If your exhaust air flows are damp and contaminated with gases, our venturi scrubber will clean them safely and efficiently.

Venturi scrubbers

Exhaust air cleaning

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 for clean gas dust contents 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.

Markets

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.
