SLIDE9-2Amir is the name of the paint application booth with aluminium sections and glazed walls which, after extensive studies, has led to the creation of a booth with a modern and ergonomic design.

In the Amir booth the paint application area is contained within aluminium walls that are either partly or fully glazed. The sections and nodes between the structures have been specifically designed to reduce the possibility of dirt and dust being deposited on them and to assist with cleaning and maintenance. The design also includes the possibility of incorporating, into the side walls, boxes containing the spray guns and the devices for housing robots.

The Amir booth represents the best aesthetic and functional design for painting booths in the automotive sector.

SLIDE1Hydrospin plus is the wet floor booth for washing air extracted from the more modern and efficient painting booths operating on the market today. It is the result of a long string of successes in this field which began with the first system developed by Drysis, which was followed by different variations and subsequent modifications made over the course of the last 50 years, firstly by Haden and then by Geico. Today it represents the ultimate wet scrubber in terms of both its technical performances and its ease of maintenance.

The Hydrospin plus system exploits the co-current washing principle of extraction with water, in order to remove the paint overspray particles generated in the painting booth during the application process.

slide21Dryspin is the innovative booth floor that is based on the dry separation of paint overspray; as the actual name of the product suggests, it uses calcium carbonate instead of water for separation and is therefore completely dry.

The Dryspin system results in a drastic reduction in air conditioning costs. The expelled air can be reused in the automatic sections without any significant treatment (which is not the case in wet floor booths, which require the expelled air to be dehumidified and then reheated.

Given that it is a dry system, there is no need to treat booth waters, something that is essential in wet floor booths in order to guarantee the quality of the recirculated water. The system is simple and compact and does not require a water recirculation pit.

SLIDE10Modular, compact and simple: there are a number of different features that make the Powderspin the perfect painting booth for the application of powder-based paints for the automotive sector.

During the painting phase the paint particles that do not adhere to the body are carried by the downward flow of air into the dry filtering units that capture the paint, allowing the air to pass through so that it can be recycled or expelled. The connection between the floor of the booth and the filtering units is created by means of cones that have been designed in such a way that no powder deposits are left on the walls, nor is there any uniform blocking of the filters, which results in a longer working life for the filtering unit. The powder trapped by the filters can be recovered and reused.

The Powderspin system has a significantly lower environmental impact than systems using liquid paints. With no need for the typical treatments of a wet or dry floor booth using liquid paints, energy consumption is drastically reduced.

SLIDE-copia1One of main goals that Geico has set itself is that of assisting, significantly and gradually, with the reduction of energy consumption. This is made possible by constantly improving the optimal management of air flows, as is demonstrated by the different solutions identified by Geico.

Air Cascades: to increase the savings in the conditioning of ambient air, Geico recommends reusing the air extracted from the manual application booths in the robotic application booths.

Air Recirculation: this consists of reusing the extracted air in the same booth, guaranteeing the minimum renewal necessary in order to limit the concentration of solvents and minimise the consumptions of ambient air conditioning.

6 zones: this consists of air treatment units with advanced logic operation geared towards the minimum consumption of energy in compliance with the thermo-hygrometric conditions required for applying the paint.

CTA (Air Treatment Unit) Operating Software this software oversees the operation of the CTA (air treatment unit), adjusting the flows and temperatures on the basis of the work being undertaken inside the booth (painting phase, cleaning phase, maintenance, shift change, plant stop).

Post-recovery heat system: consists of the recovery, by means of enthalpy or thermal wheels, of the energy contained in the flow of air expelled from the booth, for the purpose of heating the infeed of air in winter and cooling it in summer.

SLIDE21-2The treatment of waste water consists of systems for the separating and drying of paint sludges by the painting booths’ recirculated water.

The paint overspray is collected by the water that flows on the bottom of the painting booth and is carried towards a decanting pit, inside of which doses of chemical products are added that encourage the paint to float to the surface and accumulate.

The sludges produced are subsequently separated mechanically from the water that can then be reused as a means of separation on the floor of the Hydrospinplus booth. The treatment pits can be separated according to paint product or, depending on the products applied, they can collect the water originating from several painting booths.

The paint sludges produced can be subsequently dried to reduce the concentration of water and the related volume and weight.

SLIDE19RTO is an incinerator system devised for the reduction of VOC emissions originating from the evaporation of paints inside the booth. It is particularly suitable for treating high volumes and low concentrations and is created using centralised solutions, normally integrated with the post-recovery of heat for the reduction of traditional energy carriers. The use of ceramic infills with a greater specific exchange surface makes it possible to achieve thermal efficiencies of up to 98% with the subsequent reduction in consumptions.

dryspin_2185-MOVIMENTOThe advantage of the sliding door is first and foremost that of drastically reducing the costs and times required for cleaning the booth’s gratings, because their disappearance during the paint application phase means there is no risk of them becoming dirty as a result of the paint. The upshot is a simple system that does not require any special maintenance.

The gratings on the floor of the application booth consist of two horizontal pedestrian “shutters” located on the sides of the booth. During the application phase the gratings wrap themselves around the counter pulleys located on the outside of the booth, causing the normal walkway to disappear. However, during cleaning or maintenance the gratings return to their original position, allowing operators to access the booth.

slide1371The ELENE (ELastic ENergy Ecology) application booth is a painting booth, either manual and/or automatic, that is capable of adapting its own operating length to that of the production required.

 

The creation of a paint plant is often influenced by the demands of the market; therefore it can occur that plants are commissioned for the design project’s production capacity but actually produce fewer bodies.

The ELENE allows the booth’s ventilation and its operation to be adjusted to the length actually required for the production that is in progress.

When passing from one production level to a lesser one, some of the booth’s sections are not ventilated and the spraying operations (manual or automatic) are divided up differently over the zones that are already in operation.

The length of the operating booth is adjusted to the actual production that is in progress resulting in considerable energy savings.

SLIDE22The Flash off is the area in which the evaporation of the aqueous content of the water based paints occurs, before the application of the transparent glaze.

In addition to the classic execution of the hot air flash-off, Geico has also developed the hot air flash off with thermal wheels or with air that is dehydrated through direct evaporation.

slide138This is a modular system, patented by Geico, for handling bodies on skids; it is particularly suitable for reducing powder and dirt deposits and facilitate their removal.

The Newty system can replace table conveyors or sections of continuous chain conveyors.

  • It consists of a closed tubular structure within which are located the gear mechanisms and the belts or chains that provide the movement for the rollers on which the body-carrying skid can move. The tubular form, with no flat surfaces, and the conveyor system’s overall reduced surface area reduces the deposits of powder or dirt, making it easier to clean.
  •  Servicing of internal parts is assured by means of removable hatches.

slide19-2Thanks to its advanced flexibility, the table conveyor allows bodies to be handled inside the spray painting booths, alternating continuous and intermittent movements, even where space is limited.

It is an offshoot of the modular skid conveyor systems, (sequence of tables) used for connecting the different areas of a paint shop. The system boasts simple mechanical installation.

slide8This is a simple, widely tested conveyor system that allows bodies to be handled inside spraying booths with a continuous movement.

This conveyor is essentially a double chain onto which the bodies on skids are placed at a normal or variable pitch, and it advances at a fixed speed that determines the cycle time.

The automated spraying systems perform the cycles “following” the bodies that never stop moving. The type of process and therefore the set up in which it is located requires special protections and measures (the chain’s sections have been designed in such as way as to avoid, as much as possible, their becoming dirty).

SLIDE20-2This is the conveyor on the ground, with rollers directly incorporated with the parts of the plant. The result is a modular, compact system with smaller surface areas exposed and therefore fewer surfaces prone to becoming dirty. This ensures that the system is easy to clean and maintain. In addition to being a simple, well-established system, the integrated conveyor boasts quick installation and ease of commissioning.

Generally speaking the conveyor is a separate component which is inserted into a painting plant and operated separately by the plant itself. In line with the characteristics called for by the place of work (painting booth, sealing, working-deck, control areas or manual working, storage etc), Geico has come up with a specific solution for plants which allows the components of a conveyor system to be directly incorporated into the structures themselves or on the floor part of the plant.
