purge any residual untreated exhaust gas. This helps prevent untreated gas from being discharged during valve switching.<\/p>\n<p>For applications with less stringent pollutant removal requirements, a two-chamber configuration may be selected to reduce equipment investment.<\/p>\n<h3>Operating Process<\/h3>\n<table border=\"1\" width=\"100%\" cellspacing=\"0\" cellpadding=\"10\">\n<tbody>\n<tr>\n<td><strong>Process Stage<\/strong><\/td>\n<td><strong>Description<\/strong><\/td>\n<\/tr>\n<tr>\n<td><strong>1.

The catalyst may contain precious metals or transition metals selected according to the pollutant composition and operating requirements.<\/p>\n<p>Because the catalyst lowers the activation energy required for VOC oxidation, organic pollutants can be decomposed at approximately 250\u2013500\u00b0C instead of the much higher temperatures required for direct thermal oxidation.<\/p>\n<p>This reduces fuel consumption, decreases equipment thermal load and helps lower the overall investment and operating costs.<\/p>\n<h3>Waste Heat Recovery<\/h3>\n<p>The high-temperature gas produced after catalytic oxidation contains recoverable thermal energy. In addition to regenerative heat recovery inside the RCO system, optional heat exchangers can be installed to supply hot air or hot water to other production processes.<\/p>\n<p>Recovered heat can be reused in drying ovens, coating lines, production heating systems or other processes requiring thermal energy.<\/p>\n<p>For facilities with drying lines, recovering the oxidation heat can significantly reduce overall energy consumption.<\/p>\n<h3>Applicable Industries<\/h3>\n<ul>\n<li>Automotive coating production lines<\/li>\n<li>Shipbuilding and marine coating operations<\/li>\n<li>Motorcycle and bicycle manufacturing<\/li>\n<li>Household appliance production<\/li>\n<li>Container coating and drying lines<\/li>\n<li>Petroleum and petrochemical industries<\/li>\n<li>Chemical manufacturing<\/li>\n<li>Rubber product production<\/li>\n<li>Paint and coating manufacturing<\/li>\n<li>Shoe adhesive and bonding processes<\/li>\n<li>Plastic product manufacturing<\/li>\n<li>Metal printing and can manufacturing<\/li>\n<li>Printing ink production and printing lines<\/li>\n<li>Cable and enameled wire production<\/li>\n<li>Industrial drying lines requiring heat recovery<\/li>\n<\/ul>\n<p><!-- Image 4: Industrial Project or Application Site --><\/p>\n<p><img decoding=\"async\" src=\"YOUR-IMAGE-URL-4\" alt=\"Industrial Application of Regenerative Catalytic Oxidizer\" \/><\/p>\n<h3>Typical Treatable Organic Compounds<\/h3>\n<table border=\"1\" width=\"100%\" cellspacing=\"0\" cellpadding=\"10\">\n<tbody>\n<tr>\n<td><strong>Compound Category<\/strong><\/td>\n<td><strong>Typical Examples<\/strong><\/td>\n<\/tr>\n<tr>\n<td>Aromatic Hydrocarbons<\/td>\n<td>Benzene, toluene, xylene and related aromatic compounds<\/td>\n<\/tr>\n<tr>\n<td>Ketones<\/td>\n<td>Acetone, methyl ethyl ketone and other ketone compounds<\/td>\n<\/tr>\n<tr>\n<td>Esters<\/td>\n<td>Ethyl acetate, butyl acetate and other ester solvents<\/td>\n<\/tr>\n<tr>\n<td>Phenols<\/td>\n<td>Phenol and related phenolic compounds<\/td>\n<\/tr>\n<tr>\n<td>Aldehydes<\/td>\n<td>Formaldehyde and other aldehyde compounds<\/td>\n<\/tr>\n<tr>\n<td>Alcohols<\/td>\n<td>Ethanol, methanol, isopropanol and other alcohol vapors<\/td>\n<\/tr>\n<tr>\n<td>Ethers<\/td>\n<td>Ether-based organic solvents<\/td>\n<\/tr>\n<tr>\n<td>Hydrocarbons<\/td>\n<td>Mixed hydrocarbon vapors and petroleum-based VOCs<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3>Operating Cost Advantages<\/h3>\n<p>When the organic exhaust gas concentration reaches a sufficient level, typically around 1,000 mg\/m\u00b3 or higher depending on its calorific value, the oxidation heat released by the VOCs can help maintain the required operating temperature.<\/p>\n<p>Under suitable conditions, the auxiliary heating system may operate intermittently or stop after startup, significantly reducing fuel consumption.<\/p>\n<p>The actual self-sustaining concentration depends on VOC composition, airflow, heating value, moisture content, heat recovery efficiency and system heat loss.<\/p>\n<h3>Safety and Automatic Control<\/h3>\n<ul>\n<li>Automatic temperature control<\/li>\n<li>High-temperature alarm and shutdown protection<\/li>\n<li>Fan and valve interlock control<\/li>\n<li>Combustion flame monitoring<\/li>\n<li>Overpressure and abnormal pressure alarm<\/li>\n<li>PLC-controlled chamber switching<\/li>\n<li>Automatic purging before startup and flow switching<\/li>\n<li>Emergency shutdown protection<\/li>\n<li>Optional VOC concentration and LEL monitoring<\/li>\n<\/ul>\n<h3>Important Operating Requirements<\/h3>\n<p>Before selecting and operating the RCO system, the exhaust gas composition and installation environment must be carefully evaluated.<\/p>\n<h4>Unsuitable or Restricted Substances<\/h4>\n<ul>\n<li>Highly viscous oil or ester-like substances that may coat the catalyst surface<\/li>\n<li>Phosphorus-containing compounds<\/li>\n<li>Arsenic-containing compounds<\/li>\n<li>Antimony compounds<\/li>\n<li>Mercury compounds<\/li>\n<li>Lead compounds<\/li>\n<li>Zinc compounds<\/li>\n<li>Tin compounds<\/li>\n<li>High concentrations of dust or particulate matter<\/li>\n<\/ul>\n<p>These substances may poison, block or damage the catalyst and must be removed through appropriate pretreatment before the gas enters the RCO system.<\/p>\n<h4>Installation Environment<\/h4>\n<ul>\n<li>The installation area should be free from highly corrosive gases.<\/li>\n<li>Outdoor equipment should be provided with effective rain protection.<\/li>\n<li>Adequate maintenance and emergency access should be reserved.<\/li>\n<li>The installation foundation should meet the equipment load requirements.<\/li>\n<li>Ventilation and fire-safety requirements should be evaluated before installation.<\/li>\n<\/ul>\n<h4>Electrical Supply<\/h4>\n<p>The standard electrical requirement stated for the equipment is three-phase AC 380 V, 50 Hz.

It oxidizes organic pollutants at a relatively low temperature and reuses the heat from the treated gas.<\/p>\n<h4>What VOC concentration is suitable for the RCO series?<\/h4>\n<p>The RCO series is generally designed for medium- to high-concentration organic exhaust gas, typically around 1,000\u201310,000 mg\/m\u00b3. The final suitability depends on VOC composition, airflow and calorific value.<\/p>\n<h4>What is the difference between RCO and RTO?<\/h4>\n<p>RCO uses a catalyst to reduce the required oxidation temperature, while RTO relies on higher-temperature thermal oxidation. RCO can reduce fuel consumption but requires stricter pretreatment to protect the catalyst.<\/p>\n<h4>Can the RCO operate without continuous auxiliary heating?<\/h4>\n<p>Under suitable VOC concentration and calorific-value conditions, the oxidation heat released by the exhaust gas may maintain the required operating temperature after startup, reducing or eliminating continuous auxiliary heating.<\/p>\n<h4>Why is catalyst protection important?<\/h4>\n<p>Dust, heavy metals, phosphorus compounds, sticky oil mist and other contaminants may poison or block the catalyst. Suitable pretreatment is required to maintain catalytic activity and service life.<\/p>\n<h4>Can waste heat be reused?<\/h4>\n<p>Yes. Optional heat recovery equipment can use the treated gas heat for drying lines, process hot air, hot water or other production requirements.<\/p>\n<h4>Can ES Air customize the RCO system?<\/h4>\n<p>Yes. ES Air can design the system according to airflow, VOC concentration, chemical composition, temperature, humidity, dust content, heat recovery requirements and local emission standards.<\/p>\n<h3>Customized Regenerative Catalytic Oxidation Solutions<\/h3>\n<p>ES Air provides regenerative catalytic oxidation systems and integrated VOC treatment solutions for coating, chemical, printing, rubber, cable and industrial drying applications.<\/p>\n<p>System selection should be based on exhaust gas volume, VOC concentration, pollutant composition, calorific value, temperature, humidity, particulate content and required treatment efficiency.<\/p>\n<p>Contact ES Air for working-condition evaluation, process design, equipment selection and customized RCO solutions.<\/p>\n<p style=\"margin-top: 30px;\"><em><br \/>\nSEO Brief: The ES Air RCO Series Regenerative Catalytic Oxidizer is designed for medium- to high-concentration industrial VOC exhaust gas.

Catalytic Oxidizer (RCO Series)<\/h2>\r\n<!-- Image 1: Product Main Image -->\r\n\r\n<img src=\"YOUR-IMAGE-URL-1\" alt=\"RCO Series Regenerative Catalytic Oxidizer\" \/>\r\n<h3>Product Overview<\/h3>\r\nThe RCO series regenerative catalytic oxidizer is specially designed for treating medium- to high-concentration industrial organic exhaust gas, typically within a VOC concentration range of approximately 1,000\u201310,000 mg\/m\u00b3.\r\n\r\nThe system can also be integrated into an activated carbon adsorption concentration and catalytic combustion process, where it replaces the conventional catalytic combustion chamber and heating unit.\r\n\r\nRCO technology is particularly suitable for applications requiring a high heat recovery rate. It is also well suited to production lines where the exhaust gas composition changes frequently due to different products or where VOC concentrations fluctuate significantly.\r\n\r\nThe system can treat a wide range of organic compounds, including aromatic hydrocarbons, ketones, esters, phenols, aldehydes, alcohols, ethers and other hydrocarbon-based pollutants.\r\n\r\nDuring treatment, the organic exhaust gas is heated to approximately 280\u00b0C or above. Under the action of the catalyst, VOCs are oxidized and decomposed into carbon dioxide and water vapor.\r\n\r\nThe medium- to high-temperature gas generated during catalytic oxidation passes through the heat recovery section and transfers most of its thermal energy to the incoming exhaust gas. This reduces the fuel required to raise the inlet gas temperature and improves overall operating efficiency.\r\n\r\n<!-- Image 2: RCO Working Principle Diagram -->\r\n\r\n<img class=\"alignnone wp-image-1002 size-full\" src=\"https:\/\/www.esair-equip.com\/wp-content\/uploads\/2026\/08\/ca42897d-28c2-460f-a85f-9c84e2035485.png\" alt=\"Working Principle of Regenerative Catalytic Oxidizer\" width=\"1448\" height=\"1086\" \/>\r\n<h3>Working Principle<\/h3>\r\nOrganic exhaust gas is drawn into the oxidation system by a centrifugal fan. The gas is heated by the burner or auxiliary heating system until it reaches an operating temperature of approximately 250\u2013300\u00b0C.\r\n\r\nAt this temperature, the organic compounds in the exhaust gas pass through the catalyst bed and are oxidized into carbon dioxide and water.\r\n\r\nThe high-temperature treated gas then enters a specially designed ceramic heat-storage chamber. More than 95% of the thermal energy can be absorbed and stored by the ceramic media under suitable operating conditions.\r\n\r\nAfter transferring its heat to the ceramic media, the treated gas temperature drops to a level close to the inlet gas temperature and is discharged through the exhaust stack.\r\n\r\nA regenerative catalytic oxidation system normally consists of two or three heat-storage chambers. Under PLC control, the gas flow direction is switched periodically so that the system continuously completes preheating, catalytic oxidation, heat storage and purging.\r\n\r\nFirst, untreated exhaust gas enters a previously heated heat-storage chamber. The ceramic media transfers stored heat to the incoming gas, raising its temperature before it enters the catalytic oxidation chamber.\r\n\r\nAfter oxidation, the purified high-temperature gas passes through another heat-storage chamber, where it releases thermal energy to the ceramic media before being discharged.\r\n\r\nIn a three-chamber system, a portion of the purified gas is directed into the third chamber to purge any residual untreated exhaust gas. This helps prevent untreated gas from being discharged during valve switching.\r\n\r\nFor applications with less stringent pollutant removal requirements, a two-chamber configuration may be selected to reduce equipment investment.\r\n<h3>Operating Process<\/h3>\r\n<table border=\"1\" width=\"100%\" cellspacing=\"0\" cellpadding=\"10\">\r\n<tbody>\r\n<tr>\r\n<td><strong>Process Stage<\/strong><\/td>\r\n<td><strong>Description<\/strong><\/td>\r\n<\/tr>\r\n<tr>\r\n<td><strong>1.

The catalyst may contain precious metals or transition metals selected according to the pollutant composition and operating requirements.\r\n\r\nBecause the catalyst lowers the activation energy required for VOC oxidation, organic pollutants can be decomposed at approximately 250\u2013500\u00b0C instead of the much higher temperatures required for direct thermal oxidation.\r\n\r\nThis reduces fuel consumption, decreases equipment thermal load and helps lower the overall investment and operating costs.\r\n<h3>Waste Heat Recovery<\/h3>\r\nThe high-temperature gas produced after catalytic oxidation contains recoverable thermal energy. In addition to regenerative heat recovery inside the RCO system, optional heat exchangers can be installed to supply hot air or hot water to other production processes.\r\n\r\nRecovered heat can be reused in drying ovens, coating lines, production heating systems or other processes requiring thermal energy.\r\n\r\nFor facilities with drying lines, recovering the oxidation heat can significantly reduce overall energy consumption.\r\n<h3>Applicable Industries<\/h3>\r\n<ul>\r\n \t<li>Automotive coating production lines<\/li>\r\n \t<li>Shipbuilding and marine coating operations<\/li>\r\n

higher depending on its calorific value, the oxidation heat released by the VOCs can help maintain the required operating temperature.\r\n\r\nUnder suitable conditions, the auxiliary heating system may operate intermittently or stop after startup, significantly reducing fuel consumption.\r\n\r\nThe actual self-sustaining concentration depends on VOC composition, airflow, heating value, moisture content, heat recovery efficiency and system heat loss.\r\n<h3>Safety and Automatic Control<\/h3>\r\n<ul>\r\n \t<li>Automatic temperature control<\/li>\r\n \t<li>High-temperature alarm and shutdown

It is also well suited to production lines where the exhaust gas composition changes frequently due to different products or where VOC concentrations fluctuate significantly.\r\n\r\nThe system can treat a wide range of organic compounds, including aromatic hydrocarbons, ketones, esters, phenols, aldehydes, alcohols, ethers and other hydrocarbon-based pollutants.\r\n\r\nDuring treatment, the organic exhaust gas is heated to approximately 280\u00b0C or above. Under the action of the catalyst, VOCs are oxidized and decomposed into carbon dioxide and water vapor.\r\n\r\nThe medium- to high-temperature gas generated during catalytic oxidation passes through the heat recovery section and transfers most of its thermal energy to the incoming exhaust gas. This reduces the fuel required to raise the inlet gas temperature and improves overall operating efficiency.\r\n\r\n<!-- Image 2: RCO Working Principle Diagram -->\r\n\r\n<img class=\"alignnone wp-image-1002 size-full\" src=\"https:\/\/www.esair-equip.com\/wp-content\/uploads\/2026\/08\/ca42897d-28c2-460f-a85f-9c84e2035485.png\" alt=\"Working Principle of Regenerative Catalytic Oxidizer\" width=\"1448\" height=\"1086\" \/>\r\n<h3>Working Principle<\/h3>\r\nOrganic exhaust gas is drawn into the oxidation system by a centrifugal fan. The gas is heated by the burner or auxiliary heating system until it reaches an operating temperature of approximately 250\u2013300\u00b0C.\r\n\r\nAt this temperature, the organic compounds in the exhaust gas pass through the catalyst bed and are oxidized into carbon dioxide and water.\r\n\r\nThe high-temperature treated gas then enters a specially designed ceramic heat-storage chamber. More than 95% of the thermal energy can be absorbed and stored by the ceramic media under suitable operating conditions.\r\n\r\nAfter transferring its heat to the ceramic media, the treated gas temperature drops to a level close to the inlet gas temperature and is discharged through the exhaust stack.\r\n\r\nA regenerative catalytic oxidation system normally consists of two or three heat-storage chambers. Under PLC control, the gas flow direction is switched periodically so that the system continuously completes preheating, catalytic oxidation, heat storage and purging.\r\n\r\nFirst, untreated exhaust gas enters a previously heated heat-storage chamber. The ceramic media transfers stored heat to the incoming gas, raising its temperature before it enters the catalytic oxidation chamber.\r\n\r\nAfter oxidation, the purified high-temperature gas passes through another heat-storage chamber, where it releases thermal energy to the ceramic media before being discharged.\r\n\r\nIn a three-chamber system, a portion of the purified gas is directed into the third chamber to purge any residual untreated exhaust gas. This helps prevent untreated gas from being discharged during valve switching.\r\n\r\nFor applications with less stringent pollutant removal requirements, a two-chamber configuration may be selected to reduce equipment investment.\r\n<h3>Operating Process<\/h3>\r\n<table border=\"1\" width=\"100%\" cellspacing=\"0\" cellpadding=\"10\">\r\n<tbody>\r\n<tr>\r\n<td><strong>Process Stage<\/strong><\/td>\r\n<td><strong>Description<\/strong><\/td>\r\n<\/tr>\r\n<tr>\r\n<td><strong>1.

The catalyst may contain precious metals or transition metals selected according to the pollutant composition and operating requirements.\r\n\r\nBecause the catalyst lowers the activation energy required for VOC oxidation, organic pollutants can be decomposed at approximately 250\u2013500\u00b0C instead of the much higher temperatures required for direct thermal oxidation.\r\n\r\nThis reduces fuel consumption, decreases equipment thermal load and helps lower the overall investment and operating costs.\r\n<h3>Waste Heat Recovery<\/h3>\r\nThe high-temperature gas produced after catalytic oxidation contains recoverable thermal energy. In addition to regenerative heat recovery inside the RCO system, optional heat exchangers can be installed to supply hot air or hot water to other production processes.\r\n\r\nRecovered heat can be reused in drying ovens, coating lines, production heating systems or other processes requiring thermal energy.\r\n\r\nFor facilities with drying lines, recovering the oxidation heat can significantly reduce overall energy consumption.\r\n<h3>Applicable Industries<\/h3>\r\n<ul>\r\n \t<li>Automotive coating production lines<\/li>\r\n \t<li>Shipbuilding and marine coating operations<\/li>\r\n
