Tresu launches XL5i G3 coating circulator

Tresu has launched XL5i G3, a peristaltic coating circulator

Danish manufacturer Tresu has launched XL5i G3, a peristaltic coating circulator, which precisely regulates and stables the 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- and pressure control, the new XL5i G3 coating circulator 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 built-in 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 from Tresu prevents any contamination of air inside the chamber and eliminates micro foaming and undesired blistering of the print. 

Henrik Kristensen, vice president of Tresu Ancillary, commented: ‘Coatings responsible for high gloss, brilliant colors 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. 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 disturbance at high production speeds.’

Furthermore, the HMI with the new graphical user interface with intuitive universal icons, signals, and colors 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. Furthermore, the entire platform of the new circulator is entirely modular and ready to adapt to future needs and modes of operation by unlocking additional features on demand.
