preeflow® eco-DUO Precision Metering, Mixing and Dispensing System
About preeflow® eco-DUO Precision Metering, Mixing and Dispensing System
The preeflow eco-DUO high precision volumetric metering, mixing and dispensing unit measures, mixes and dispenses a wide range of materials for two-component dispensing with absolute control. The preeflow eco-DUO 330, preeflow eco-DUO 450 and eco-DUO 600 are two-component precision volumetric, positive displacement, dosing/mixing/dispensing systems that give you accuracy and repeatability using a progressive cavity pump principle.
The preeflow eco-DUO uses the precision dispensing technology of the preeflow eco-PEN; by integrating two eco-PENS through a manifold and a static mixing nozzle, the eco-DUO provides extremely precise metering, mixing and dispensing of critical two-part materials like epoxies and silicones.
“We are very satisfied with the performance of the eco-DUO450. The system has been reliably meeting
our requirements for many years with minimum maintenance.” – Petra Hofmann, Seba Dynatronic Mess- und Ortungstechnik GmbH
We can integrate the preeflow eco-DUO 330, preeflow eco-DUO 450 and eco-DUO 600 into any robotic dispensing system.
Features & Benefits
- Genuine volumetric meter, mix and dispense dosing
- Accuracy of ±1%, >99% of the time
- Viscosity independent
- Suck back effect
- Easy to clean
- Controllable dosing flow
Controller
The eco-CONTROL EC200 2.0 control system provides total control of preeflow volumetric valves during the dispensing process. It’s designed for either benchtop or rack-mounted location, dependent on the model.
Operating principle
The unit is operated via a bright, 7” touch screen, making it simple to use. External signals can be connected via I/O ports to a PLC for control in automated lines. Up to 100 dosing programs, with part management can be stored locally.
Error messages for filling level and motor current are also monitored (an RS232 interface is provided).
It is possible to control two eco-PEN precision volume dosing units (as a factory-fit option).
Features
- Quantity and start/stop program
- Set-volume readout in g or ml
- Dosing flow readout in ml/min and g/min
- Storage of up to 100 dosing programs with part management
- Set pressure and actual pressure readings in bar/psi

Other Information
Syringe adapter with integrated bleed valve
For use in applications where the chosen material is supplied in syringe barrels, an optional adapter with an integrated bleed valve allows for direct dispensing without the risk of air bubble formation.
Made of black anodized aluminium and stainless steel, and FFKM sealing elements, the syringe adapter is compatible with almost all materials and allows for air bubble-free dispensing, even after several syringe barrel changes.
With a 1/8-inch external thread, the adapter is well suited for the eco-PEN, eco-DUO series 300, 330 and 450 and eco-DUOMIX450.
