Safety & Ease of Use

With an integral bund and separate doors to the dosing & fill/control compartments, the unit provides a safe & robust fully enclosed lockable unit. By using Digital dosing pumps which have a user interface that allows the dosing rate you want to be entered directly on the screen, the systems are very simple to use. Furthermore, with a very wide turn-down ratio (100:1 for smaller pumps 1000:1 for large pumps) and no need for complicated stroke rate calculations, the system is truly “plug & play”.
