Viking Corporation, a global provider in fire protection and life safety systems, announced that its K28 ESFR sprinkler is now FM Approved to protect high-piled storage up to 50 feet (15,2 m) in storage facilities with ceilings as high as 55 feet (16,7 m), without requiring an in-rack sprinkler system. As a result, the Model VK514 pendent sprinkler can significantly reduce installation and maintenance costs while increasing racking flexibility in warehouses as high as 55 feet (16,7 m).
The new FM Approval is offered in addition to the sprinkler’s existing UL Listing, which provides ceiling-only sprinkler protection in warehouses up to 48 feet (14,6 m) in height. The FM Approval classifies the Model VK514 as a Quick Response Storage sprinkler, approved to protect Class 1-4 commodities and Group A, cartoned unexpanded plastics.
Storage sprinklers
The FM design specifies a design pressure of 80 psi (5,5 bar) with a remote area consisting of nine sprinklers, installed with three sprinklers on three adjacent branch lines. The K28 ESFR sprinkler is available in both ordinary and intermediate temperature ratings – 165°F (74°C) and 205°F (96°C) – and with a 1” NPT or 25mm BSP thread size.
Viking offers the industry’s most complete line of storage sprinklers specifically designed to suppress high-challenge fires, without requiring in-rack sprinkler systems. In addition to the K28 ESFR pendent sprinkler, Viking also offers K14, K17, K22 and K25 ESFR sprinklers. Viking’s line of storage sprinklers also includes dry-type ESFR pendent sprinklers (K14 and K17) as well as CMDA, CMSA, ELO, and EC storage sprinkler options.
