Preeflow Eco-Duo
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.
Precision mechanics coupled with the latest digital control – a combination designed to save your capital. Use it and you’ll soon find out.
Eco-DUO600 with a new safety feature: Through the newly integrated pressure sensor in the 2K mixing head in combination with the flowscreen pressure evaluation a safety shut down of the system is guaranteed at any time.

eco-DUO 330Smallest dosing quantity: 0.005ml Adjustable dosing flow: 0.1 bis 6.6 ml/min Weight: approx. 1,100g DescriptionThe new eco-DUO330 precision-volume dosing unit made by ViscoTec doses smallest quantities which until now have not been achieved. Theory of functionThe 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! |

Eco-CONTROL EC200-DUO
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.
2K-Speed-Control plug’n’mix
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.
