Benefits
Working station
Process consisting of transferring, screening and deaerating the colour to deliver it to the coating heads (film press, on-line or off-line coaters).
Benefits
- Optimal coating colour quality (excellent deaeration, dry contents and viscosity regulation and fine temperature control)
- High filtration efficiency of fresh coat and header coat
- Smooth run of the coating process (pulse-free supply)
- Maximised recovery and recycling of coating colour
- High-availability delivery system adapted to modern coating methods and increasing machine speed
