Tire production / Rubber


Tire production involves numerous processes – from the mixing of the basic materials to the production and combination of individual components to quality control. Depending on the mixture, rubber, for example, is mixed with carbon black, silica, oils, resins and sulphur to produce the various rubber mixtures, also known as mixing. During vulcanisation, or baking, the tire components are bonded together using heating presses at over 170°C and cured. During these processing steps in tire production, large volume flows are loaded with odour emissions and rubber dusts that are released into the atmosphere and pollute the environment.

Riedel Filtertechnik offers a wide range of standard and individual solutions for these process exhaust air flows – from dedusting applications to rubber odour control. 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. It eliminates typical rubber odours by separating VOCs, such as ethanol. So, tire production can become more sustainable than with conventional technologies.

Riedel's experienced personnel will ensure trouble-free installation and commissioning of your system at your site – mechanical and electrical assembly combined. We would be happy to accompany you during subsequent official acceptance measurements.


We are there to help you with any questions you may have and are your long-term partner when it comes to maintenance & repair, optimization & upgrade and spare parts.


  • Fabric filters

    Our dedusting solutions can achieve clean gas dust contents below 1.0 mg/m³ as standard. Furthermore, in many cases, the air can be fed back into production. The result is that dust emissions are reduced by using fabric filters and we play our part in taking care of our environment. Our JMS hose filters, JMP cartridge filters and JMT bag filters are cleaned automatically with compressed air. These dedusting solutions are also available in stainless steel, with pressure shock resistance, trace heating and insulation as well as fire and explosion protection. We have the expertise to find the right type of industrial fabric filter for your production requirements.

  • Venturi & absorption scrubbers

    Venturi scrubbers are a proven, industry wide solution for air pollution control. Our HNA venturi scrubber can reliably remove dust from damp exhaust air flows. This wet scrubber is designed to clean gas dust content of below 5.0 mg/m³ with reasonable energy expenditure. The scrubbing liquid is treated and cleaned via automatic belt filters or time-controlled outlet valves, which empty automatically during the operation of a partial load. The absorption scrubber reduces acidic and basic as well as gas-laden components in the exhaust air to the permissible values.

  • COPLAS clean – Odour reduction with cold plasma

    Our cold plasma treatment eliminates odours just like nature, only faster. COPLAS clean is our non-thermal plasma technology for industrial odour control. Odours are eradicated without any chemicals, water or waste. Our patented plasma reactors produce reactive oxygen and OH radicals, which are then injected into the exhaust air. The ingenious result is that odour molecules are oxidised in just milliseconds by non-thermal plasma technology – without any direct contact with your systems.

  • Pneumatic transport

    Bulk materials such as cut tobacco, tea, chips or crystal sugar are transported gently with our pneumatic transport system to keep production changes to an absolute minimum. Our patented SACU tobtronic® is the most effective and safest technology to ensure blockage-free, pneumatic conveying of bulk materials at a low speed. The patented FPC pipe couplings avoid gaps and edges that can affect the bulk material.

  • VAC & NetVac® – Industrial central vacuum cleaning systems

    Our industrial central vacuum cleaning systems improve the working conditions of your employees, increase plant availability and reduce wear and tear. Industrial central vacuum cleaning systems are more efficient than mobile industrial vacuum cleaners. These central vacuum cleaning systems ensure that any removed material, such as dust, bulk material or production residues, are collected in a central location. As a result, waste disposal is much simpler. There is no limit to the number of cleaning points that can be installed.

  • Central dust and material handling – industrial dust collection system

    A central industrial dust collector enhances the efficiency and cleanliness of machines, systems and buildings. Our dust collector systems consolidate bulk materials, dusts or products at central locations. When the dust collection system is in suction operation, the bulk material is automatically taken from the collection points and then transported over long distances. At the receiving point, the product is sent for further processing, loaded or compacted for disposal.
