Medium velecity water spray nozzle has an external deflector, which discharges water in a directional cone shaped pattern of small droplet size, The water is uniformly distributed over the surface to be protected! MY Nozzles are effectively designed to apply water to exposed vertical, horizontal, curved and irregular shaped surfaces to allaw coolng to prevent excess absorption of heat from extemal fire tnd avoid structurel damage or spread of fire. In some application nozzles may be installed to control or extinguish the fire depending on water design density ‘85 per applicable codes, The nozzle is used in deluge water spray system for special hazard fire protection appicstion ‘As the design and intent of specific water spray system may vary considerably, MY nozzle is made available in several combinations of onifice sizes (K-tactors) and spray angles. The minimum desirable pressure to achieve @ reasonable spray pattern is 1.4 Kg./Sq.cm. The water distribution pattern as shown in the graph in following pages is at en average aresaure af 2.0 Ko/Sec.cm. The change in pressure between 1.4 to 3.5 Kg./sq.cm, does not affect considerable change in spray angle ‘The spray pattern shown is with indoor application. System designer must. consider wind velocity while designing the system for outdoor apalication. Field obstruction if any affecting the spray pattern af the nozzle must alsa be considered. The nozzie may be oriented to any pasiticn as deemed necessary to caver the hazare, ocToBER, 2020 PAGE OF wD 108Tha Blow-off pligs can be used to prevent the depositing of foreign materials in the water way of the ‘nozzles, which could interfere with discharge of the spray nozzle, Slow-off plugs are optional and are FM Approved. Blow-off Plugs have identification mark with respect to K factor. For exemple, Blow off plug for nozzle having K-factar 22 will have Identification mark ‘of 22.

The application ff foam is on the basis that the risk comprises the ‘otal surface area of the fuel. The foam system design Guidelines generally used are in accordance with NFPA-11 standard, Foam Chambers are defined by NFPA-11_ as Type Il discharge outlets far delivering foam to the surface of a flammable liquid. Foam Chambers are widely used with the Balance Pressure Foam Proportioning System, Bladder Tank Proportioner or Foam Tender, SEPTEMBER, 2018) PAGE 1 0F 8 HD 254Bon SPECIFICATION Foam Chamber is an air aspirating foam discharge device, covering wide range of flaw fram 150 to 3300 litres per minute at 2.8 to 7 kg/so.cm. inlat pressure. Tha Foam Chamber contains a vapour seal ta prevent ‘he entry of vapour into the foam chamber and tho foam solution pipe. Each foam chamber is supplied with an orifice plate, designed for the recuired flaw and inlet pressure. ‘The ontice is field replaceable in ‘the event of change in design parameters. Foam is produced by introducing air into the foam solution stream. Tae inlet of foam chamber is designed ta create venturi jet which draws air into the foam solution stream, Air is drawn into the foam solution through the holes located on the foam chamber covered with stainless steel screen to exclude nesting birds and insects, The aerated foam 's directed into the deflector for the gentle apalication Gf the expanded foam, The deflectors are available in different mosels. Removal of cover plate from the top of the chamber allows the system ta be tested and a sample of the ‘expanded foam can be collected without remoung ‘the vapour seal or disconnecting the foams chamber fram the tank, Frangible glass bursting disc graphite [vapour seal) can be replaced easily The vapour seal is designed to rupture within 0.7 to 1.75 Kglsa.cm. (10 to 25 PSI pressure at inlet flange of Foam Chamber, as required by NFPA, UL & FM standard. The vapour seal will withstand maximum back pressure of 0.07 Kg/sq.cm. (1,0 PSD or equal to BEEmm of water column as specified by API for welded storage tank. If the requirement exceeds 0.07 Koi sq.cm, (1.0 PSD as in case of nitrogen blanketing system, then this equipment may not be suitable. The vapour seal is frangible glass. Vapour seal is supplied with holder and for spares it can be with or wwithout holder. The ‘O' ring used for seal are Nitrile rubber and optional Viton is recomended for polar solvent. SYSTEM DESIGN REQUIREMENT The NFPA-11, @ standard for low expansion foam, provides the essential requirements of an appropriate designed foam pouring system, these are identified {and outlined as below: The Foam Deflector is used with the Foam Chamber The aarated foam fram the Foam Chamber is directed In to the deflector for the gentle euolication of the expanded foam. The dafiectar reduces che expanded foam velocity and allows the foam to slide down the rank wall 40 Fine PRoTECT ‘pvr. 11D. (a) Number of Foom Chamber: The number of foam chambers required is, determined by tank iameten Where two ‘or mare foam chambers are required, they shall bbe spaced equally around the tank periphery and each Foam Chamber shall be sized ta deliver foam at an approximately same rate. Please refer graph to select unit that wil provide required minimum foam —solutian application rate at the available operating pressure of the Foam Chamber For minimum number af Foam Chamber requirement, kindly follow the recommendations as per NFPIAVOISD er as per the governmental codes or ordinances wherever applicable. (b) Minimum Foam Solution Application Rate: The minimum foam solution application rate is the rate at which the water and foam concentrate in correctly proportioned ratio should be delivered to the surface of a storage tank under protection to control and extinguish the fire For minimum application rate requirement. follow the recommendetians es per NFPAVOISO. or governmental codes or ordinances wherever applicable TESTING & MAINTENANCE Carefully unpack Foam Chamber While unpacking ‘and installation it is to be handled with care and shacks to be avoided. Check visually for any demag- ‘8s. While installing ensure that Foam Gramber is not under strese due to any misalignments in installation or variations of system piping. Enaure that the strainer assembly is clear from any blockages or demages. If strainer assembly is either blocked or damaged, it will adversely affect the perfarmance of the equipment, Qualified ard trained person must commission the system.
