FIRE DOS SYSTEM
This revolutionary proportioning system offers many advantages over other proportioning methods, such as: easy installation, operation through the water flow available in the system, easy adaptation to existing plants, saltwater-proof versions for offshore application, wide flow range, allows work with adjustable dosages, low pressure loss, and can be used with any type of foam concentrate (LGE).BP SYSTEM
The Balanced Pressure Proportioning Systems Model BP are the most common foam proportioning systems due to their versatility and dosing accuracy. Kidde BP systems are fixed units mounted on skids, offering foam protection for all types of hazards, both onshore and offshore. The skid includes a complete proportioning system, mounted on a base for installation on the client’s water piping.ILBP SYSTEM
The Balanced Pressure Proportioning System Model ILBP supplies foam concentrate (LGE) to the remotely mounted ILBP Proportioning Module, which accurately injects the correct dosage of LGE into the water supply network as needed. A skid-mounted pump is provided, fully assembled and ready for connection according to the client’s field piping. The unit consists of a foam concentrate pump, pump control panel, pressure sustaining valve, and all necessary piping, valves, and fittings mounted on a steel base.JET PUMP TERMINATOR PROPORTIONER
Jet Pump type proportioners are eductors that use pressurized water to draw foam concentrate (LGE) from drums, portable tanks, or fixed storage tanks. The Jet Pump proportioner is installed between fire hose lines and operates under high water flow. Water accelerates through a conical diffuser inside the proportioner, increasing speed and creating a negative pressure region.LINE PROPORTIONER (PL)
Line proportioners are designed to draw a controlled flow of LGE into the pressurized water line based on the Venturi principle. They provide lower cost for systems requiring fixed flow operation where water pressure is sufficient. Depending on the foam system design, the line proportioner can operate at low water pressure up to 75 psi (5.3 kgf/cm²). Most systems require water pressure between 125 and 200 psi (8.8–14 kgf/cm²).RCF PROPORTIONER
The RCF Model Proportioner is a bronze cast proportioner with flanged connections, designed to inject foam concentrate into a water supply line. It is compatible with all foam fire protection systems and automatically provides all types of foam concentrate across the designed flow range, regardless of pressure.RCT PROPORTIONER
The RCT Model Proportioner is a bronze cast proportioner with threaded connections, designed to inject foam concentrate into a water supply line. It is compatible with all foam fire protection systems and automatically provides all types of foam concentrate across the designed flow range, regardless of pressure.ILBP PROPORTIONING MODULE
The ILBP Proportioning Module consists of a proportioner (RCF or RCT), diaphragm valve with manual adjustment, duplex pressure gauge, manual ball valve, and gauge to verify LGE inlet pressure. All components are factory-assembled using corrosion-resistant materials and ready for installation in the client’s supply line. ILBP modules provide foam protection for multiple applications, including offshore.BALANCING VALVE
Balancing valves are integral to balanced pressure proportioning systems and are designed to balance foam concentrate and water pressures at the RC proportioners by controlling the foam concentrate pressure at the valve inlet. Balancing is achieved by adjusting the foam concentrate volume, returning excess to the LGE storage tank.3030 PROPORTIONER
The 3030 proportioner is designed to supply a self-educting nozzle with a large volume of LGE from a safe distance. It can supply 3% LGE at a flow of 1000 gpm from the nozzle at 120 meters distance using a 2½” hose with an inlet pressure of 200 psi (14 kgf/cm²).
