Tresu has introduced the H5i G3, the latest version of its third-generation L-series coating circulator, designed to produce high performance circulation in special applications.
Intended for the automation of coating applications with high viscosity, high flow, high pressure, high speed, or high temperatures, Tresu believes the H5i G3 will help printers to save resources in special coating applications ‘while exploiting high speed coating with full control and no risk of micro-foaming and blisters.’
The circulator can control WB, UV or e-beam coating applications, meaning operators can save resources and ‘exploit the full creative potential of the coating media for creative eye-catching designs and strong branding.’
The H5i G3’s dual diaphragm pump circulator features auto adjusting and fully automated operations of coating pressure and connected tray level sensors, flow sensors, supply and waste level sensors as well as an optional anilox IR temperature measurement.
‘The H5i G3 makes an important contribution to production efficiency and automation of advanced coating applications and is the optimal solution if you have both high viscosity and high flow volume requirements,’ said Henrik Kristensen, Vice President of Tresu Ancillary. ‘The H5i G3 is easily retrofitted into existing coating applications as a stand-alone product or integrated inline into the latest designs of OEM coating solutions with full software integration.’
Tresu claims that, when used in combination with one of its own chamber doctor blade systems, the H5i G3 provides ‘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 reportedly prevents contamination of air inside the chamber and eliminates micro foaming and undesired blistering of the print.
The company also adds that its HMI with intuitive graphical user interface optimises operators’ start up times with fast and easy guidance and adds the ability to access a range of automated operation modes as well
Comprehensive data logging with statistical insights for Industry 4.0 operations is also possible using the Ethernet connection of the H5i G3. Finally, the entire platform of the new circulator is 100% modular and adaptable to future needs.
