We test the applicability and efficiency of COPLAS clean for reducing process-specific odours.

On-site Customizing


Because customer satisfaction is important to us, we offer you a customer-specific solution through a system tailored to you. To achieve this, we carry out customization with our COPLAS clean mobile unit on site at your premises. First, we record all relevant operating data, official requirements and local conditions. The requirements for customization are minimal. We merely need access to outside air, an extraction point in the exhaust duct and a power connection.

COPLAS clean

Advantages for you

  • Check of applicability
  • Check of efficiency
  • Low financial risk
  • Optimized energy consumption
  • Official and robust results for the authorities for measurements with a laboratory

Procedure of our Customizing

  • Connection: Flexible aluminum hoses are connected to the exhaust air
  • Exhaust air: 100 m³/h exhaust air is extracted
  • Adjustment: Different power outputs to determine the necessary power output of a possible overall system
  • Samples: Taken before and after cold plasma treatment
  • Analysis: Unofficial results – performed in-house – or official results – olfactometry by a certified and independent olfactory laboratory is recommended


  • Tire / Rubber

    Riedel Filtertechnik offers a wide range of standard and individual solutions for process exhaust in tire production – from dust extraction to odour emission reduction. Our specially designed dust extraction systems keep emissions well below the limit values of 10 mg/m³. That typical smell of rubber is eliminated by our COPLAS clean cold plasma air cleaner system in an energy-efficient and reliable way. So, tire production can become more sustainable than with conventional technologies.

  • Food

    Cereals, oil or milk powder – food production is characterised by the variety of food products alone. Countless process steps including extrusion, drying, cooling or product packaging are completed for their production. As a result, dust or strong-smelling odour emissions are inevitably released into the environment and are subject to strict limits. We help our customers to comply with these emission limits by offering a wide range of products – from dust removal to industrial odour control systems.

  • Pet food

    Pet food production involves numerous process steps – extrusion, drying, cooling, machine extraction or even wet food cooking. During the processing of wet and dry pet food, dusts and odorous substances are released into the exhaust air, which can pollute the environment. Riedel Filtertechnik offers a wide product portfolio with individual solutions for pet food production. We cover everything from dust extraction and dedusting of conveyors, extruders and dryers to the reduction of odour emissions.

  • Compound feed

    In compound feed production, odour-intensive substances are often added for specific recipes. As a consequence, odour emissions are produced that can pollute the environment. Grinding fine, dry ingredients and pelleting also produces dust emissions, which can be controlled using our filter systems. Our COPLAS clean cold plasma technology for air cleaning reduces any odours sustainably without any chemicals or waste products.
