In line with regulations, the wet pipe system is designed for covering minimum 280 m² of the area which is the highest or farthest away from the pump, based on water discharge density as defined for the various deck heights. Open ro-ro spaces are those ro-ro spaces that are either open at both ends or have an opening at one end, Reliable system with large bore nozzles that reduce the risk of clogging, The systems use seawater and do not require extra fresh water supply during operation, To avoid corrosion and clean up after testing, the systems are connected to a fresh water supply, Standard tool- and spare part kits are available for commissioning and service to ensure efficient operations, Documentation for easy planning and design of the ro-ro space, Low pressure system using low pressure components and piping cost saving easy installation, A cost effective solution Designed for optimal system performance, keeping both installation and operational costs low, Standardised product range reduce delivery time, Minimal and easy maintenance keeps operational costs low. Usage. Deluge Fire Sprinkler System. AND COMMISSIONING OF DELUGE SYSTEM 1. DWG. Although many types of system are available, a basic foam system always requires foam concentrate storage, proportioning equipment, one or more discharge devices, and a manual and/or automatic means of detecting Refer to Figure 3 and 4 for positioning details. However, the systems cannot be combined in the same protected space. The systems shall suppress fires on open ended decks and in enclosed spaces where vehicles and passengers have access.The new regulations were introduced after several accidents with RoRo fires. The NFF XFlow wet pipe and deluge are designed to protect ro-ro and ro-pax vessels against fires.Open ro-ro spaces are those ro-ro spaces that are either open at both ends or have an opening at one end. As a consequence, the new MSC.1/Circ.1430 regulation reflecting the requirements for prescriptive and performance based systems from the SP tests was adopted. Electrical release deluge system This type of system consists of the fire alarm system, extinguishing line, deluge station and water source. When water is added as mist it is most efficient at reducing and dissipating heat and thereby controlling, suppressing and extinguishing a fire. Page 3 For Deluge Valves equipped with Conventional Deluge Valve Trim, follow steps 1 through 10 (and 11 & 12 if applicable) below. C. An automatic water supply provides water under pressure to the system piping. SYSTEMS are MANDATORY for all [NASA] [_____] assets and systems identified as Critical, Configured, or Mission Essential. Deluge systems are connected to a water supply through a deluge valve that is opened by the operation of a smoke or heat detection system. T. OTAL. READ PAPER. 94. In line with regulations, the deluge system is designed for simultaneous activation of two adjacent deluge sections that are highest or farthest away from the pump, based on water discharge density as defined for the various deck heights. The detection system is installed in the same area as the sprinklers. When the detection system is activated water discharges through all of the sprinkler heads in the system. (Refer TFP2180) These systems are very effective in hazardous areas because they release water or another fire suppressant to all the open sprinkler heads simultaneously. Deluge Valve used for fast application of water in a spray system. This paper. Deluge System Technical Manual for Operation, Maintenance, and Troubleshooting. Optionally, section valves can be controlled by fixed fire detection system. Deluge valve protects areas such as power transformer installation, storage tank, conveyor protection and other industrial application etc. The FDV-DC0 Deluge system is actuated electrically or pneumatically and resets locally. h�b```f``*``e`�� �� @1V����73?e�g�� A preaction system is similar to a deluge system except that automatic sprinklers are used, and a small air pressure is usually maintained in the piping network to ensure that the system is air tight. WATER Fp—694 e FP—414 Fp—413 FP—489 E Fp—56 Fp—561 IA—IA SUPPLY G—19Ø2ØØ SH. The protected space is divided into sections, each with a section valve located outside of the protected area. Deluge fire sprinkler systems are generally used for high hazard industrial and commercial applications, such as power plants, chemical processing facilities, and aircraft hangars, where high volume, high velocity suppression is necessary to prevent the spread of fire to other areas of the facility. When the detection device is activated, the deluge valve is tripped and water flows The FDV-DH1 Deluge system is actuated hydraulically and resets remotely. 14 Full PDFs related to this paper. The systems shall be designed for remote manual activation. The nozzles are fitted with a glass bulb, and are attached to a pressurized piping system, connected to water pumps.

Sheet 5 of 6. Pressure required for MV Nozzles 1.4 bar(g) and for HV nozzles about 3.4 barg for optimum performance. The NFF XFlow® deluge system is a dry pipe system primarily designed to protect open ro-ro spaces, using open nozzles attached to a piping system connected to water pumps. 88 0 obj <> endobj Two detection systems, can independently activate an actuator to open the deluge valve: a pneumatic Dry Pilot detection Line and/or an electric solenoid, connected to sensorsthrough a control Panel. The Viking deluge system can be activated by a hydraulic, pneumatic, electric, or manual release system or any combination of these release systems. When the Wet pilot detection line’s automatic fire sprinklers are subjected to flame heat and shatter-open, it enables the FDV control chamber to drain and de-pressurize, opening of the deluge valve and admitting water into the spray sprinkler system. By a wide margin, wet pipe sprinkler systems are installed more often than all other types of fire sprinkler systems. 16 8/2020 Automatic Extinguishing, Deluge and Preaction Sprinkler System Releasing Control 2.02 UNDERCAR DELUGE SYSTEMS . Deluge valve protects areas such as power transformer installation, storage tank, conveyor protection and other industrial application etc. 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. ... features of the system. Deluge systems are used for pro-tection against rapidly spreading, high hazard fires. The NFF XFlow Wet Pipe and Deluge Systems are designed for marine applications and delivered with necessary certificates and approvals. HBR2—8255LR. The detection system is installed in the same area as the sprinklers. Deluge Vs. Pre-Action Fire Protection Systems | Fire Protection Blog Droplets in variable sizes circulate in the airflow, suppressing the supply of oxygen and absorbing the heat energy, and thereby breaking the chain of combustion.Water is an effective agent for fire fighting as it is readily available and environmentally friendly.
