Tire / Rubber


Numerous processes are utilized in tire production – from mixing the raw materials to the production and amalgamation of individual components to quality control. For the production of the various rubber mixtures, also called mixing, rubber is combined with different substances such as soot, silicon, oils, resin or sulfur and is mixed. In vulcanization, what is known as the baking process, the tire components are connected together using heat presses at over 170°C (340°F) and hardened. In these processing stages of tire production, large volume flows of odour emissions and rubber dust are produced, which get into the atmosphere and harm the environment. Riedel Filtertechnik offers a wide range of standardized and tailored solutions for this process exhaust air – from dust extraction to reduction of odour emissions. Our dedusting systems can be customized to specific requirements. They result in output significantly below the threshold of 10 mg/m³. That typical rubber smell? Our COPLAS clean system eliminates it by separating VOCs, such as ethanol, from the mixing room in an energy efficient and reliable way, thus making tire production more sustainable than with traditional technologies.
