Leading global OEM Tresu (Kolding, Denmark) has released its new Tresu XL5i G3 Peristaltic Coating Circulator that ensures precisely regulated and stable flow for uncontaminated coating with sensitive or special aqueous or UV coatings for all printing applications. Introducing “a new range of opportunities in automation, connectivity as well as level control and pressure control,” the XL5i G3 enables full and automated control of a range of high-quality coating applications with sensitive and special coatings – such as opaque white, gold and silver metalure, pearl luster, blister, high-gloss, scented or silky soft touch effects. Used in combination with a chamber doctor blade system and customized open cell anilox roll, the Tresu XL5i G3 features separate supply and return pumps that provide full control of the enclosed circulation from the bucket to the chamber, where the coating fills the cells of the anilox roller. This Control Pressure Technology system prevents any contamination of air inside the chamber and eliminates micro-foaming and undesired blistering of the print.
“Coatings responsible for high-gloss, brilliant colours and appealing tactile effects are powerful ways to add brand value – especially for luxury and personal-care packaging, where a differentiating point-of-sale impact is crucial,” said Henrik Kristensen, Vice-President of Tresu Ancillary. “However, the functionality of these coating types depends on relatively large layers, which are delicate to handle. Tresu’s new XL5i G3 Coating Circulator ensures that these coating media are carefully transferred at precise viscosity, flow and pressure levels – securing that desired print and coating results are achieved and repeated with full automation and no disturbances at high production speeds.”
The unit’s HMI with a new graphical user interface with intuitive universal icons, signals and colours, optimizes operators’ time with fast and easy guidance to basic start-up and operation commands, and the ability to go one step deeper and access a range of automated operation modes. Comprehensive data logging with statistical insights for Industry 4.0 operations “is now a real opportunity” using the Ethernet connection of the Tresu XL5i G3. The entire platform of the new circulator is 100% modular and can adapt to future business and production needs and modes of operation by unlocking additional features on demand. The XL5i G3 is also an ideal solution for special and sensitive UV or aqueous-based coatings, and can be operated as a standalone product or integrated inline into an existing printer or print workflow, with full software integration.
