As a print run progresses in rotogravure and flexographic printing processes, the ink temperature tends to rapidly rise above the ambient temperature. The higher temperature leads to:

  •   Increased solvent evaporation

  •   Unpleasant solvent odour

  •   Reduced print quality

  •   Higher top up solvent consumption

  •   Increased risk of fire

    The Valflow® ink temperature conditioner VIC11 is designed to maintain the temperature at the optimum level suitable for the processes and ambient conditions. This ensures consistency of printing and reduces the fugitive solvent losses.



On each print station, an ink circulating pump delivers ink from the tank to the print station. As the printing progresses, temperature of the ink varies over time. This variation in ink temperature results in higher solvent evaporation, which in turn means higher top-up solvent consumption. The ink flows through the inner spiral tube of heat exchanger to the print tray. The chilled water flows in the outer side of the tube and inside the shell, thereby cooling the ink. This ensures that ink temperature is maintained constant at set value.
