Deluge system in fire fighting

How is deluge system worrk? Deluge Fire Sprinkler System A deluge fire sprinkler system is similar to a pre-action system except the sprinkler heads are open and the pipe is not pressurized with air. Deluge Systems are named from the ’deluge’ of water they provide when activated.

When the system detects heat and or fire , the deluge valve will release water, dry chemicals, inert gases, or foam. NAFFCO offers deluge systems with a variety of options from deluge valves and fire nozzles system to medium and high velocity water spray nozzles for industrial fire safety services.

For High Hazard Occupancies Needing Rapid Suppression. This massive release of water is needed in areas such as aircraft hangars, fuel loading facilities, power plants, and chemical and hydrocarbon storage or processing facilities. Operation - Activation of a fire alarm initiating device , or a manual pull station , signals the fire alarm panel , which in turn signals the deluge valve to open, allowing water to enter the piping system. How deluge system worrk MEP. Water flows from all sprinklers simultaneously.

Designed to fight fires in high hazard areas like process, turret and wellhead. Deluge is an open nozzle system , meaning ALL nozzles in the protected area are released simultaneously. When the deluge system is triggere a massive amount of water is released very quickly, making it an extremely effective way to extinguish fire.

NAFFCO is the leading supplier of deluge systems in Dubai and the Middle East. We will customize our systems with a range of options like deluge valves, spray nozzles and more. The system is connected to a water supply through the deluge valve.

Deluge systems operate similarly to Preaction systems and are not pressurized with air. This valve is opened by the operation of a fire detection system installed in the same areas as the open sprinklers or nozzles. Let us take an example to be more specific and clear. To avoid this kind of fire , we use Water Spray System.

Deluge ’s fire detection and suppression offers comprehensive fire protection solutions to meet the business and protection needs of our clients. A deluge system is similar to other types of sprinkler system except that the chemical is released through open discharge devices rather than spray heads. This fire suppression system is activated by smoke or heat detectors and releases a flood of foam instantly from an open sprinkler, nozzle, or foam generator. Our services includes engineering, procurement and construction contracts of fire protection system. Foam water systems generally work by allowing foam concentrate to mix with water flowing into the piping system.

These systems are equipped with a bladder tank containing foam. When a fire is detected a signal is sent to the releasing panel to open the deluge valve allowing water to flow. They are commonly used in fixed fire protection systems whose pipe system is empty until the deluge valve distributes pressurised water from open nozzles or sprinklers.

A deluge system consists of a network of dry pipework and open nozzles that is connected to a water supply through a normally closed on-off or a pressure regulating deluge valve.

DIFF Systems A Deck Integrated Fire Fighting (DIFF) system is an effective fire suppression system that is normally the primary firefighting system on a helideck. Flexible hoses are provided to connect TrimPac to the deluge valve. Depending on the project requirements, there are several possible flow control activation solutions including electric, electro-pneumatic and hydraulic on which additional features such as automatic pressure reducing and remote ON-OFF trims can be added. Aspecial deluge valve holds back the water from the piping, and is ac- tivated by a separate fire detection system. A foam deluge system is triggered by alarms like smoke or heat detectors.

A deluge system also has open nozzles which can be put in use whenever a hazard is detecte for instance when flammable liquids are spreading across the floor. Deluge Water Spray SysteAn automated water spray system where the water distribution piping is equipped with open spray nozzles for discharging over a protection area or equipment.
