VK520 - ESFR Upright Sprinkler (K14)
Viking Early Suppression Fast Response (ESFR) Upright Sprinkler VK520 is a fast response fusible element type sprinkler designed for early fire suppression. With a 20.2 nominal K-Factor and special deflector, this sprinkler produces large, high-momentum water droplets in a hemispheric pattern below the deflector. This permits penetration of the fire plume and direct wetting of the burning fuel surface while cooling the atmosphere early in the development of a high-challenge fire.
