The application and drying of paint are two decisive steps in the paint booth of your car bodywork.
How can you reduce the energy consumption of this booth while ensuring optimal quality for your customers? Controlling the temperatures during the application and drying phases by using high-precision electronic control is one solution.
The activity of a car bodywork shop consists of repairing and then painting the bodywork of damaged vehicles.
The paint booth is a ventilated, illuminated and heated enclosure for spraying layers of liquid paint and varnish. Its use meets safety standards.
Heating and temperature control are major components of the booth that ensure that the paint hardens and dries quickly.
The paint is applied by spraying in spray booths (spraying). This stage is carried out at a temperature generally between 20°C and 25°C with a controlled air speed in the booth.
For drying, various techniques are used, including the most common one, hot air, which consists of raising the temperature of the booth to 60°C once the application is complete in order to obtain satisfactory results.
These two operations are essential for the paint to harden.
If these conditions are not met, the paint may flake more easily.
Cooling is the phase that ends the painting session. Temperature control is very important for the quality of the work.
The paint booth is the most energy-intensive part of a car bodywork, accounting for about 75% of total energy consumption. The aim is to use the booth as sparingly as possible in terms of heating and duration of use.
The dimensions of a hot-air paint booth, and its energy consumption for heating, are calculated according to :
The use of water-based paints in a hot-air paint booth leads to an oversizing of thermal power and energy consumption.
Fuji Electric's high-precision temperature control ensures temperature control during the application and drying phases for perfect paint results.
A two-degree-of-freedom PID control algorithm prevents temperature overshoot. A high-performance microprocessor ensures ultra-fast control to limit temperature variations regardless of the outside temperature and environmental conditions. The temperature is stable and controlled.
The PID PXF temperature controller reduces energy consumption for the paint booth air heating.
The 2 temperature set points allow easy change between application and drying temperature. Its large, high visibility display provides improved viewing of the set temperature in all light conditions.
Productivity is increased by improving the use of the booth.
The ergonomic and ultra-compact design allows the controller to be easily integrated into new booths or existing systems with minimal cost, space, and wiring.
Alarms in the event of over-measurement ensure protection of the booth and the painter.
Booth commissioning costs are reduced with the built-in auto-tuning feature that ensures the best accuracy is achieved under specific conditions.
Fuji Electric PXF controllers offer unrivalled uptime and reduce your maintenance and operating costs.
They can also be combined with air humidity controllers to match the humidity of the outside air with the required temperature inside the booth.
