Description
The preeflow eco-SPRAY precision volume dispenser combines the reliable 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.

Applications

  • Dosing
  • Greasing
  • Coating
  • Marking
  • Micro-nebulisation

Features & Benefits

  • 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
