preeflow-eco-spray spray dispenser


The preeflow eco-SPRAY precision spray equipment enables many applications in the low to high viscosity spray range.

Theory of function

The preeflow eco-SPRAY enables volumetric dosing based on the endless piston principle. The basis is a rotating, fully pressure-tight displacement system. It consists of a rotor and stator. The defined rotary movement of the rotor displaces the material volumetrically in the stator. This creates the flow. Controlled via the processor, a defined quantity is fed into the special low-flow spray chamber.

The precise nebulizing and spraying takes place continuously or intermittently. The combination of endless piston and low-flow spray chamber guarantees perfect spraying: From low to high viscosity materials with high edge definition and minimum overspray.
