Water Scrubbers and Smoke, Soot & Grease Collectors for Grills, Ovens and Biomass Systems
ETC Group water scrubbers and smoke collectors are designed to treat soot, grease, odours, aerosols and particulate generated by charcoal and wood-fired grills, professional barbecues, wood-fired ovens, biomass boilers, heat generators and commercial kitchens. The technology is based on a multi-stage hydrodynamic water reactor developed through more than 20 years of engineering research and industrial applications. The controlled gas flow promotes progressive particulate capture while maintaining low pressure loss, continuous operation and reduced maintenance without disposable mechanical filters. Performance has been independently validated by ACCREDIA-accredited laboratories, achieving particulate reduction exceeding 95.2% under certified test conditions.

Water Scrubbers and Smoke Collectors for Biomass Boilers and Heat Generators
For restaurants, steakhouses, barbecue venues and commercial kitchens
ETC Group water scrubbers and smoke collectors are designed to treat smoke generated by charcoal and wood-fired grills, where combustion produces soot, grease aerosols, odours and fine particulate matter. The advanced multi-stage hydrodynamic water technology promotes progressive particulate capture through controlled fluid dynamics and water scrubbing, reducing emissions while protecting exhaust ductwork and improving long-term system reliability.
For civil, commercial and industrial heating systems
ETC Group water scrubbers are engineered to treat smoke produced by biomass boilers fired with wood, pellets, wood chips and other solid fuels. The advanced hydrodynamic water technology reduces combustion particulate, limits deposits inside flue systems and helps extend chimney service life while ensuring reliable, continuous operation with low maintenance requirements.
For pizzerias, bakeries and high-capacity cooking systems
Designed for the continuous treatment of smoke from wood-fired and biomass ovens, ETC Group systems reduce soot, fine ash and combustion particulate before discharge into the atmosphere. The multi-stage hydrodynamic water reactor maintains high performance during continuous operation, helping to keep flue systems cleaner, reduce maintenance requirements and improve overall emission control.

Frequently Asked Questions (FAQ) on Soot Scrubbers
How does a water scrubber work for smoke treatment?
A water scrubber treats combustion smoke by passing the airflow through a sequence of water washing stages, controlled fluid dynamic changes and permanently wetted surfaces. ETC Group systems use a multi-stage hydrodynamic reactor designed to progressively increase the interaction between smoke and water, promoting the capture of soot, particulate matter and grease aerosols. The system is engineered to maintain low pressure loss, continuous operation and does not require disposable mechanical filters.
Can a water scrubber also reduce odours?
Water treatment helps reduce part of the compounds responsible for odours, although its effectiveness depends on the composition of the smoke and the combustion process. Where higher odour reduction is required, the system can be integrated with post-treatment technologies such as ozone generators, electrostatic filters or activated carbon filters, selected according to the specific application.
Which applications can use an ETC Group water scrubber?
ETC Group water scrubbers are designed for treating smoke generated by charcoal and wood-fired grills, professional barbecues, steakhouses, wood-fired ovens, bakeries, biomass boilers, heat generators, coffee roasters and many industrial applications. Each system is sized according to airflow rate, smoke temperature and the specific characteristics of the process.
Why is smoke from charcoal grills more difficult to treat?
Smoke generated by charcoal grilling contains soot, fine particulate matter, grease aerosols, organic vapours and odorous compounds at the same time. This combination makes the treatment process more demanding than many other combustion applications. ETC's multi-stage hydrodynamic technology is specifically designed to progressively increase the interaction between smoke and water, improving the capture of particulate matter and grease aerosols throughout the treatment process.
What is the difference between a water scrubber and a traditional scrubber?
Both technologies use water as the treatment medium, but the main difference lies in the reactor design. ETC systems guide the smoke through a carefully engineered flow path featuring controlled directional changes, multiple washing stages and fluid dynamic variations that progressively increase the interaction between particulate matter and water. The objective is to achieve high treatment efficiency while maintaining low pressure loss and reduced maintenance.
Do ETC Group water scrubbers require replacement mechanical filters?
No. The primary treatment process takes place through the interaction between smoke and water inside the hydrodynamic reactor. There are no disposable mechanical filters that require periodic replacement. Routine maintenance mainly consists of cleaning the unit, checking the spray nozzles and managing the water according to the instructions provided in the operation and maintenance manual.
Can a water scrubber be installed on an existing chimney system?
In most cases, yes. ETC water scrubbers can be installed on existing flue systems after evaluating the chimney configuration, airflow rate, smoke temperature, available fan pressure and installation space. Each installation should be assessed individually to identify the most suitable technical solution.
How do I choose the most suitable water scrubber?
Selecting the correct model depends on several technical factors, including the type of fuel, airflow rate, smoke temperature, chimney configuration, operating hours and the treatment objectives. Proper sizing ensures the best balance between treatment efficiency, system reliability, ease of maintenance and energy consumption.
Why is pressure loss important in smoke treatment systems?
Every exhaust system operates with a limited amount of available fan pressure. A scrubber with excessive pressure loss may reduce airflow and compromise the overall performance of the installation. For this reason, ETC reactors are engineered to provide high treatment efficiency while keeping aerodynamic resistance as low as possible.
Why does ETC Group use multi-stage hydrodynamic technology?
Treatment efficiency depends not only on the amount of water used but also on how the smoke flows through the reactor. ETC's multi-stage hydrodynamic technology guides the smoke through a sequence of washing stages, flow section variations and permanently wetted surfaces, progressively increasing the probability of particulate capture. This engineering concept, developed through more than twenty years of experience, allows the construction of compact, reliable systems designed for continuous operation.
