A packed bed scrubber, also called a packed tower scrubber or packed column scrubber is a wet scrubber or gas scrubber designed to remove gaseous contaminants from airflows. This form of gas absorber can capture and neutralise any poisonous or dangerous gases from air streams and then expel clean air back out into the atmosphere. Our packed bed scrubbers reduce many pollutant components in exhaust air, including hydrocarbons, alcohols, ammonia, amines or hydrogen sulphide to the permissible limits. By combining an upstream packed bed scrubber with subsequent cold plasma treatment, VOC and odour concentration in the exhaust air can be effectively reduced.
- Effective VOC and odour reduction
- Compliance with permissible limits
- Reliable continuous operation
- Low water consumption
- Low maintenance and spare parts requirements
- 24/7 operation
- Scrubbing liquid recirculation
- Automatic dosage
- Automatic partial discharge
- Trace heating for outdoor installation
- Effective combination with COPLAS clean cold plasma technology
- 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.
We have been an innovative partner to the tobacco industry for over 50 years. We are established worldwide as a system supplier of exhaust air purification and industrial odour reduction systems in the manufacturing of cigarettes. Our pneumatic transport systems, central vacuum cleaning systems and machine cleaning systems are designed to achieve our main goals: environmental protection, energy efficiency and increased yield in the tobacco industry. We continue to innovate in the primary and secondary sectors with effective and patented technologies.
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.
