Description
One Seven OSP-16i Proportioner
The One Seven OSP-16i is a compact, electrically driven foam proportioning system designed to deliver precise and reliable mixing of foam concentrate and water in firefighting operations. Built with innovative sensor technology, the OSP-16i continuously monitors flow rates and automatically adjusts dosing to maintain the correct proportioning rate. This ensures consistent performance, even when foam concentrate viscosity changes due to temperature fluctuations.
A bright colour display provides intuitive operation and clear monitoring of system data. For maximum reliability, the OSP-16i is equipped with emergency programs that can be activated at the push of a button, ensuring uninterrupted firefighting capability in demanding conditions.
With a flow rate range of 0.2 to 16 litres per minute and an integrated plunger pump compatible with all firefighting foams up to 500 mPa*s viscosity, the OSP-16i offers flexibility across a wide variety of applications.
Optional extras such as tank filling pumps, tank level indicators, and multi-tank changeover valves are available to expand functionality. This allows operators to quickly switch between different foam classes during an operation without manual adjustment.
