Description

Viking’s Early Suppression Fast Response (ESFR) Dry Pendent Sprinkler VK512 is a fast response fusible element type sprinkler designed for use in storage areas subject to freezing and supplied from a wet system only, in an adjacent heated area. With a 25.2 (363 metric) 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.
