preeflow® eco-SPRAY High Precision Volumetric Dosing Unit, Spray Dispensing System
The preeflow eco-SPRAY spray dispensing system combines the reliable preeflow endless piston principle with a low-flow spray chamber, resulting in highly accurate spraying of low to high viscosity fluids with high edge definition. Based on preeflow’s proven rotor/stator dispensing technology, the eco-SPRAY provides superior process control.
This dispenser offers flexibility thanks to viscosity independence and a variable spraying pattern, as well as cost savings due to reduced waste and altogether higher process reliability than standard spraying technology.
The eco-SPRAY is capable of precisely nebulizing and spraying on either a continuous or intermittent basis. It offers a constant amount dispensed per area, uniform coating, and controllable round spray alongside technical features including defined quantity spraying, viscosity and primary pressure independent spraying and a controllable spray area.
We can integrate the preeflow eco-SPRAY into any robotic dispensing system.
- Viscosity independent spraying
- Spraying of defined quantity, regardless of primary pressure
- Controllable round spray area, with little overspray and high edge definition
- Constant amount/area and consistent spray-image results in uniform coating
- High chemical resistance allows a variety of media from low to high viscosity: grease, adhesives, ink, silicones, abrasive media, highly filled media, activators/primers
- Low maintenance system which is easy to clean
