General Overview

overview : Clean Agent Systems Clean fire extinguishing agents include halon, halon replacements and inert gases. These gases are used in total flooding extinguishing systems to avoid lethal conditions for occupants given that the proper design and installation of such systems. The primary distinction between carbon dioxide and clean agents is the toxicity of the […]

High Volume Remote Controlled Monitors

Overview: High Volume Electric Actuated Remote Control Monitors from WILLIAMS FIRE & HAZARD CONTROL are designed to be mounted at elevated positions for fixed applications.  They have a programmable oscillation capability for automatic operations, but may also be overridden with a matched Hydro-Foam™ nozzle operated remotely through the use of a joystick and switches on a […]

Ranger Automatic Hydro-Foam Monitor Nozzles

Overview: The HYDRO-FOAM Ranger Nozzles from WILLIAMS FIRE & HAZARD CONTROL are advanced firefighting nozzles. They incorporate the effective range of an automatic nozzle with the exclusive combination of self educting/selectable constant meter­ing foam proportioning. Rangers 1.0, 1.5 and 2.0 deliver water flow ranges of 250 gpm to 1,000 gpm (946 Lpm to 3,785 Lpm), […]

Ranger Automatic Hydro-Chem Monitor Nozzles

Overview:  All Ranger Monitor Nozzles feature constant pressure modulation. These nozzles can flow water or water/foam solution generated by various proportioning methods from 250 gpm to 2,000 gpm (946 Lpm to 7,571 Lpm) depending on model number. The nozzle tip pressure is automatically main­tained at approximately 100 psi (6.9 bars) to assure maximum effective reach […]

Ranger 3 and 3 Nozzles

Features: Advanced Hybrid Nozzle Technology: The Ranger 3 nozzle has the unique capability to function as either an automatic pres­sure or fixed flow nozzle. HYDRO-FOAM Self-Educting Proportioning: The Ranger 3 and 3+ nozzles provide easy and efficient foam application through the HYDRO-FOAM capability which automatically proportions foam concentrate at a nearly constant percentage throughout the […]

Williams Portable Around the Pump Foam Proportioning System WATP-1500

Features: Operates against pump intake pressure up to approximately 33% pump discharge pressure. Example: pump discharge pressure of 150 psi (10.3 bar), intake pressure of 50 psi (3.4 bars). n Selectable proportioning rates between 0.25% and 6% suitable for municipal and industrial applications. Proportions up to 4,000 gpm (15,140 Lpm) of foam solution at 1%. […]

Ratio Controllers

Overview: Ratio Controllers are modified venturi foam proportioners that accurately meter pressurized foam concentrate into the firefighting water stream.  These foam proportioners are used in conjunction with balanced pressure systems, such as bladder tanks and pumped proportioning skids.  In operation, firefighting water flows through the modified venturi, creating an area of lower pressure, which is […]

Inline Eductors

Overview: Inline Foam Eductors provide the simplest and most economical method of introducing a metered flow of foam concentrate into a pressurized water stream.  As opposed to “Hydro-Foam™ Technology” which is used in union with master stream nozzles, these “Venturi-Type” foam proportioners are designed to be used in conjunction with a matched constant flow end-of-line […]

LW Series Foam Chambers

Overview: 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.  The foam chamber is installed inside a flammable liquid storage tank above the product’s highest liquid level.  The chambers are designed to meter foam flow, then gently expand and […]

LW Series Dual-Agent Foam Chamber

Overview: LW series dual-agent chambers combine both foam and dry-chemical applications to the internal fire. First a foam application will extinguish and secure the surface fire, then a secondary dry-chemical discharge dispels any residual flammable vapor above the foam blanket rendering the internal space inert thus allowing safe follow-up risk mitigation and recovery operations.  These […]
