Fixed systems and method for extinguishing large scale industrial tank fires, with and without fixed roofs, and featuring aerated foam projecting nozzles and including fixed center directed nozzles.

A fire suppression nozzle assembly includes a nozzle having a first tube defining an axially extending passageway. The passageway includes a plurality of primary outlets disposed on a sidewall of the first tube. The nozzle also includes a second tube circumscribing the first tube to define a chamber. The primary outlets provide fluid communication between the passageway and the chamber. A sidewall of the second tube has a first set of radially facing secondary outlets axially offset from the primary outlets in a first direction and a second set of radially facing secondary outlets axially offset from the primary outlets in a second direction opposite the first direction. The nozzles disclosed herein are configured such that gas exiting a plurality of outlet holes is balanced.

A fire suppression system includes an inert gas source to supply inert gas to an enclosure via distribution piping. The system includes a fire suppression nozzle that is installed in the enclosure. The nozzle includes an inlet that connects to the distribution piping and includes a plurality of outlet holes. During discharge of the inert gas, the sound power level from, the nozzle is no greater than 125 dB for a frequency range from. 500 to 1.0,000 Hz for a coverage area up to 32 ft.?32 ft. in compliance with UL 2127. The nozzles disclosed herein are configured such that gas exiting a plurality of outlet holes is balanced.

A spray nozzle and fan spray system is provided to aid in the cooling and extinguishing of electric vehicle fires. The spray nozzle is configured to be positioned underneath the vehicle, where water is evenly distributed along the underside of the vehicle through a plurality of holes disposed through the side and upper surfaces of the spray nozzle. Simultaneously a fan nozzle may be configured to spray fluid over the top of the vehicle and provides a heat barrier. A method of extinguishing an electrical vehicle fire is also provided that improves the safety of bystanders and fire fighters.

A valve structure includes a body defining an internal passage and including a discharge hole having a predetermined diameter, and a spray unit arranged to be movable in the internal passage and exposed to an outside through the discharge hole.

A nozzle positioning includes a primary pole, a grasping element supported on the upper end of the pole and configured to secure the pole to a surface, and a nozzle mount supported on the grasping element. The nozzle mount is configured to support a nozzle in a substantially horizontal position and to allow the nozzle to rotate about a longitudinal axis perpendicular to the horizontal upper surface of the grasping element. The grasping element is in the form of a hook configured to fit over a window sill or similar structure.
