VK533 - QR ELO Fusible Element Upright Sprinkler (Storage-Density/Area) (K11.2)

The Viking Quick Response ELO Upright Sprinkler VK533 is a thermosensitive fusible element type spray sprinkler available in several different finishes and temperature ratings to meet design requirements.  The extra-large orifice provides greater flows at lower pressures than standard orifice or large orifice sprinklers. This feature allows reduced pipe sizing for hydraulically calculated sprinkler systems, which require high densities of water.
