The preeflow eco-DUO is a purely volumetric dispensing system for precise mixing and applicating minimum quantities of two-component fluids.
With targeted controlling of the single components the mixing ratio can be adjusted up to the second place after the comma. Independent from viscosity fluctuations a clean and process reliable dosing can be realized. The controlled cutoff thanks to the suck-back effect marks the preeflow devices of the eco-DUO series next to many other features.
Self-sealing at approx. 2 bar with water as medium – the self-sealing effect increases with the viscosity
Dosing pressures up to 40 bar are possible
Due to the self-sealing no pressure valves are necessary
A basic suction pressure can be applied (for high-viscosity media)
The pressure tank is not required with self-levelling fluids
Dosing accuracy ± 1 %
Repeat accuracy > 99 %
eco-DUO600: guaranteed safety shut down
Smallest dosing quantity : 0,010ml
Adjustable dosing flow : 0,2 bis 12 ml/min
Weight : 1.100g
Description
The new eco-DUO450 precision-volume dosing unit made by ViscoTec covers many applications within the low to medium-viscosity dispensing range.
Theory of function
The preeflow® eco-DUO is a rotating, absolutely pressure-tight, positive displacement system with self-sealing rotor-stator arrangement. The controlled rotary motion of the rotor transfers the medium by displacement in the stator. The medium is unchanged by this process. And simply by switching to reverse-flow, preeflow® ensures a clean and controlled stop of materia or medium. No drips, no mess !
Smallest dosing quantity: 0,030ml
Adjustable dosing flow: 0,6 bis 32 ml/min
Weight: 1.600g

Description
The innovative eco-CONTROL EC200-DUO, made by ViscoTec offers a wide range of applications for 2-K-precision-volume-dispensers.
Theory of function
The control unit eco-CONTROL EC200-DUO has been developed and tested for accurate work with the preeflow 2-K-precisionvolume-dispensers. The control unit has a variety of configuration options to dosing, dispensing time and mixing ratio. All production-related values can be stored and changed at any time. The operation takes place over an intuitive user guidance using a graphical user interface. An integrated pressure control ensures the optimum process safety of the system. There is also the possibility of data exchange with a USB interface.
Description
The controller Speed-Control “plug’n’mix” from the brand preeflow was especially developed for 2-components applications.
Theory of function
Thanks to a standard terminal program can be programmed and configured the controller. In this case, the dispenser eco-DUO could be calibrated for different functions such as dosing speed or mixing ratio.
The volume speed, the dosing quantity and the suck back are be controlled the process by a 0 to 10 V signal. The integrated motor monitoring as overload protection for the dispenser can be processed as an error message.
The innovative precision volume dosimeter eco-SPRAY made by ViscoTec offers a wide range of applications for low to high-viscosity dispensing.
