Automatic Water Extinguishing Systems Automatic Water Sprinklers

Automatic water extinguishing systems (automatic water sprinklers) are systems designed to combat fires immediately and effectively by automatically spraying water when a high temperature or fire is detected. These systems reduce the spread of a fire and control it in its early stages, thus protecting lives and property.

Wet system

The wet system is an automatic water extinguishing system that relies on automatic water sprinkler heads connected to a network of pipes filled with water at all times, relying on a reliable water source. When the heat generated by the fire is sensed, the heads in the specified area are affected, opening to allow water to flow directly to extinguish the fire. It is used in buildings and spaces that have normal and non-extreme temperatures, where the water temperature inside the pipes is not less than 4 degrees Celsius and does not exceed 70 degrees Celsius. It is also preferred in systems that require limited pressure, making it an ideal choice for residential and commercial areas that are not exposed to extremely cold or hot weather conditions.

Dry system

Dry system, the system consists of automatically operated water sprinkler heads connected to a network of pipes filled with air or compressed nitrogen. In the event of a high temperature, the nitrogen or compressed air flows outward, and thus the network is filled with water and flows from the open sprinkler heads. The dry system is used as a fire extinguishing system in areas and spaces exposed to freezing such as coolers and freezers (space temperature is less than 4 degrees Celsius) or in areas with high temperatures such as sheds (space temperature exceeds 07 degrees Celsius) or systems that require pressure exceeding (21.01) bar, as well as systems where the water temperature exceeds (94) degrees Celsius.

Backward system

The back-end system relies on automatic water sprinkler heads connected to a network of pipes filled with compressed or non-compressed air, with an automatic alarm system connected to a main control panel. When heat, smoke or flame detectors are sensed, the system sends a signal to the pre-emptive valve to allow water to pass through the pipes and flow from the heat-affected heads. This system is used in sensitive areas where sudden water flow is feared, such as computer rooms, laboratories and libraries, or in locations containing high-value assets, as it provides accurate and effective protection while minimizing the possibility of water damage. In addition, the system allows for easy periodic maintenance to ensure its continued readiness.

Total immersion system

Total flooding system, the system consists of open water sprinkler heads (without bulb) connected to a network of pipes supplied from a water source through a valve called the flood valve that opens by the operation of the alarm system located in the same area protected by the flooding system. The total flooding system is used as a fire extinguishing system in occupations and areas that require large quantities of water to extinguish in a short time and in occupations where the ignition speed of the available materials is high such as liquefied gas tanks, flammable liquids, aircraft hangars and electrical transformers. The alarm system that operates the flood valve is either mechanical using water or mechanical using air or using electricity
