Viking's K28 ESFR Sprinkler Approved to Protect Up to 50 foot Storage Facilities with Less Water
The Viking Corporation, a provider of fire protection and life safety systems, announced an enhanced FM Approval for its K28 ESFR sprinkler. This new FM Approval allows the Model VK514 sprinkler to protect 50 ft (15,2 m) high warehouses with significantly less water than other available protection methods.
A design of nine sprinklers in a 3x3 array at 40 psi (2,8 bar) is now possible, provided that a secondary calculation is satisfied for four sprinklers at 80 psi (5,5 bar) in a 2x2 array. In most applications, these new calculations will enable smaller pipe sizes and reduced pump sizing.
The new FM Approval is offered in addition to the sprinkler’s existing FM Approval for racked storage up to 50 ft (15,2 m) in facilities with 55 ft (16,7 m) high ceilings. The sprinkler is also UL Listed for ceiling-only sprinkler protection in warehouses up to 48 ft (13,1 m) in height.
The new FM Approval classifies the Model VK514 as a Quick Response Storage sprinkler, approved to protect Class 1-4 commodities and cartoned unexpanded plastics in racks with 6 ft (1,8 m) aisle widths.
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.
