Painting And Drying Chamber

The painting chamber is a closed room where painting and drying manocurves are done, it is composed of:
Perimetric Walls, Frontal Walls, Lighting System, Ceiling and Basement.

Perimetrical Walls

The perimetrical walls are used to insulate the painting and drying chambers, both in terms of heat and noise preventing of course the dispersion of paint drops and solvent fumes in the surrounding environment.

1. Lateral walls are composed of 40mm thick modular type panels with groove and tongue joint systems, equipped with rubber seals. The Thermic insulation of the painting chamber is guaranteed by a polyurethane layer inside the panels.
   
2. Back walls are composed by the same panel as the above mentioned lateral walls.
   
3. Back covers and holds the upper parts of the rear panels and lungs.
   
4. Back corners are used for connecting lateral and back panels.
   

The spray booth frontal consist of:

1. Frontal wall which covers and holds lungs and the upper part of frontal side.
   
2. Service door for the entrance-exit of the operator equipped with a click opening mechanism.
   
3. Lateral pads are the panels upon which the doors are hinged.
   
4. Tabular frame is the bearing structure for the frontal walls.
   
5. Entrance door for the vehicle which will be painted.
   

Every door is supplied with windows which allows the operator to completely control the drying function. The windows are manufactured to resist high temperatures; they have a double sheet structure and a layer of plastic material to avoid splinters in case of damage.

Basement With Central Hole

The main function of the basement is to convey the air flowing out of the structure towards the extractor unit. It is composed by:

1. Support frame longitudinally made of beams and connected with two transversal heads. All components of the frame are made of galvanized and folded metal sheets.
   
2. The Grids are placed on the beams and are used as a treading base. Knurled metal sheets can also be used, however grids are recommended where air flows.
   
3. Frame Filter Basins are positioned between the grids and beams to hold basement filter.
   
4. Central hole conveys the air out of the chamber.
   
5. Boarding ramps allows the vehicle access to the chamber.
   

The basement can be constructed in masonry work for a different air flow position.

Lighting System

Internally the chambers is illuminated by eight lamp frames fixed to the upper part of the lateral panels having a 40 degree inclination angle as respects to the floor which guarantees better lighting.

The lamp frames are constructed in varnished light holders, each one with two 36 W neons. The neons are isolated from the painting area by the sheets of glass used for windows of the front doors.

Ceiling

The ceiling acts as a roof for the painting and drying chamber but also as a filter of support for incoming air it is composed of:

1. Light frames contain neons for the spray booth and is a support for the ceiling.
   
2. Trusses are fixed to the glass frame and are used to support the frames for filter holders.
   
3. Lungs are assembled on the upper part of the trusses and are used to regulate the flow of air.
   
4. Roof is made of galvanized metal plates and used to cover the spray booth.
   
5. Iron sheets are prepainted and used to cover the lateral upper side of the spray booth.
   

Generator Group

The generator group is used to create ventilation necessary for a perfect and homogeneous distribution of the paint, also to produce heat necessary for the drying phase. All generator group components are placed in a closed cabin connected to the painting spray booth by:

1. "V" tube for the connection between the generator group cabin and the painting/drying chamber.
2. Anti-vibration joint in plastic material which prevent the generator group mechanical vibrations from passing to spray booth.
3. Fire-cut damper, used to insulate painting drying chamber in case of overheating inside the generator booth.

The Generator Group Is Composed By:

1. Electrical Calibration Damper is used for partial recycling of the air to be injected inside the spray booth during the drying phase.
   
2. Fuel chamber in stainless steel with heat exchanger and an anti-explosion door.
   
3. Boiler is placed on the lateral outside wall of the spray booth and is equipped with mechanical fuel atomization.
   
4. Centrifuge fan is equipped with an electrical motor.
   
5. Washable pocket filters for filtering incoming air.
