Water based fire suppression systems utilize the inexpensive and readily available medium of water to discharge onto flames through a normally fixed piping system.
There are different ways in which fire hydrant systems can be installed based on the application and site requirement. The hazard / risk to be protected will determine the most suitable type of system you need. A fire fighting system that is property installed and maintained can provide protection against loss of life and property in the event of a fire.
A Dry Pipe Sprinkler System, as are the other systems noted above, is a automatically operated sprinkler system. is a fire-protection system which utilizes water as an extinguishing agent. The system piping from the Dry Pipe Valve to the heat actuated sprinklers is filled with pressurized air or nitrogen. The system enables the system piping to remain dry until an automatic sprinkler is actuated.
A Dry Pipe System is primarily used to protect unheated structures or areas where the piping may be subjected to freezing. The system can be installed in any structure to automatically protect the structure contents and/or personnel from loss due to fire as with a wet pipe sprinkler system. When a fire occurs, the heat produced will operate a sprinkler causing the air pressure in the piping system to escape. When the pressure trip-point is reached, the dry-pipe valve opens allowing water to flow through the system piping and through the actuated sprinkler. At the same time a water motor alarm or electric pressure switches to sound an electric alarm. The water will continue to flow and the alarm will continue to sound until the system is manually shut off.
