VK504 - ESFR Dry Pendent Sprinkler (K16.8)

Viking's Early Suppression Fast Response (ESFR) Dry Pendent Sprinkler VK504 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 16.8 (242 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.  Sprinkler VK504 may be used in the protection of most common storage materials, including encapsulated or unencapsulated Class I, II, III, and IV commodities, and Group A Plastics. The VK504 successfully meets new UL 1767 test standard and compliance program for ESFR sprinklers installed in rack storage with high clearances to ceiling (20 ft or greater).
