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.
