A. Funktion vom Spray Coating System

The spray coating system (SCS) is a flexible solution for the non-contact and accurate application of oils and aqueous fluid. The spray jet is generated by means of a high-frequency pulsating valve and a one-fluid-fluid nozzle (not a two flow nozzle) Not always very fine droplet size is desired e.g. when a hot surface is to be coated. By varying the mouthpiece (nozzle) and the working pressure, a very large spectrum of droplet size can be achieved with a constant volume flow.


B. The benifit of Spray Coating System


  • Low plant pollution:

no suction required. Reduced contamination of the environment, as the spray mist almost disappears compared to a two-fluid nozzle. The fluid loss is almost negligible. (Efficiency = order quantity / spray quantity is close by 100 %)


  • Flexibility:

Up to 20 000 cycles per minute can be reacted with a PWM control. This achieves a very large control range (1:90) at constant pressure without changing the spray pattern. Flexible adjustments to the flow rate applied to the speed of the production line


  • Operation safety:

The PWM detects clogged nozzles during production.

  • precise application:

Smallest liquid flow control with constant jet angle. The spray pressure is always constant, because it works with a fixed operating pressure.


  • Profiling:

The nozzles can be controlled individually to achieve an automatic adjustment of a cross profile (cross profile control). The resolution of the cross profile starts at 30 mm and extends to 250 mm at a fixed nozzle distance to the coating surface


  • Turnkey system:

Easy to assemble and easy to integrate into existing production facilities.


  • Optionen:

Mixing and dosing unit for setting the chemical concentration are available.
