Manual washing booths
Washing booths and tunnels are designed to work with water-based detergents, thus combining chemical, thermal and mechanical action, in order to guarantee excellent results and eliminate all traces of impurities or dirt.
Over the years Eurotherm has developed a series of washing systems capable of meeting the most varied needs to wash and degrease products of any shape and size.
Custom washing booths
Eurotherm is a leader in the production of reliable and flexible custom-made booths and washing systems.
Eurotherm booths and tunnels have long been recognized for their ability to create innovative solutions that are entirely custom-made to meet your specific needs.
Manual washing booth with skid
Manual washing booths are mainly used for washing operations of metal components or semi-finished products through a high-pressure water jet with phospho-degreasing solution and subsequent rinsing.
In manual washing cells, pieces of different shapes and sizes can be washed simultaneously.
Our manual washing booths are made up of:
- 01
Self-supporting structure in painted metal carpentry.
- 02
Roof in pre-coated with polyurethane foam panels.
- 03
Floor entirely made up of a pedestrian or driveway grating (depending on loading requirements).
- 04
Inclined pit with recovery pit placed under the grating to convey the sprayed liquid.
The fumes and vapors created during washing by the high-pressure water jet are captured by the suction wall which, through droplet separators, divides the water molecules contained in the air. Air is free to escape from the extraction funnel, while the liquid reaches the liquid recovery pit directly.
The liquid collected in the pit is thus sucked and reintroduced into the corresponding skid recovery tank (one dedicated to each phase, in order to limit contamination between the various tanks as much as possible), to make it immediately available, supplying the water jet in a continuous cycle.
The advantage of this system, defined as a closed cycle, (zero rejet), is that there is no liquid waste in the sewer.
Our washing booths can be integrated with the rest of the machinery in a painting system through the aerial transport system of the pieces.
Washing booth with or without foundation
Eurotherm washing booths are mainly realized with construction work, by placing an inclined pit under the grating.
It is also possible to carry out the recovery of liquids without foundations, thanks to the use of a structure containing a series of small hoppers above ground.
The skid liquid treatment for manual washing booths
The skid has the dual function of filtering and continuous reusing the liquids sprayed in a closed cycle, the basic version consists of 3 phases:
- Degreasing with cold phosphodegreasing solution;
- 1st rinse with mains water;
- 2nd rinse with mains water;
It is also possible to integrate further phases that include:
- a further rinsing with osmotized or demineralized water;
- a final passivation treatment.
A series of accessories are also available such as:
- hot degreasing tank (to use phospho-degreasing liquids at 50/60°C);
- oil remover (to remove the residues of working with oils and greases from the degreasing tank);
- sludge remover (to prevent the formation of polluting deposits inside the tanks caused by heavier processing).
The automatic replenishment of the liquid through a reverse cascade takes place by setting up, for each phase, a 1500 liter tank, each with its own pump dedicated to the recirculation of the liquid in the filter (to remove impurities and sediments) and to the feeding of the high pressure water jet with a dedicated hydraulic circuit.
The structure at the base of the skid also acts as a safety containment tank, ensuring control of any liquid spillage from the tanks and reducing environmental impact.
The exclusive strengths of the Eurotherm washing booths with liquid recovery are:
- 01
Easy management and maintenance of the system, as minimal manual checks and maintenance are required.
- 02
No liquid dispersion in the environment.
- 03
Waste reduction, as liquids can be used longer the contamination of the degreasing in the rest of the washes being limited.
- 04
High customization of the washing cycle.
The washing portal
Inside the manual washing booths it is possible to insert a washing portal suspended from the ground that runs along the entire length of the booth. Through ramps of nozzles, the tunnel washes the pieces with a washing cycle that is similar to that of tunnels and automatic washing cells.
The washing portal is particularly suitable for washing large batches of similarly sized pieces, such as frames, door and window profiles, sheet metal, etc.
The advantage of this solution is its versatility, since within the same booth and with the same skid, depending on the type of pieces, it is possible to wash larger pieces by hand and wash smaller pieces automatically.

In the technical data sheets the information about the dimensions of our systems are merely indicative because in Eurotherm we mainly realize customized booths and can adapt to any space constraint. Our technical team will counsel you best from design to testing.
Mainly in the industrial sector, metal carpentry, automotive, aeronautics, railway.
Our booths and skids are compatible with most of the phosphodegreasing solutions available on the market, even the most aggressive. Our technicians will be able to counsel you best, studying the solutions that are best suited to your needs.
The average duration of the washing cycle varies depending on several factors including the size, type of dirt, or material the pieces are made of, as well as the type of treatment performed. Generally speaking, the duration of the washing cycle of a 5-phase cell can vary from 10 to 20 minutes..
As far as in-line washing tunnels are concerned, the duration is established by the passage time of the conveyor inside the tunnel itself; in general, in automatic systems, it is calculated in terms of pieces per minute.
In manual washing booths the washing times are managed by the operator who, according to their experience and on the basis of visual controls, decides autonomously when it is time to pass from degreasing to rinsing and so on.
The booth and all the components are covered by warranty as per current regulations.
We design and build wash booths and tunnels that are designed to be integrated into coating lines to ensure a complete workflow whether it is a manual or continuous line, depending on your needs.
