The eco-DUO330 precision volume dispensing unit made by preeflow dispenses the smallest of quantities of 2-component materials which until now have not been achieved.
Theory of function
The preeflow eco-DUO330 is a rotating, perfectly pressure-tight, two component dispensing system with self-sealing rotor-stator arrangement. Conveyance action by material displacement in the stator through controlled rotor movement. Safe conveyance without any modification to the material. With its suck back option, the mixing dispenser ensures a clean and controlled material cut-off while preventing post-dripping effects.
Other variants of the standard products are available on request, e.g. stator VisLas / drive train with rotor Diamond Coated / seals PTFE.Data sheet eco-DUO330 Spare parts eco-DUO330
The control unit eco-CONTROL EC200-DUO from preeflow offers a wide range of applications for high-precision two component dispensing systems.
Theory of function
The control unit eco-CONTROL EC200-DUO has been developed and tested for accurate work with the preeflow high-precision, volumetric, 2-component dispensers. The control unit has a variety of configuration options to dispensing quantity, mixing ratio and dispensing time.
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.Data sheet eco-CONTROL EC200-DUO
