The OS-5500-020-B is our standard PTO-driven One Seven system for installation in municipal frontline fire appliances. The maximum One Seven foam volume is 5,500 l/min, the flow capacity for water/ wetting agent is up to 2,000 l/min. The system´s working pressure is 8 bar. The system is fitted with two (2) 2.0´´ One Seven compact foam generators which allow the simultaneous operation of one wet foam and one dry foam outlet, e.g. in case of exposure protection combined with firefighting operation. The OS-5500-020-B can supply two (2) 3.0`` discharge outlets with a foam flow of up to 2,800 l/min (400 l water, 2,400 l air) each. The system allows the simultaneous operation of up to six (6) One Seven hand lines, respectively a monitor with a foam flow rate of up to 5,500 l/min. In combination with the unique One Seven foaming agents the OS-5500-020-B is a reliable and effective weapon against all kinds of fire.

The portable One Seven proportioning system OSP-24i-T is an electrically driven positive pressure proportioning system to deliver and admix foaming agent to water. Up to six nozzles can be supplied with wetting agent simultaneously via manifolds. When using appropriate foam nozzles low expansion foam and medium expansion foam can be produced. The OSP24i-T can be carried comfortably by two persons and thus be located and used very flexibly. The construction with robust frame and protective housing enables the use under rough operating conditions. 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*s. Of particular interest is the possibility of using modern „highperformance“ 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

The One Seven proportioners are electrically or hydraulically driven positive  pressure proportioning systems. They are used to convey foaming agent and add it to the extinguishing water. The foaming agent is metered automatically and highly accurate on the basis of the required proportioning rate and the currently measured water volume flow. Deviations in the calculated delivery volume (e.g. due to change of discharged water or viscosity changes of the foaming agent) are detected and automatically corrected by modern sensor technology. The One Seven positive pressure proportioning systems are controlled intuitively via a modern color display with touchscreen.

​All essential functions of the One Seven proportioning systems are covered by emergency programs which can be started as quickly as possible at the push of a button if necessary.

​Several optional equipment is available for the One Seven positive pressure proportioners e. g. tank filling pumps, tank level indicators and changeover valves for up to three foaming agent tanks.

​All proportioning systems comply with the European standard EN 16327 and are available in various performance classes with maximum flow rates of 16 l/min, 24 l/min, 32 l/min and 48 l/min.

ADVANTGES

• 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

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.

HYDRAULICALLY DRIVEN POSITIVE PRESSURE PROPORTIONING SYSTEMS

The hydraulically driven One Seven positive pressure proportioning systems are designed to convey large quantities of foaming agent from 10 l/min and admix it to the extinguishing water. Accordingly they are mainly used in powerful industrial fire engines or in large fixed extinguishing systems. Optional additional equipment is available for all hydraulically driven proportioning systems, such as changeover valves for several foaming agent inlets, connections for tank filling pumps and level indicators, and water sensors for various flow rates.

HIGHLY EFFECTIVE FORMULA

The exceptional, constant and always reproducible bubble structure of One Seven® foam is the result of a perfect interaction between the chemical properties of One Seven® foaming agent and the One Seven® foam generator. Precisely and reliably adjusted proportioning rates in the systems guarantee an optimal extinguishing and cooling effect of the One Seven® foam. This results in unique extinguishing foams that differ significantly from conventional foam.

 All One Seven® foaming agents were developed with the protection of people and the environment in mind. There is no risk of injury even in case of skin or eye contact with One Seven foam®. To protect the environment many One Seven® foaming agents do not use fluorine – without any loss of performance in firefighting. 

The optimal proportioning of foaming agents is determined by the proportioning rate. It indicates the percentage of foaming agent which must be contained in the water/foaming agent solution. In the One Seven systems the proportioning rate is preset, automatically monitored during operation and automatically adjusted if necessary.

Less achieves more
The proportioning rate of a foaming agent has an important influence on the operating time of a firefighting engine or a fixed extinguishing system. Therefore One Seven foaming agents are highly concentrated liquids that allow particularly low proportioning rates.

Price is not equal to costs
The proportioning rates of foaming agents are directly related to the actual costs incurred: The lower the proportioning rate, the lower the consumption and the lower the application price. Highly concentrated foaming agents with low proportioning rates also save money in transport costs from the manufacturer, storage and handling due to the smaller quantities required. So: When making purchasing decisions it is important to take not only into account the purchase price but to consider all the costs associated with the foaming agent.

CLASS A
One Seven® Class A foaming agents have a particularly high penetration power so that the foam moisturizes class A materials quickly and deeply. The temperature inside the fire material is reduced, deep-seated pockets of embers are extinguished. One Seven® class A foaming agents are fluorine-free and quickly biodegradable. The proportioning rates are an extremely economical 0.3 % or 1.0 %.

CLASS B(FFF)

One Seven® foaming agent class B(FFF) is the only fluorine- and polymer-free foaming agent class B on the market with European approval for direct and indirect use (performance class I/B, according to EN 1568-3). The proportioning rate is economical 0.5 %.

CLASS B(AFFF)

One Seven® foaming agent class B(AFFF) is a water film forming concentrate. The foam spreads rapidly on the surface of burning liquids and forms a strong closed foam carpet. This smothers the fire and suppresses the formation of flammable gases. The proportioning rate is only 0.5 %. The foam concentrate is approved in Europe (performance class I/B, according to EN 1568-3), in the USA (FM 5130) and according to ICAO Level B.

CLASS B(FFF)-AR

One Seven® foam concentrate class B(FFF)-AR is alcohol resistant. Accordingly it is used for fires involving alcohol and liquids containing alcohol. The optimum proportioning rate is 3.0 %.
