Water deluge fire protection systems are used in situations where large amounts of water are needed. There are three general categories for deluge applications:
- Direct Extinguish: water is sprayed directly onto the flames to control the blaze and extinguish the fire. Commonly used in emergency situations.
- Flame Control: water is sprayed to control the spread of a fire but not extinguish it. This is commonly used in gas leak situations where the gas continues to be consumed by the flame until the flow of gas can be turned off. Extinguishing these types of fires before turning off the gas flow can allow a build-up of flammable gas that can lead to an explosion.
- Cooling: water is sprayed onto the exterior surface of vessels that are under pressure and / or contain volatile materials. The water keeps the contents cool thereby preventing the contents from increasing in pressure. Commonly used in tank farms and on any vessel where catastrophic failure might occur from overheating.
Common Nozzle Types: Spiral
Common Spray Patterns: Full cone
Common Materials: Brass, Stainless Steel, Nickel/Aluminum/Bronze (NiAlBr), Titanium (salt resistant)
Selecting a Water Deluge Nozzle:
- BETE N series nozzles are UL/FM approved, carry Lloyd’s Register approval, and are suitable for use in NFPA 15 compliant systems. Certain nozzles in the N series are also approved by the Coast Guard for use on board ships.
- Preferred BETE models: N, MaxiPass, TFXP, TF, TFXPW, FF
- Important factors to consider: flow rate, area, coverage, spray angle.
- Our experienced engineers can help determine which nozzle is best for your application.
- Due to liability issues and safety concerns, BETE is able to size nozzles for fire protection systems based on specified nozzle criteria (coverage, coverage density, etc.). BETE cannot design the fire protection system itself.
