Efficient Air Pollution Control in Surface Treatment 

Significant volumes of volatile organic compounds are generated during the printing and drying in flexographic and rotogravure operations. To treat exhaust air from printing flexible packaging, labels, cigarette paper, banknotes, wallpaper, and specialty substrates – as well as heatset web offset printing and screen printing lines – Envanio offers proven RTO systems compatible with both individual presses and plant-wide exhaust headers. 

Roll-to-roll processes such as coating, laminating, lacquering, and bonding releases high solvent loads because the entire web surface is treated. Applications involving plastic films, aluminum foils, adhesive labels, decorative laminates, and technical textiles provide ideal conditions for the autothermal operation of our regenerative thermal oxidizers (RTO). Through multi-stage energy recovery, a large portion of the heat contained in the exhaust air can be harnessed for production processes or plant utilities, transforming the abatement system from an energy consumer into an energy supplier.  

Printing and coating metal substrates presents distinct air pollutions control challenges, as specialty lacquers, overspray particulates, and high-temperature curing ovens require tailored filtration and abatement. For the production of beverage and food cans, collapsible tubes, drums, and continuous coil coating lines, Envanio designs rugged RTO systems that ensure efficient, reliable air purification under demanding operating conditions. 

Coating molded and structural parts in spray booths generates high volumes of exhaust air with low VOC concentrations. For cost-effective treatment, Envanio pairs adsorptive VOC concentration systems (rotor concentrators) with recuperative or regenerative thermal oxidizers. This configuration efficiently treats air volumes exceeding several 100,000 m³/h for automotive suppliers and manufacturers of furniture, plastics, household appliances, and wind turbine towers. 

Our systems are designed to handle a wide range of industrial emissions, from volatile organic compounds (VOCs) and solvent vapors to strong odors and complex mixtures of organic pollutants. When selecting the appropriate system design, we tailor our approach directly to the requirements of your chemical processes.

Exhaust air treatment failure can lead to unplanned production shutdowns, compliance risks, and significant costs. That is why Envanio places special emphasis on robust system design, heavy-duty manufacturing quality, and comprehensive service throughout the entire equipment lifecycle.

By tailoring exhaust treatment to each specific process and using energy-efficient system designs, Envanio helps optimize your energy consumption operating costs. Integrating heat recovery – or, where applicable, acid recovery – and recirculating these resources back into production significantly increases overall cost-effectiveness.
