Proportioning Equipment


Proportioning is the introduction of foam concentrate into a flowing stream of water to produce a foam solution. Although there are several methods of proportioning, fixed foam systems typically use balanced pressure proportioning equipment.

Bladder Tank Systems


Bladder tank systems use a pressure-rated tank containing a nylon reinforced elastomeric bladder to store the foam concentrate.Bladder tank is one component in balanced pressure foam proportioning system. It needs no external power, other than water pressure to ensure correct operation. Bladder tank systems use a pressure-rated tank containing a nylon reinforced electrometric bladder to store the foam concentrate.

Type of Foam Concentrate


Typical foam concentrate types are the following:
1-Aqueous Film-Forming Concentrate (AFFF)
2-Film-Forming Fluoroprotein Foam Concentrate (FFFP)
3-Alcohol-Resistant Foam Concentrate ,used for fighting fires on materials usually destructive regular AFFF or FFFP Foams as well as involving hydrocarbons.
4-Fluoroprotein Foam Concentrate
5-Synthetic Foam Concentrate

Bladder Tank System


Statcon has a vide experience to design fabricate and hand over a balanced pressure proportioning systems which equalize the foam concentrate pressure with the water pressure at the intake of the foam proportioner. The foam concentrate pressure can be provided either by a pump or from the system water pressure. System water pressure is used to squeeze the bladder providing foam concentrate, at the same pressure, to the proportioner. With bladder tank systems, no external power source is required.The Final product will be in accordance to the UL and FM code requirements.

In-Line Proportioners


StatCon design In-Line Proportioners ( referred to as eductors ) which use the water flow to generate low pressure in a constriction in the proportioner, through which the foam concentrate is induced. They are reasonably priced, but unlike proportioners with automatic adjustment, they have a fixed flow rate and a small operating range. Foam eductors use the Venturi principle to draw foam concentrate into the water steam.

Balanced Pressure Proportioning System Pump Skids


StatCon engineers design and develop the engineering work for the Pump skids (or balanced pressure pump proportioning systems) are used in combination with atmospheric storage tanks which are typically of polyethylene or fiberglass construction. While foam concentrate is pumped from the storage tank to the proportioner, an automatic pressure balancing valve regulates the foam concentrate pressure to match the water pressure.

Discharge Devices


Discharge devices produce expanded foam and direct the flow at the point of application. Some foam discharge devices are special air aspirating devices which mix air with the foam solution to form an expanded mass of bubbles. Non ‚Äďaspirating devices may be used with certain low-expansion foam agents which do not rely on a thick blanket foam to achieve extinguishment.

In Line Balance Pressure Propoertioners


In-line balanced pressure proportioners are similar to pump skids, except that the proportioning assembly, including the automatic balancing valve, is remote from the pump and storage tank. A pressure control valve is added to the foam concentrate return line to maintain a constant pressure to the proportioner. Multiple assemblies can be supplied from a single tank and pump to protect several hazard areas.

Foam Monitors


Foam monitors are designed to control the horizontal and vertical directions of large capacity discharge streams. Water-oscillating monitors will automatically move side-to-side using water pressure as the energy source. Remote controlled monitors use an electric joy-stick tied into a hydraulic system. Other monitors are operated manually using a tiller bar to control direction and elevation. Various aspirating and non-aspirating nozzles are also available for use with monitors and/or handlines.StatCon has designed many Mobile Foam monitor system,For more information. ,please Consult StatCon Engineers.

Sprinkler Heads


Sprinkler heads are available from various manufacturers in both non aspirated and aspirated versions. Non aspirated heads with AFFF agents are more economical and can be used in either open deluge or closed-head sprinkler systems. Aspirated sprinkler heads are required for protein and fluoroprotein foams in deluge systems.

Foam Chambers and Foam Makers


Foam chambers and foam makers are air-aspirating devices designed to protect flammable liquid storage tanks. Foam chambers apply expanded foam gently down the inside of the tank wall onto the liquid surface. High back-pressure foam makers inject expanded foam through the tank wall near the bottom of the tank allowing foam to gently rise to the surface. Other types of foam makers are installed in the foam distribution piping where expanded foam is directed to specific hazards such as dike areas or floating-roof tank seal areas.

Foam Generators


Foam generators deliver large quantities of foam by expanding foam solution in the range of 200:1 to 1000:1. The high-expansion generator operates by coating its screen with high-expansion foam solution while air is blown through the screen to produce expanded foam. Because of its high expansion ratio, little water is required to generate large quantities of foam thereby reducing the potential for hazardous run-off or water damage. Foam generators are water-powered and require no other sources of power.
