Precise dampening solution dosing system with a pneumatic piston pump

Consistent, high dampening solution quality is essential for alcohol-reduced or alcohol-free printing. digidos.p is a precise dampening solution dosing system that is specifically designed to meet the requirements of IPA-reduced or IPA-free offset printing applications.

The control system continuously determines the necessary number of strokes of the pneumatic piston pump based on the incoming amount of fresh water and the specified target concentration. This pump has been specifically developed for the precise addition of dampening solution additives. It stands out due its chemical-resistant and elastomer-free design with minimum manufacturing tolerances. The integrated monitoring system ensures a particularly high level of operational reliability.

If desired, the digidos.p system can be upgraded, e.g. by adding a conductivity measuring system.
