A customer was designing awater deluge system to protect an11' x 40' x 8' high chemical tank.They needed complete coveragefrom 2 headers running parallelto the 40' long side.

BETEApplications Engineersprovided several spraytrajectories and the N series

was recommended because itoffered the proper combination ofcoverage and droplet size, as wellas industry approvals, such asFactory Mutual and UL.

BETE N series fire protectionnozzles are recognized acrossthe petroleum and chemicalprocessing industries as the

first choice in dry, fixed firesuppression systems. BETE Nseries nozzles are used routinelyin dry fire protection systemsprotecting offshore drilling rigs,LPG tanks, and LNG tanks, aswell as other types of vesselscontaining flammable liquids.

Water Deluge

BETEApplications Engineerssupplied spray pattern trajectorydata for the fire suppression sys-tem in the 1.8 mile long BurnleyHighway Tunnel in Melbourne,Australia. The data includeddifferent wind velocities toensure that the nozzles specified

would offer sufficient coverageover a number of different windvelocities in the tunnel to controla fire. The system uses a combi-nation of BETE N7W and N8Wnozzles constructed in type 316stainless steel.

In March of 2007, a serious autoaccident occurred that resulted ina fire in the tunnel. The sprinklersystem was activated and BETEN series nozzles succeeded incontrolling the fire.

Tunnel Fire Protection

BETE N series nozzles are FactoryMutual and Lloyd’s Registerapproved for fire protection, arequirement for operation outof U.S. ports. These nozzlesare used on ships with watersystems, often replacing olderCO2 based systems.

N series nozzles are also usedto protect outdoor escape routesonboard tankers and offshoreoil-drilling platforms. Predictedspray patterns and trajectoriesprovide estimated nozzlecoverage under various windconditions. Using this data, ourcustomers are able to determine

the correct nozzle mountinglocations.

BETE has supplied “Deck Edge”nozzles for U.S. Navy applications.The 3/4" NF300-80X and the3/4" NF300-80 have been used insprayingAqueous Film FormingFoam on the decks of aircraftcarriers.

The 1/2" TF29-180 was developedfor Navy magazine sprinklingon ships; it meets MilitarySpecification MIL-S-24660 (SH).The 180° full cone pattern reducesthe vertical clearance requiredbetween sprinklers and ordinancefrom 18" to 4".

Requirements for thermalradiation screening for personnelprotection on ships have been metmost effectively with the TF170or TF150 series nozzles. The TFnozzles provide better absorptionof thermal energy and dissipatesthe heat and energy from the fire.The multiple concentric conesprovide a barrier to air reenteringthe fire while also minimizingspray wind drift.

Marine

A customer was developing anew water wall protection systemon an oil rig to protect equipmentand personnel from the extremeheat generated by the naturalgas flare. The current systemconsisted of a few nozzles on theflare boom, but was inadequatefor the amount of heat generated.

BETEApplications Engineerssuggested a wide angle spiralwould be appropriate, specifi-

cally, the N5W to match thespecified flow rate. To confirmspacing, BETE modeling softwarewas used to determine spraycoverage trajectories from eachnozzle when sprayed horizontallyoutward. These trajectoriesprovided the customer theconfidence that the new designwould be more than sufficientto protect the rig.

U.S. Coast GuardApproved

BETE Product PerformanceWater Wall – Water is used as a barrierto shield against radiant heat, harmfulgases, and flames to provide protection forpersonnel and equipment.

Nozzles: TF150/170, N, FF, NF

TF150/170 – spiral nozzles with high flowrates, wide coverage in close proximity,multiple concentric cones; more effectivethan a fanN – spiral with narrower angles than theTF150/170; regulatory approvals for fireprotection applicationsFF – provides a wide, single sheet spraywith a 145°angle. Less effective coolingand barrier protection than spiral-type (TF,N) nozzlesNF – greater choice of angles than FF (15°up to 120°)

Water Deluge – There are two generalcategories for water deluge fire protectionsystems.1Direct Extinguish - Large quantities ofwater are sprayed over the flames to con-trol the blaze and extinguish the fire.

2 Cooling - Water is sprayed onto the exte-rior surface of vessels that are underpressure and/or contain volatile materi-als, cooling the vessel and preventing ex-plosion.

Nozzles: N, MaxiPass, TFXP, TF150, TFXPW, FF

N, TFXP, TF150, TFXPW – all spirals providea spectrum of drop sizes with concentricrings of larger droplet, high momentumspray containing fine droplets between therings. The high momentum, large droprings punch through the flame while thesmaller drops vaporize quickly, combiningmaximum flame penetration and heattransfer. This multiple cone strategy mini-mizes wind drift and prevents oxygenfrom reentering the spray areaN – spiral nozzle with advantages listedabove plus tighter tolerances to meet insur-ance approvals. Protective blow-off coversavailableMaxiPass – used when coverage diameteris more important than atomization andheadroom is adequate. The MaxiPass pro-duces larger droplets than an equivalentflow rate spiral causing improved wind re-sistance. High-pressure operation narrowsthe spray angle for greater penetration andresistance to crosswindsTFXP – spiral nozzle with advantages listedabove but with maximum free passageFF – used for surface or equipment protec-tion when relying on rundown for protec-tion is acceptable

Marine – Marine applications includedeluge, foam, and water wall systemswhere the nozzles are subject to extremeweather conditions and exposure toseawater.

Nozzles: TF29-180, SRWM, in addition towater wall and water deluge nozzlesTF29-180 – very wide coverage for limitedheadspace areas (such as storage rooms onships)SRWM – pop-up operation for deck cool-ing/protection/decontamination; usedwhere a permanently exposed nozzlewould be an obstruction

Halon Replacement – Professionalsare turning to fine water mist systems inlieu of environment-damaging Halon sys-tems. Exceptionally fine water droplets aresprayed over the fire where they evaporateand displace the oxygen, extinguishingthe fire. The low volume flow and highevaporation rate minimize water damageto sensitive equipment.

Nozzles: MicroWhirl, L, PJ, P, MicroWhirl Head

MicroWhirl - high-pressure nozzle produc-ing very low flow, extremely fine, mistingprotectionP, PJ – higher flows than the MicroWhirl;produces a very fine mist by means of anexternal impingement pinL - higher flows than the PJ with fineatomization

MicroWhirl Head – standard, stockmanifold for up to seven (7) individualMicroWhirl nozzles

Foam – The nozzles are used to spraylow-expansion foam, such as AFFF, ontoship decks and in smaller enclosed areas tohelp subdue the fire.Nozzles: TF, N, NF, NFX

TF, N – spiral nozzles are placed so that thespray is perpendicular to the surface to becoveredNF, NFX – flat fan nozzles are oriented tospray parallel and very close to the surfaceto be protected

Tunnel Fire Protection – Awell-designed fixed fire suppression system ina traffic tunnel protects against loss ofhuman life and minimizes structural dam-age in the case of a fire or explosion. Spiralnozzles can be more effective than tradi-tional sprinkler systems due to higherflame penetration by the multiple cones.

Nozzles: N, TFXP, TF150, TFXPW

N, TFXP, TF150, TFXPW – all spirals providea spectrum of drop sizes with concentricrings of larger droplet, high momentumspray containing fine droplets between therings. The high momentum, large droprings punch through the flame while thesmaller drops vaporize quickly, combining

maximum flame penetration and heattransfer. This multiple cone strategy mini-mizes wind drift and prevents oxygenfrom reentering the spray areaN – spiral nozzle with advantages listedabove plus tighter tolerances to meetinsurance approvals. Protective blow-offcovers availableTFXP – spiral nozzle with advantages listedabove but with maximum free passage

Water Mist – Water mist systems usea finely atomized, low flow water sprayto extinguish fire. They are ideal forprotecting assets that would otherwisebe destroyed by water damage in delugesystems.

Nozzles: MicroWhirl, L, PJ, P, MicroWhirl Head

MicroWhirl - high-pressure nozzle produc-ing very low flow, extremely fine, mistingprotectionP, PJ – higher flows than the MicroWhirl;produces a very fine mist by means of anexternal impingement pinL - higher flows than the PJ with fineatomizationMicroWhirl Head – standard, stock mani-fold for up to (7) individual MicroWhirlnozzles

Toxic Gas Mitigation – Water spraysystems are used to remove water soluble,toxic gases from the air in the event of anaccidental leak. These systems prevent thespread of hazardous vapor clouds. BETETF16FCN and TF20FCN nozzles werechosen for mitigation systems of accidentalreleases of hydrofluoric acid (HF) by theIndustry Cooperative Hydrogen FluorideMitigation Assessment Program.

Nozzles: TF, TFXP, N

TF/TFXP - finer spray nozzles with standardflow rates; good for scrubbing chemicalsN - spiral nozzle with advantages listedabove plus tighter tolerances to meetinsurance approvals. Protective blow-offcovers available

Dust explosion protection – Waterspray systems are used to prevent explo-sive combustion triggered by dust buildup or static electricity in storage tanks andtransfer conveyors for items such as coaland grain.

Nozzles: MicroWhirl, L, PJ, TF, SRWM

MicroWhirl, L, and PJ – fine mist with nowetting. Increases humidity and lowersstatic discharge riskTF – adding enough moisture to prevent/knock down dustSRWM – installs flush to the vessel walland extends when activated; used inextremely dirty or dangerous areas wherean exposed nozzle would be destroyed
