Lidergraf, a Portuguese graphic arts company, has chosen to use Atlas Copco compressed air, blower and vacuum solutions to meet its demand for 100% oil-free, high-quality air to ensure the quality of its products.
Since its formation in 1994, Lidergraf, headquartered in Vila do Conde, Portugal, has steadily grown to be one of the largest graphic arts companies in Portugal with 145 employees and annual revenue of around €20mn.
Now, with the construction of a new building and the acquisition of a second rotary machine, Lidergraf is able to operate 24 hours a day, seven days a week. However, the company also has had to increase the compressed air, vacuum and blower capacity to meet production demands.
The company installed two ZT 132 VSD FF and ZT 110 FF oil-free compressors with integrated adsorption dryers, a ZS 55+ VSD oil-free screw blower, and a ZE oil-free screw vacuum pump. Featuring energy-efficient integrated dryers, both compressors provide 100 percent pure, clean oil-free air that complies with ISO 8573-1 Class 0 (2010) certification. This means zero risk of contamination; zero risk of damaged products; and zero risk of losses from operational downtime.
Its ZT 132 VSD FF compressor and the ZS 55+ VSD oil-free screw blower both feature variable speed drive (VSD) technology. VSD technology adjusts the motor speed to the air demand automatically, achieving substantial energy savings of 35 % on average. In addition, VSD reduces the energy requirements in the overall production process.
Antonio Crespo, company maintenance manager, said Atlas Copco offers “reliable, high-quality and energy-efficient equipment, especially in the speed variation compressor with integrated dryers.”
“As the constant production of high-quality compressed air is very important for our production, the partnership with Atlas Copco proves to be excellent,” Mr Crespo said.
Atlas Copco is based in Stockholm, Sweden, and in 2012, had 39 800 employees and revenues of BSEK 90.5 (BEUR 10.5).
