WEKO | Flow and SIGMA Liquid Application System

NON-CONTACT LIQUID APPLICATION SYSTEM

Non-contact liquid application system

WEKO Flow and Sigma Liquid

The WEKO | Flow and WEKO | Sigma is a non-contact liquid application system with a unique spray window. For instance, a wide variety of liquids (water and oil based) can be applied with the highest precision and reproducibility to enhance surface functionality on different materials. The rotors are individually supplied with the desired amount of liquid via specially designed throttles and the frequency-controlled pump.

The WEKO | Flow and WEKO | Sigma non-contact liquid application technology in brief

The WEKO | Flow liquid supply unit transfers the chosen liquid to the WEKO | Sigma rotor carrier. The flow unit controls the desired amount of liquid. The rapid spinning rotor discs create a pre-defined jet stream of micro droplets sprayed onto the surface. These droplets form therefore a consistent and evenly film onto the surface. What’s more, the application volume adjusts to the speed of the web. Additionally, non-sprayed liquid will return to the storage tank of the machine.

CONDITIONING THROUGH RE-MOISTENING

WEKO DIGICON - Conditioning through remoistening

WEKO | Digicon

In digital printing, dryer systems are used to dry water-based inkjet inks or to fix toner-based systems. Paper consists of organic fibers whose properties change negatively when exposed to heat.

Conditioning of paper through re-moistening in the High Speed Digital inkjet Printing Industry by WEKO | Digicon or WEKO | Webcon reverses undesirable effects like paper curl, waviness, electrostatic charges and register differences.

Effective and Efficient

Besides supporting excellent printing results, the WEKO technology is also efficient in the exact required sprayed water quantities. Therefore, you are saving valuable resources.

Global Player partnering with market leaders of printing presses

Hence, WEKO is a global partner with market leading printing press manufacturers. This is because the WEKO technology sets the industry standard in inline remoistening. Another key point is that with local service and spare part points, we provide the best possible support in servicing and maintaining your spray units.

The WEKO Digicon technology in brief

The WEKO liquid supply unit provides the exact amount of liquid. The integrated pump transports the liquid from a storage tank to the rotor carrier. The rotor disc spindles and forms pre-defined jet stream of micro droplets. These micro droplets spray evenly over the web, and create therefore a uniform liquid film. Unused liquid returns to the liquid storage tanks.

Your Benefits

  • Precise, minimal and repeatable application quantities
  • Contact-free, clean application (no wrinkling)
  • Wide range of applications for all paper grades and ink coatings
  • Automatic adaptation to printing speed
  • No wear and tear or job-related replacement parts (rollers, sleeves, nozzles)
  • High flexibility – single or double-sided application with variable quantities possible
  • Highest availability due to automatic cleaning program
  • Intuitive, easy operation
  • Simple installation without complicated alignment
