Description
One Seven Portable Proportioning System
The OSP-24i-T Portable Proportioning System is an electrically driven positive pressure proportioning system for the delivery and admixture of foaming agent to water. It can be carried comfortably by two people and can therefore be used flexibly at any location.
The OSP-24i-T operates with high precision and always delivers constant, optimum proportioning rates – independent of varying water flow rates, pressure and back pressure. This makes it a technologically advanced proportioning system which can more than replace the old-fashioned Z proportioners.
The foaming agent is metered automatically and highly accurate on the basis of the preset proportioning rate and the currently measured water volume flow. Deviations in the calculated delivery volume (e.g. due to viscosity changes caused by temperature fluctuations) are detected by high-precision sensors and are automatically adjusted by the system. The integrated plunger pump is suitable for all foaming agents approved for firefighting up to a viscosity of 500 mPa.
The OSP-24i-T Portable Proportioning System is especially suited to modern high performance foaming agents with proportioning rates of economical 0.3 – 1.0%.
Intuitive operation is done via an integrated 5-inch color display with touchscreen. This display also shows the measured sensor data for system monitoring.
ADVANTAGES:
- No calibration effort necessary
- Highly precise proportioning, even at lowest proportioning rates
- Highly accurate and reliable flow metering
- No manual adjustment necessary when foaming agent is changed
- Always constant, optimum proportioning rate, even when viscosity changes
- Quick restoration of operational readiness due to automatic priming, rinsing and drainage
- Highest possible fail-safety, additionally covered by emergency programs
