Absorption scrubbers – the solution to safely clean damp and contaminated exhaust air.
VOC abatement & odour control
Absorption Scrubber
An absorption scrubber is used to remove pollutant-laden components from industrial exhaust air, such as hydrocarbons, alcohols, ammonia, amines, or hydrogen sulfide. Due to the use of packed bed media and wash liquid for exhaust air cleaning, absorption scrubbers are also known as packed bed scrubbers and fall into the category of wet scrubbers. By combining an absorption scrubber with subsequent air purification using our patented COPLAS clean plasma technology, volatile organic compounds (VOCs) and odour concentrations in the exhaust air can be effectively reduced to permissible limit values.
Advantages & Features
Industrial Exhaust Air Cleaning Using Absorption Scrubbers
Absorption scrubbers are a proven and reliable technology for reducing VOCs, pollutants, and odours in industrial exhaust air. Discover the benefits of a packed bed scrubber for your application:
Effective VOC Reduction
Reliable removal of VOCs, pollutants, and odours in industrial exhaust air. Elimination of pollutant-laden components through the use of wash liquid-wetted packing media.
Regulatory-Compliant Exhaust Air Purification
Compliance with legal limits for VOCs, pollutants, and odour emissions in the production environment and surrounding areas. Minimization of the risk of complaints and fines from authorities, as well as avoidance of production restrictions.
Safe Continuous Operation
Low operating temperatures without flame and spark formation, low pressure, and controlled chemical reactions within a closed system.
User-Friendliness
Simple operation of the system using intuitive HMI controls and automatic dosing of the wash liquid. Option for integration into existing IT infrastructure.
Custom Design
Design of the absorption scrubber based on customer-specific production conditions, such as VOC or pollutant concentrations, volumetric flows, and industry-specific requirements.
Process Combination
Compatibility of the packed bed scrubber with additional technologies, particularly our patented COPLAS clean plasma technology for odour reduction.

Functionality & Application
Use of Absorption Scrubbers for VOC Removal & Odour Reduction
An absorption scrubber operates by directing pollutant-laden exhaust air through a bed of packing material wetted with wash liquid in a counterflow principle. Therefore, absorption scrubbers are also known as packed bed scrubbers. The packing material provides a large surface area for gas exchange between the exhaust air and the liquid. Wash liquid is distributed over the packing material from the top and flows downward as a thin film. VOCs in the raw gas are absorbed into the wash liquid, which collects at the bottom of the scrubber and is regularly drained. The cleaned gas flows through the packing material and exits from the top of the absorption scrubber.
Combination of Absorption Scrubbers with COPLAS clean Plasma Technology
Traditional alternative technologies for VOC abatement and odour reduction, such as biofilters or thermal combustion, have some significant drawbacks:
- High environmental impact
- Significant fire and explosion risks
- High ongoing costs
- Low efficiency
- High space requirements
At Riedel Filtertechnik, we therefore rely on the combination of various technologies for optimal treatment of your contaminated exhaust air. Our patented COPLAS clean plasma technology typically forms the core of our solutions and can be combined with packed bed scrubbers and activated carbon filters.
