The Hot Shot II balanced pressure foam proportioning system is a hydraulically driven “demand” system utilizing a positive displacement foam pump and pressure control circuit that provides foam concentrate supply at a pressure balanced or matched to that of the fire water pump.
For mounting a monitor onto any fire hydrant to create a convenient monitor station.
Inline Foam Eductors provide the simplest and most economical method of introducing a metered flow of foam concentrate into a pressurized water stream
LW series dual-agent chambers combine both foam and dry-chemical applications for internal floating roof tanks.
LW Series Foam Chambers consist of a foam expansion chamber and an integral foam maker, defined by NFPA 11 as “Type II” top-side application device.
Nozzle has a built-in self-educting foam proportioning capabilities and has a fully adjustable discharge pattern going from straight stream to full fog with flow rate of 150 or 225 gpm (568 or 852 Lpm) @ 100 psi (6.9 bars).
The LW9/WSDB Foam Makers are integrated systems providing NFPA 11 “Type II” foam application to the rim seal area of open floating roof tanks.
The LWNS series monitor nozzles are patented water powered nozzle systems that proportions and delivers either water or foam to the hazard area. Three models are available with flows at 350, 500 or 750 gpm (1,325, 1,893 or 2,839 Lpm) @100 psi (6.9 bars), respectively.
Minuteman Series Hose Reel Foam Stations are pre-engineered firefighting systems consisting of a foam concentrate storage tank, proportioning equipment, and hose and discharging devices.
The Multi-Port Metering Valve offers the simplicity and reliability of fixed orifice metering coupled with the flexibility of eight air actuated ports. The valve can be custom configured to have from 1 to 8 ports. Each port can be selected to meter solution flows from 30 gpm (114 Lpm) @ 3% up to 750 gpm (2,893 Lpm) @ 6%.
Williams’ “PKW™” is a highly specialized siliconized Purple-K that is one of the most effective dry chemicals used to extinguish flammable and/or combustible pressurized liquid fires. When used in conjunction with Hydro-Chem™ Technology it effectively controls and extinguishes pressurized or three dimensional “Class B” liquid fires.
The Williams Point & Shoot System includes both an air aspirating foam device designed to be installed on flammable liquid storage tanks for protection against a seal fire, as well as an optional fixed pipe to be used with a monitor and nozzle. Designed for flows up to 275 GPM (1040 L/min), a single air aspirating device delivers expanded foam solution through left, right, and against the wall discharge points.
The Powder Keg Dry Chemical Skid from Williams Fire & Hazard Control represents a powerful tool in a small, convenient package used to combat pressurized fuel fires. The package is designed to be mounted in a compartment of a fire truck. The system is packed with 75 lbs (34 Kg) of PKW™ dry chemical powder and powered by conventional 4,500 PSI air-pack bottles that can be easily replaced or recharged.
The Quick Attack foam cart is ideal for spill fires in chemical plants and flammable liquid storage areas. Unlike eductor style foam stations, this foam cart operates effectively and proportions foam even at low water inlet pressures. Minimum recommended inlet pressure is 70 psi (4.8 bars). Foam stream projects from monitor approximately 50’ (15.2 m) at 70 psi (4.8 bars) inlet pressure (straight stream in still air).
The Ranger 3 and 3+ Nozzles, featuring “Smart Nozzle” Technology, is capable of discharging water only, a water foam solution with Hydro-Foam technology using jet pumps or utilizing the automatic self-educting feature with constant/selectable metering, or dry chemical using the Hydro-Chem™ technology. Flow rates are available up to 4,000 gpm (15,100 LPM).
Mobile monitor trailer capable of delivering up to 4,000 GPM (15,100 LPM) water or foam solution. With its optional Hydro-Chem capability, it can deliver dry chemicals to extinguish 3-dimentional fires or pressurized gas fires.
The “Ranger 3™” and the “Ranger 3 PLUS” monitor nozzle packages are capable of self-educting foam concentrate, and can do so while maintaining a nearly constant pressure and a constant foam percentage (1% or 3% selectable) regardless of the flow rate.
These nozzles can flow water or water/foam solution generated by various proportioning methods from 250 to 2,000 gpm (946 to 7,571 Lpm), depending on model number, while maintaining a nominal 100 psi (6.9 bars) ± 10% to assure maximum effective reach of the water/foam solution over the flow range. The nozzle discharges dry chemical at approximately 20 lbs/sec (9 Kg/sec) through the center of the water/foam stream.
An automatic nozzle with the exclusive combination of self educting/selectable “constant metering” foam proportioning. Rangers 1.0, 1.5 and 2.0 deliver flow ranges of 250 – 1,000, 500 – 1,500 and 750 – 2,000 gpm (946 – 3,785, 1,893 – 5,678 and 2,839 – 7,570 Lpm), respectively while automatically maintaining the tip pressure at a nominal 100 ± 10 psi (6.9 bar) throughout their entire flow range.
Ratio Controllers are modified venturi foam proportioners that accurately meter pressurized foam concentrate into the firewater stream. These foam proportioners are used in conjunction with balanced pressure systems, such as bladder tanks and pumped proportioning skids.
