POWER DRIVEN SYSTEM
The Standard One Seven®stationary system results of the combination of a compressor, a pump, a foam module and discharge devices (monitors, handlines, rotors, nozzles) managed by a control unit.The system can either be installed in the facility or delivered ready to use in a container.
The power of the system will be designed by One Seven® engineers according to each particular need of the customer.
STORED ENERGY SYSTEM
The “Stored Energy System” of One Seven® is a complete firefighting system that is driven without pump and compressor. The system consists of the components:
- Foam generator
- Pressure water tank
- Foam tank
- Nitrogen cylinder bank
- System control
Nitrogen from cylinder banks is used for generating compressed air foam. The required water is stored in the pressure water tank and it is also be charged with pressure via the nitrogen and that adds it to the foaming process in the correct pressure ratio.
The application of this system is provided for locations where the power supply is insufficient for operating a pump or compressor. Only the system control is supplied with power. It is also possible to design the system with a pump for generating the required water pressure and the nitrogen cylinder bank is only be used for generating the compressed air foam.
This system is often applied at heliports. However, it could also be applied at any other location. The operating time of the system is limited due to the limited volume of nitrogen and water. The required operating time will be determined according to the object to be protected and the required application rate so that efficient fire extinguishing can be realised.
