Abstract: An injector (22) for use with a misting system (20) includes a main body (30) and a converging-diverging nozzle (58) positioned within a channel (54) of the main body (30). A composition (50) is placed in a mixing chamber (38) integrally formed with the main body (30). A portion (86) of water (56) flowing through channel (54) of the main body (30) is diverted through a conduit (74) and into an upper end (82) of the mixing chamber (38). The water (56) turbulently mixes with the composition (50) to form a mixture (88) of the composition (50) and water (56). This mixture (88) is siphoned from a lower end (70) of the mixing chamber (38) through a fluid port (62) and into nozzle (58), where it is subsequently discharged from the injector (22).

Abstract: A fog generating system (20) includes a fluid feed conduit (22) and extension tube assemblies (26) spaced along the conduit (22). The assemblies (26) include nozzle fittings (40) coupled to extension tubes (32). Misting nozzles (44) are releasably engaged with the nozzle fittings (40), and are recessed within the nozzle fittings (40). Installation entails arranging the system (20) on an interior side of an installation form (90), and securing the nozzle fittings (40) using fitting plugs (50) so that an open ends (60) of the nozzle fittings (40) abut the form (90). The fitting plugs (50) further form a fluid resistant seal for maintaining the assemblies (26) under fluid pressure during installation. The system (20) is embedded in a concrete material (124) for the structure (120). Following removal of the installation form (90) and the fitting plugs (50), the misting nozzles (44) are installed within the nozzle fittings (40).

Abstract: A misting pump system (20) includes a housing (22), an electronic section (62), and a water transfer section (80). The housing (22) includes a base (48), a front panel (24), a rear panel (26), a cover (50), and a barrier wall (52). The barrier wall (52) is coupled to a floor (66) of the base (48). The barrier wall (52) extends from the floor (66) to a roof (68) of the cover (50) to form a first compartment (76) and a second compartment (78). The water transfer section (80) is located in the first compartment (76) and the electronic section (62) is located in the second compartment. Openings (108, 118, 132, 140) in the barrier wall (52) provide an access between an inlet (89) and an outlet (91) of a pump (88) of the electronic section (62) to the water transfer section (80). The barrier wall (52) is configured to substantially prevent water issuing from a water leak in the water transfer section (80) from passing into the electronic section (62).
