It is reasonably priced,and is always available in ad-equate volumes. Since water iscompatible with most other sub-stances, it is extremely versatilewhen used as an progressive modernization ofindustry and commerce not onlycalls for structural fire protectionand assistance from fire brigades;there is also a need for automaticfire protection SYSTEMS which canoperate on the machinery or in thefactory. Continuous innovation from the earliest times until was the engineer WilhelmWalther who developed the veryfirst AUTOMATIC SPRINKLER system inGermany, as long ago as revolutionary extinguishingconcept was based on the idea offighting the fire quickly, reliablyand comprehensively as soon as itdeveloped.

2 Today s modern sprink-ler SYSTEMS from TOTAL WALTHERGmbH are still based on this prin-ciple all through the range, fromspecial fast-response sprinklers tohighly sensitive life safety WALTHER SPRINKLER systemsare successfully used as an alter-native to passive fire protection,and they allow enormous freedomof design for commercial and indu-strial buildings. In addition, specialfast response sprinklers are used toprotect people and property inhotels and intricate support-ing structure of thehall at StuttgartAirport is protectedby SPRINKLER systemsfrom TOTAL schanl. engl. 14:36 Uhr Seite 43 SPRINKLER SYSTEMS FOR FIRST CLASS EXTINGUISHINGThe special extinguishing action ofa SPRINKLER system is based on theprinciple of selective SYSTEMS only operatewhere they are needed. Finely sprayed waterBecause the water which emergesfrom the sprinklers is separated in-to a fine spray, it vaporizes quick-ly, ensuring high cooling by ab-sorbing the heat from hot firegases.

3 This intensive vaporizationdisplaces some of the oxygenneeded to feed the fire, givingrise to an inerting protection successful extinguishingTOTAL WALTHER SPRINKLER systemsreliably confine fires to the initiallocation where they arise. Materi-als which have not yet been affec-ted by the fire are moistened inadvance so that they are less likelyto ignite. In addition, the watercools the structural elements of thebuilding, making them heat-resis-tant. Without SPRINKLER systemsfrom TOTAL WALTHER, the strikingarchitectural design of the hall atStuttgart Airport would have beenimpossible to implement. Modernhigh-bay storage units also call forspecial SPRINKLER protection. Theaddition of film forming foam con-centrates can extend the use ofsprinkler SYSTEMS to virtually everyrisk area in industry and large-scale natural choice for the environmentThe high water solubility of smokeand fire gases in the fine waterspray reduces harmful volume of extinguishing waterused in SPRINKLER SYSTEMS is optimiz-ed: a SPRINKLER will only go intoaction if it is heated to its actuationtemperature.

4 This ensures that un-necessary extinguishing water andresidues are avoided. There arealso environment benefits fromsprinkler protection: harmful emis-sions can largely be prevented byconfining a fire to the locationwhere it first arises, and by bond-ing toxic gases to the from the very start: the Walther system AUTOMATIC schanl. engl. 14:36 Uhr Seite 74 PLAYING SAFE ..Sprinklers are specially developedspray nozzles: they are sealed bya glass bulb, and they react auto-matically to the heat of a fire. Sprinklers go into action when theglass bulb bursts and the nozzleclosure is released. Water imme-diately emerges from the nozzle,and a spray plate effectively distri-butes it over the entire seat of thefire in the form of a fine shower ofwater droplets. Depending on theparticular risk, the area protectedby each SPRINKLER varies between9, 12 and 21m2. The choice ofspray plate depends on the typeand position of the SPRINKLER in-stallation.

5 The experts at TOTALWALTHER GmbH attach particularimportance to the optimal ratio ofdrop sizes for effective extinguish-ing and uniform moistening of theground. Thanks to its wide rangeof sprinklers, TOTAL WALTHER canoffer the correct SPRINKLER for sprinklerscan be mounted upright or pen-dent . For normal risks in industryand commerce, one SPRINKLER isused for every 12 m2. In warehou-ses, 9 m2are protected by onesprinkler. Low hazard spray sprink-lers can protect a maximum areaof sprinklersare fitted with a deflector whichcan be installed both upright and pendent . Since they sprayas much as 40% of the extinguish-ing water upwards, they are espe-cially suitable for installation undercombustible the actuation temperatureof the SPRINKLER is reached, thebulb bursts, the sealing elementis pushed out by the water pressure, and the water flowsonto the deflector and is distri-buted over the seat of the and pendent spraysprinklers and a schanl.

Thepipe network is filled with waterup to the sprinklers. If the glassbulb bursts, water will flow out im-mediately. In wet SYSTEMS , up sprinklers can be connectedto one alarm systemsare used in rooms exposed to therisk of frost. In the dry system , thepipe network is pressurized fromcompressed air upstream of thealarm valve. If a SPRINKLER opens inthe dry system , the pressure is re-leased. The alarm valve opens andwater flows to the open dry SYSTEMS , up to 250 sprink-lers can be connected to onealarm valve.
