Presentation

Multi-zone temperature control units enable stable production conditions, even when using paint with different viscosity.

This is indispensable for high level waterless and conventional printing – especially under difficult conditions, such as IPA-reduced or IPA-free printing and when using spot colors. E. g. at banknote and security printing.

THE PROCESS:
The temperature in the ink temperature control circuits is controlled on the basis of the return flow temperature of the associated ink units or, particularly in waterless offset printing, using an IR temperature sensor in the ink unit of the printing press for a direct control of the ink roller surface temperature.

In other applications, or if other requirements have to be met, the system can also be used to control the feed flow temperature. If required, the press speed can be used as an additional control variable, allowing an even more precise temperature management. The entire system is designed as an atmospherically closed system incorporating a pressure expansion vessel and a pressure relief valve, offering maximum protection against corrosion and algae growth.

Small leaks, e. g. in the area of the cylinder rotary unions, are compensated for by an automatic water refilling device.

Technical features

each ink unit is temperised by a separate circuit perfect ink viscosity due to individually temperised ink units separately temperised ink ducts ensure stable pre-defined conditions heating function for quick machine availability and reduced spoilage atmospherically sealed system prevents production related damage through corrosion and algae growth individually connectable to central control unit of the printing press or external data remote control
