PRESSURE PROPORTIONING SYSTEMS
ADVANTAGES
- Optimally calibrated ex works, no calibration effort for the user
- Automatic adjustment of proportioning rate when foaming agent is changed
- Automatic adjustment of flow volume in case of viscosity change
- Automatic priming and automatic rinsing incl. drainage
- Monitoring of all relevant parameters, functional reliability due to emergency programs
PORTABLE PROPORTIONING SYSTEM
The portable One Seven proportioning system OSP-24i-T is an electrically driven positive pressure proportioning system for conveying 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 construction with robust frame and protective housing allows the use under rough operating conditions. The proportioning of the foaming agent is highly precise and provides constantly optimal proportioning rates, independent of varying flow rates, pressure and backpressure. Thus, this proportioning system is a technologically modern alternative to replace Z-proportioners still used by many fire departments.
ELECTRICALLY DRIVEN POSITIVE PRESSURE PROPORTIONING SYSTEMS
The electrically driven One Seven positive pressure proportioning systems are used as permanently installed systems in municipal fire engines. With a delivery rate between 0.2 l/min and 48 l/min the optimum amount of foaming agent can be added to the water for all possible firefighting operations. Optional equipment such as changeover valves for multiple foaming agent inlets, connections for tank filling pumps and level indicators, and water sensors for various flow rates are available for all positive pressure proportioning systems.
