The 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. The preeflow eco-DUO doses, mixes and dispenses a wide range of materials for two-component dispensing with absolute control.

preeflow eco-DUO 450 metering and mixing dispenser

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 450 and eco-DUO 600 into any robotic dispensing system.
