A hydro fire mitigation system is provided that is associated with a structure. The system employs a number of sensors that detect an oncoming fire, which directs a controller to initiate fluid flow through a number of sprinklers. The system is fully autonomous and does not require municipal water or power during use.

Certain aspects relate to an apparatus for fire protection to a peak of a roof of a structure including a fire-retardant conduit mounted to the peak of the roof. The fire-retardant conduit includes a channel having sidewalls, each sidewall including a top portion having a lip; a channel windbreak configured to cover the channel and the lip of the channel; and a fire-retardant source pipe coupling the fire-retardant conduit to a fire-retardant source to supply fire-retardant into the channel.

A dry sprinkler includes a flexible tube section that maintains a pressurized fluid, such as a liquid antifreeze solution, between a first end and a second end. A first seal prevents fluid from a supply line from entering the flexible tube section. The first seal is maintained in a sealed position by a pressure of the pressurized fluid. A sprinkler head is coupled to the second end of the flexible tube section, and includes a frame, an output orifice, a deflector, a second seal that seals the output orifice, and a thermally responsive element configured to maintain the second seal in a sealed position when the thermally responsive element is in a non-responsive state. A differential pressure controller maintains a ratio between the pressure of the pressurized fluid in the flexible tube section and a pressure of a supply fluid in the supply line to at least a certain ratio.

The invention relates to an extinguishing nozzle of a fire extinguishing installation for selectively identifying and fighting fires in at least one protected area, and to an associated fire extinguishing installation and to a method for operating an extinguishing nozzle. The extinguishing nozzle comprises i) a communication unit which is configured for communicating with a fire detector and/or extinguishing control station of the fire extinguishing installation, ii) a control element which is configured for controlling the extinguishing nozzle, wherein the extinguishing nozzle is connectable to at least one fluid line and the control element is configured for selectively enabling and/or shutting off a passage of an extinguishing fluid, which is flowing in the fluid line, through the extinguishing nozzle, and iii) an energy harvester which is configured for providing energy for at least the communication unit and the control element by means of energy harvesting.

Antifreezes are provided for deployment in wet sprinkler systems located in cold environments. The antifreezes allow for the wet sprinkler system to be actuated under temperatures below 32° F. Wet sprinklers, sprinkler systems, methods of providing for the control, suppression and/or extinguishment of a fire that occur in a cold environment, and methods of preventing wet sprinklers from freezing also are provided. The sprinklers, sprinkler systems and methods can be used in residential, commercial and storage settings.

A corrosion monitoring device for pipe systems according to one aspect of the present disclosure includes a pipe having a first pipe portion and a second pipe portion. The first pipe portion includes a wall having a first wall thickness, and the second pipe portion includes a wall having a second wall thickness that is greater than the first wall thickness. The corrosion monitoring device further includes a structure coupled to the pipe and defining a sealed chamber between the structure and at least the first pipe portion, and a sensor a pressure in the sealed chamber or for sensing a liquid in the sealed chamber. Example corrosion monitoring devices and methods for monitoring corrosion in pipe systems are also disclosed.
