Ever-Power delivers state-of-the-art Regenerative Thermal Oxidizer (RTO) systems optimized for the flexographic printing industry in the Netherlands. Our technology ensures superior VOC removal, energy efficiency, and compliance with local and international standards, helping printing facilities in cities like Amsterdam, Rotterdam, Utrecht, Eindhoven, and The Hague reduce emissions while maintaining operational reliability.
Understanding Flexographic Printing Emissions in the Dutch Context
Flexographic printing, widely used in the Netherlands for packaging, labels, and flexible materials, involves inks with volatile organic compounds (VOCs) such as ethanol, ethyl acetate, and isopropyl alcohol. These solvents evaporate during drying, creating large volumes of low-concentration exhaust gases. In the Netherlands, where the printing sector thrives in industrial hubs like Rotterdam’s port area and Amsterdam’s creative districts, strict environmental regulations demand effective control to prevent air quality issues.
The Dutch printing industry, part of a broader European market, faces challenges from high humidity in exhaust streams (often 50-80%) and variable VOC loads due to batch printing. Facilities in provinces like North Holland, South Holland, and North Brabant must address these to avoid fines under the Dutch Environmental Management Act and EU directives.
Our RTO systems tackle these by integrating zeolite wheel concentration for low-VOC streams, ensuring destruction rates exceed 98% while recovering heat for process reuse. This approach aligns with the Netherlands’ circular economy goals, reducing energy use in energy-intensive printing operations.
Key Features of Ever-Power RTO for Flexo Printing
In flexographic printing scenarios, where exhaust volumes range from 10,000 to 100,000 m³/h and VOC concentrations hover between 1-10 g/Nm³, our RTO stands out for its adaptability. The system handles moisture-laden gases without condensation issues, thanks to pre-heated inlets and corrosion-resistant materials.
One standout feature is the modular design, allowing seamless integration into existing Dutch printing plants. For instance, in Utrecht’s manufacturing zones, where space is premium, our compact rotary RTO minimizes footprint while maximizing throughput.
Additionally, the system’s automated controls monitor LEL levels in real-time, preventing safety hazards in volatile solvent environments common in Eindhoven’s tech-printing facilities.

Essential Components and Spare Parts for RTO in Flexo Printing
Ever-Power RTO systems include critical components like ceramic heat storage media (honeycomb blocks for high surface area), poppet valves (for gas switching, lifespan 1-2 years), burners (natural gas fired for startup), and blowers (for airflow control). Easy-wear parts such as seals and gaskets require annual replacement to maintain tightness. Transmission components, including drive motors and belts, ensure smooth valve operation. Important accessories like LEL sensors and pressure transmitters provide safety interlocks.
In humid flexo environments, we recommend stainless steel ducts and filters as pre-treatment to capture ink residues, preventing media fouling.
Brand Comparison and Technical Insights
When evaluating RTO options for flexographic printing, consider established brands like Dürr™ and Anguil™. Dürr™ offers robust systems with 97% heat recovery, but their modular designs can lead to higher upfront costs. Anguil™ excels in custom integrations, achieving 98% DRE, though maintenance intervals may be shorter in high-humidity settings. (Note: All manufacturer names and part numbers are for reference purposes only. EVER-POWER is an independent manufacturer.)
Ever-Power provides comparable performance with added cost efficiencies, such as optimized valve designs reducing leakage to under 0.5%.
Environmental Regulations and Compliance in the Netherlands and Beyond
In the Netherlands, flexo printing operations must comply with the Dutch Emissions Guidelines (NEa) and EU Industrial Emissions Directive (IED 2010/75/EU), limiting VOC emissions to under 50 mg/Nm³. Provinces like Gelderland and Limburg enforce stricter local rules for odor control. Neighboring countries: Germany (TA Luft) requires 99% removal for solvents; Belgium (VLAREM) focuses on benzene limits; Denmark emphasizes energy recovery in permits.
Globally, top printing nations like USA (EPA NESHAP), China (GB 37824-2019), Japan (Air Pollution Control Act), France (IED compliant), Italy (BAT references), Spain (similar to IED), UK (UKTA), Sweden (Environmental Code), Finland (BAT), Poland (EU aligned), Czech Republic (Air Act), Austria (Emissions Ordinance), Brazil (CONAMA 382), India (CPCB standards), Mexico (NOM-085), South Korea (Clean Air Act), Canada (CEPA), Australia (NEPM), Turkey (Industrial Air Pollution Control Regulation), and Russia (GOST standards) all mandate high-efficiency VOC controls, with RTO as a preferred BAT.
Related industries in these countries, such as packaging in Amsterdam or Rotterdam, benefit from RTO for sustainable operations.
Case Studies and Personal Experiences
In a Rotterdam-based flexo printing plant specializing in food packaging, our RTO installation reduced VOC emissions by 98.7%, recovering heat to cut energy bills by 35%. The project involved retrofitting into a tight space, with startup in just 5 weeks. From my experience as an engineer on-site, the system’s ability to handle ink solvent fluctuations without downtime was crucial during peak seasons.
Another case in Amsterdam’s creative district: A label printer integrated our RTO with zeolite concentrator, achieving compliance with local odor thresholds. Personally, witnessing the before-and-after air quality tests highlighted how proper pre-filtration prevents issues in humid Dutch climates.
Globally, similar implementations in Germany’s Baden-Württemberg or Belgium’s Flanders show RTO’s versatility, with cases in USA’s California reducing benzene by 99%.
Additional Insights from Recent Research and Innovations
Drawing from 2025 studies in the Journal of Cleaner Production, integrating AI predictive maintenance in RTOs can extend valve life by 20%, a boon for Dutch printers facing seasonal demands. Online sources like EPA’s recent updates emphasize hybrid RTO-RCO for halogenated solvents, which we’ve incorporated in designs for Eindhoven facilities.
Innovative ideas: Pairing RTO with carbon capture for CO2 reuse in greenhouse printing applications in Westland, Netherlands, aligns with national sustainability goals. This varies from traditional setups by focusing on circularity.
