Preeflow Eco-Spray

The dosing principle of preeflow® dispenser is an endless piston dispenser. This special dosing geometry allows an endless and pulsation free dosing flow. The possibility of reversing the dosing flow (suckback) will prevent from dripping and leads to a perfect control of media stringing or dripping. Especially sensitive fluids with high viscosity and fillers inside experience a gentle treatment due to the low shear stress and the low pressure. Therefore, it is: many tasks – one principle !
Conformal coating Preeflow® one for all : Sealing – Bonding – Micro dot – Dam & fill – Underfill – Glob top

Benefits
The medium is unaltered by this process. And simply by switching to reverse-flow, preeflow® ensures a clean and controlled stop of material or medium. No drips, no mess – always!
Preeflow® products offer the ideal properties to ensure that all relevant 1 & 2 component applications in several industries are perfectly dosed !

The precision volume spray dispenser eco-SPRAY, made by ViscoTec, is suitable for various applications in different spraying areas.
The revolutionary combination of the reliable endless piston principle and a low-flow spray chamber guarantees perfect spraying of low to high viscosity fluids – with high edge definition !
 

Description

The innovative precision volume dosimeter eco-SPRAY made by ViscoTec offers a wide range of applications for low to high-viscosity dispensing.

Theory of function

The new precision volume dispenser eco-SPRAY made by ViscoTec offers a wide range of applications for low to high viscosity spray media. The preeflow® eco-SPRAY guarantees a volumetric spray application based on the endless piston principle. The base of this new microspraying technology is still our proven rotor/stator technology. Due to a defined rotary motion of the rotor the medium in the stator is volumetrically replaced and conveyance is created. Thus a determined amount of medium is process controlled and directed to the special low flow spray chamber.

The precise nebulization and spraying can take place continuously or punctually. The revolutionary combination of the endless piston principle and the low flow spraying chamber guarantees perfect spraying of low to highly viscous media with high edge definition and lowest possible overspray.
