Correct identification of risk
Monitor position
The dominant wind in the region
Turbulence as a result of combustion
Environmental factors (other facilities…)
Safety of users
Minimum operating pressure of the monitor
Monitor flow rate
Monitor Nozzle flow rate
Fog/Jet or different nozzle requirement
Among the requirements mentioned above, especially establishing the correct Pressure and Flow relationship and adapting this situation to the area to be protected requires serious product knowledge and field experience. The nozzle and monitor to be used in the field must be selected correctly.
Monitors can be grouped into types that can use water or water and foam, as well as portable or fixed types.
Portable Monitors
Manual Operated Monitors
Self-oscillating Monitors
Fixed Monitors
Manual Operated Monitors
Self-oscillating Monitors
Hydraulic Operated Monitors
Electrically Operated Monitors
Fixed monitors are the most preferred and can be supplied relatively economically. Self Oscillating or Remote controlled monitors can be preferred according to the risk requirements of the site.
Monitor Nozzles
Direct solid-jet nozzle
Aspiration nozzle
Non-aspirating fog/jet nozzle
can be defined as three types. Solid-jet nozzles are specifically designed to use only water from monitors.
The throwing distances of Fog/Jet and non-aspirated nozzles are longer than aspirated nozzles for equivalent flow and pressure. They are especially preferred in areas where combined water and foam use is in question. Aspirating nozzles are preferred when direct foam use is required. In aspirating nozzles, the solution and air meet in the monitor barrel and the finished foam (expanded foam) is ejected from the barrel. Relatively shorter firing distances. It is recommended to use film-forming foams with non-aspirating Fog/Jet nozzles.
The performance of the monitor to be used can be measured according to capacity and effective throw distance. Generally, water and foam monitors that can use water and foam are selected according to your area of use for flow rates of 1,000 – 50,000 l/min. at a throw range of 30 – 120m. Although these values vary according to manufacturers, water and foam monitors operating in the range of 1,000 – 12,500 l/min. are often used in industrial sites. Water and foam cannons with high capacities are selected for special cases.
Depending on the intended use and hazard group, the nozzle type of the monitor is determined. The nozzles used in monitors can be supplied as direct jet nozzles or fog/jet nozzles. Nowadays, monitors are often selected to include fog/jet nozzles as they provide better firing range. If the selected Fog/Jet nozzles have the ability to calibrate the flow rate in the barrel of the nozzle, the installation will be extremely flexible and efficient.
The use and location of the monitor is the most important criterion that determines how the monitor should be controlled. Depending on your requirements, water and foam monitors can be used to suppress fires in a wide variety of high-risk areas.
