The Type D3 Large Capacity Pro-tectospray Nozzles are open (non-au-tomatic) directional spray nozzles andthey are designed for use in waterspray fixed systems for fire protectionapplications. The 1 inch NPT Type D3Large Capacity Nozzles are externaldeflector type nozzles that discharge auniformly filled cone of medium veloc-ity water droplets.

inch NPT Type D3S Nozzles with indi-vidual strainers and K-factors of 1.1 to2.8 (15.8 to 40.3). Information on auto-matic Type EA-1 ProtectosprayNozzles is given in Technical DataSheet TD61 OA.

They are especially effective in cover-ing exposed vertical, horizontal,curved, and irregular shaped surfacesin a high density cooling spray to pre-vent excessive absorbtion of heat froman external fire and to prevent possiblestructural damage or spread of fire tothe protected equipment. In some ap-plications, depending on water designdensity requirements, they may alsobe used for fire control and extinguish-ment.

NOTES:1. Design data obtained from tests in still air.2. Design data applies to a residual (flowing) pressure range at thenozzle inlet of 20 to 60 psi (1.4 to 4.1 bar). For pressures up to 175psi (12.1 bar) consult the Technical Data Department.

Refer to the authority having jurisdiction for their minimum requiredresidual pressure.

3. The shapes of the Design Spray Profiles remain essentially un-changed over the maximum Axial Distances shown in the table.4. For axial distances of 2 feet (0.6 meters) and less and for nozzlespray angles of 65 to 140, the Design Spray Profile is the sameas the nominal spray angle.5. The maximum Axial Distances shown in the table are based onexposure protection.

ASTM B16 (CSSOOO), and the Pin isphosphor bronze.Orifice Sizes. Each orifice size has anumerical designation and the avail-able sizes are as shown in Table A.The nominal discharge curves and K-factors for the various orifice sizes aregiven in Figure C.Spray Angles. The nominal spray an-gles (included angles of discharge) areavailable as shown in Table B.Nozzle Placement. Where direct im-pingement of the water spray onto allof the protected surface is required bythe authority having jurisdiction, thenozzles are to be spaced and directedso that their spray patterns will com-pletely cover the plane-of-protectionwith the minimum required averagedensity; however, it is recommendedthat indoor nozzle spacings be 12 feet(3.7 metres) or less and that outdoornozzle spacings be 10 feet (3.0 me-tres) or less. Where rundown or slip-page is planned, e.g. exposure protec-tion of vessels per NFPA 15, thepreceding recommended indoor andoutdoor spacings also apply.When used for protecting the surfacesof a vessel, for example, the nozzlesare positioned normal to and approxi-mately 2 feet (0.6 metres) from thesurface. This approach, in conjunctionwith a properly selected spray angle,will tend to make more effective use ofthe spray as well as help minimize thedisturbance effects of wind/draft condi-tions on the water spray pattern.Spray Patterns. The Design SprayProfiles for the nozzle spray angles of65 to 180 are as shown in Figure Band apply to discharge pressures of 20to 60 psi (1.4 to 4.1 bar). Dischargepressures in excess of 60 psi (4.1 bar)will result in a decrease in coveragearea since the spray patterns tend todraw inwards at higher pressures.Refer inquiries on higher dischargepressures to the Technical Data De-partment.The maximum axial distances be-tween the nozzle tip and plane-of-pro-tection, for exposure protection, aregiven in the table that appears in Fig-ure B. When the axial distance fromthe nozzle tip to the plane-of-protec-tion is 2 feet (0.6 metres) or less, theDesign Spray Profile is the same asthe nominal spray angle for spray an-gles of 65 through 140.

The Type D3 Large Capacity Pro-tectospray Nozzles may be installedby using a Crescent type adjustablewrench.

Care must be exercised to avoid dam-age to the nozzles - both before andafter installation. Nozzles damaged bydropping, striking, wrench twist/slip-page, or the like, must be replaced.Water spray fixed systems for fire pro-tection service require regularlyscheduled care and maintenance bytrained personnel. It is recommendedthat the Protectospray Nozzles be pe-riodically inspected for loading/ob-structions, or other evidence of im-paired protection. The inspectionsshould be scheduled weekly or as fre-quently as may be necessary and, cor-rective action taken to ensure that thenozzles will perform as intended in theevent of a fire.
