Liquid painting booths
Liquid coating is a process that requires full compliance with three important objectives:
- the achievement of the desired quality
- the safety of the coating operator,
- the compliance with environmental regulations.
Eurotherm’s painting cabins are designed with these requirements in mind, preventing dust or other impurities from entering the system and optimizing the work cycle in order to save energy for the company.
4.0 liquid painting booths
Eurotherm technicians are at the forefront in the realization of 4.0 painting cabins, designed to be connected to production lines in full compliance with the parameters required by the regulations of the Transition Plan 4.0.
Suction walls for liquid coating
All cabins guarantee the passage of air at a speed of around 0.5 m/s, but they differ depending on the specific process that is employed to filter the air.
Standard suction walls with dry filtration
Depending on the size you need, you may purchase from us:
Minidry *
Our compact suction walls for color testing or painting small components. Download the product sheet here.
Tecnodry *
The most cost-effective range of suction walls. Download the product sheet here.
Eurodry-CA
Also available is the Eurodry CA range, which, in addition to primary and secondary filtration, is equipped with an additional filtering layer consisting of activated carbon cartridges. Download the product sheet here.
Suction walls with water film filtration
The water film suction wall is made entirely of stainless steel, and the paint filtration system consists of a waterfall as primary filtration, and a series of water cones as secondary filtration.
Eurotherm’s water curtain walls are completely customizable in shape and size and are designed to be incorporated into in-line painting systems or already existing painting booths.
With water curtain walls, your company won’t need to worry about replacing the filters periodically.
This way, you will eliminate the fixed cost of purchasing and replacing filters, and will only have to treat the recirculating water through a purifier or similar.
This is an optimal filtration system particularly for industrial productions with elevated production requirements.
Dry painting booth and water-based painting booth – which one should you choose?
Although both types of cabin are designed to meet the same coating requirements, they present different features. Both types can be easily integrated into coating systems with automatic step-by-step or continuous processing and fully automatic coating systems.
Dry painting booths are particularly suitable for large-scale components with lower production rates, while water curtain coating cabins are designed for coating large batches at higher production rates.
Custom liquid paint booths
Eurotherm creates custom liquid paint booths to solve any problem related to the processing of objects of all shapes and sizes.
The liquid paint booths are designed and built based on your specific needs, the parts to be treated, and the location where they will be installed.

The goal of Eurotherm’s liquid coating booths is simple: the less contamination in the working environment, the higher the quality of the final coating. In order to achieve this, we use a number of measures, depending on your needs.
Horizontal flow liquid coating booths
HORIZONTAL FLOW
This is our basic solution for carrying out liquid coating in safe conditions.
Air is sucked in directly from the front opening of the booth through the suction wall located in the bottom.
Liquid coating booths with oblique flow
Pressurized liquid painting booths with vertical flow
VERTICAL FLOW
Pressurized coating cabins are the most professional, being equipped with:
- vertical flow
- filtering plenum with total coverage of the roof
- filtering floor
This way, the air flow is more homogeneous than in the above-mentioned types of painting booths, and the working environment conditions are constant over time. These are features that guarantee an optimal environment for the application of the paint as well as the safety of the operators.
In this case it is necessary to use one or more AHUs in supply and extraction to maintain a constant aeraulic balance of the system and to ensure the temperature and humidity of the air in the booth to be constant over time.
For best results, Eurotherm engineers recommend an excavation to be made under the grate, although it is possible – through a raised structure – to construct the cabin without any building work.
For specific applications, it is also possible to provide floor filtration with water cones instead of dry filtration.

FAQs about Eurotherm liquid coating cabins
We mainly manufacture bespoke cabins, designed to meet any production or space requirements. Our technical team will provide you with the best advice, from design to testing.
The entrance of the pieces into Eurotherm painting booths can take place, depending on the needs, either by overhead crane or overhead conveyor. It is however also possible to use trolleys or forklifts.
The main fields are industrial (light and heavy carpentry), aeronautical, railway, naval, piping – oil and gas – automotive, furniture, restoration.
The coating must be chosen depending on the surface to be coated as well as on the end result you wish to achieve. Our technical department will support you in your choice, following the technical phases of the coating process step by step.
The booth and all the components are covered by warranty as per current regulations.
The booths do not require any construction work to be carried out, except in the case of vertical flow booths. In the latter case, air filtration and recycling will take place within the foundations, while in other cases raised bases will be designed.
Painting booths without foundations can be easily disassembled and reassembled in another location and can be a good solution for companies that, for example, need to work in rented warehouses or need to carry out particular temporary works.
Our technical team can advise you on the best solution for your needs.
We design and build painting booths that can be assembled in line with washing, drying and low temperature drying ovens to ensure a complete workflow, depending on your needs.
