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 can integrate the preeflow eco-DUO 330, preeflow eco-DUO 450 and eco-DUO 600 into any robotic dispensing system.

The eco-CONTROL EC200-DUO offers a wide range of applications for the eco-DUO450 and eco-DUO600.
The eco-CONTROL EC200-DUO control unit has been developed and tested for accurate work with the eco-DUO 2K precision volume dispenser. The control unit has a variety of configuration options such as 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 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.

|Model||Accuracy of dosing||Repeat accuracy||Mixture ratio||Min. dosing quantity||Volume flow|
|eco-DUO 330||± 1%||> 99%||1:1 to 10:1||0.005 millilitres||0.1 to 6.6 millilitres per minute|
|eco-DUO 450||± 1%||> 99%||1:1 to 10:1||0.01 millilitres||0.2 to 12 millilitres per minute|
|eco-DUO 600||± 1%||> 99%||1:1 to 10:1||0.03 millilitres||0.6 to 32 millilitres per minute|
For applications where the material is supplied in syringe barrels, an optional cartridge adapter with an integrated ventilation system allows for direct dispensing from the syringe. With a 1/8 inch external thread, the adapter is ideally suited for the eco-PEN and eco-DUO series 300, 330 and 450. With the help of a reducer the adapter can also be used with the 600 and 700 series.
Made of black anodized aluminium and stainless steel, and FFKM sealing elements, the cartridge adapter is compatible with almost all materials. By means of a standardized Luer-lock connection (1), the material cartridge can be quickly attached to the adapter. The adapter itself can be turned by 360° without resistance until the final lock with the help of the hexagon screw (2), and thus allows the user a maximum degree of mobility and flexibility. With the aid of a small piece of hose (Øi 4mm) which is plugged onto the hose nipple (3) and by opening the bleed screw (4), the air can escape from the pump housing and any excess material can be quickly and cleanly disposed of together with the hose piece. In this way, air bubble-free dispensing can continue even after several cartridge changes.
