For a company of primary importance in the world of quality painting, it was time to renovate their plant. The restyling was mainly dictated by two very strong needs:
- Have among their assets ovens that reach higher temperatures,
- To aim for energy savings.
The second point concerns one of the main work ethics that Eurotherm has been carrying out in recent years, not only for savings in economic terms, but also for environmental sustainability.
It is with these premises that we scrapped part of an old painting plant, aiming precisely at the quality and sustainability of the new plant components being capable of lasting over the years.
The automatic conveyor of the old line was maintained, while we have completely replaced the drying oven and the 200°C powder curing oven.
For both new ovens the company has chosen to switch from the combustion chamber to the direct air flow technology for greater energy savings and because the existing ovens built using an old concept were not able to reach the temperature required by the new treatment and painting process.
Reduction of processing times and energy savings
With a view to reducing processing times, we have added an IR gas pre-gelling oven before the curing oven: in this way, apart from the treatment of thinner sheets, it is sufficient to use only the IR oven for the polymerization, keeping the traditional switched off when not needed, with consequent further energy savings.
The result? We have increased the line speed from 1-1.2 m / min to 2 m / min: doubling the speed of the entire powder coating process while saving significantly on energy.
